Leith Hill Varsity Match, 25 Feb

(Cross posted from Attackpoint. See also my leg by leg analysis and mistake and speed analysis.)

Leith HillOxford vs Cambridge Varsity Match at Leith Hill, Surrey. Running for JOK (ex-Oxford) on the Men’s A course.

A great race for me personally, in beautiful, technical terrain. I had some personal demons to conquer on this map, having had a disastrous run in my only previous outing here. Leith Hill is a small, technical area, quite Scandinavian in nature, particularly with the sunny, cold weather, open and intricate detail and a dusting of snow on the ground. Due to the size of the area, the race was in two parts, with a map change near the start, around half way around. The planning style was very much taking us into the difficult area for a couple of controls, then out for a couple of long, easy ones, and then back in, over and over again, until you made a mistake. I forced myself to run at a slower pace than normal, and pleasingly did not make any mistakes that cost me more than a minute – it’s been a while since I’ve had a clean race.

The first three controls were a warm-up through the edge of the tricky area, then a couple of easy ones. I actually ended up at 5 before 4, as I dropped a little low around thick vegetation, but this was OK as it was only a few metres from 4, and my split from 4 to 5 has got to be the fastest of all – 18 seconds! The course then did a long loop in easier terrain – I was a bit slow here, although some of the features were very subtle. After another technical section, which I unwisely took a chance on and got lucky on, it was time for the map changeover.

Leg 17 was long and tricky, and relied on an accurate compass bearing, but I was lucky to strike it pretty much on. After another jaunt through the difficult bit, which I had no issue with, there was another long leg away, I was extremely lucky here as I hit the control while thinking I was quite some distance from it. One final run through the tricky section was again OK, I was going very slow here so as not to mess up a so-far good run. The penultimate leg was long, and I switched off a bit – dangerous, as I deviated by about 30 degrees, and had a long plod to get back on the line. Probably only a minute’s mistake as I picked up the pace.

Unfortunately, Oxford and Cambridge were unable to run on the Saturday, as the latter team were stuck on a motorway. So they ran on the Sunday, in cloudier but still pleasant conditions. I was a little bit hungover so just spectated at the race, before psyching myself up for the long bike home. In the end, Cambridge took the team trophies, just, as they had strength in depth, and Alan Elder took the Men’s Individual Trophy for a storming race in 62 minutes – you have to be pretty good to run at that speed and not make big mistakes, in an area like Leith Hill. Helen won the Women’s Individual though, so Oxford didn’t quite go away empty handed.

Burnham Beeches and Egypt Woods Regional Event, 19th Feb

(Cross posted from Attackpoint. See also my leg by leg analysis and mistake and speed analysis.)

Burnham Beeches extractBurnham Beeches is one of my favourite areas – but it was a shame the weather wasn’t great, a gloomy overcast day, with rain for the second half. The map had a new section at the top, which most courses started in – I didn’t think too much of it, as it wasn’t technical. The real “meat” of the course was later on, down in Burnham Beeches itself.

Leg 12 to 13 must be the longest leg I’ve ever done – almost 2km, I think. I managed to accidently visit Control 23 on the way to 13… But I had a clean run up until No. 16, at which I misread the map rather badly. 17 was also bad, as it was very technical, and I just ran in to the area, hoping to hit it – never a good idea in retrospect. About 6 or 7 other people were milling around trying to find it too, so once one person did, there was a pack punching and moving off. I wasted time at 18 trying to lose the pack, and then 18-19 was another super-long leg – again well over 1km.

Another silly mistake near 21, a parallel error – but at least the 3 people following me therefore made the same mistake. From there on it was pretty straightforward, although there were still a few long legs left.

The course overall certainly felt like 12+km! Despite my good time (<8mins/km) I still finished well down the pack. That’s the annoying thing with M21L – being the hardest course, all the really good people run on it. If I had done M21S at the same speed I would have been well up the leaderboard. Still, as the phrase goes, better to be near the bottom of the top class, than near the top of the bottom class!

Oxford were out in force, including Kat and distracted, the latter who (again) beat me by about 5-10%. One day I’ll beat him, one day…! 😉

South Ashdown MV Regional Event, 12 Feb

(Cross posted from Attackpoint. See also my leg by leg analysis and mistake and speed analysis.)

Ashdown Forest is the home of Winnie the PoohI was expecting a forested course today, as it’s in Ashdown Forest, but the course was almost entirely on grassy and heathery moorland, with various tank tracks providing fast routes. The area was cold, raining and misty when I arrived, so I had planned to run just the 8km short course – especially as Nick Barrable, Simon Evans and the Rollins were all running M21L. However, the maps had run out (I hadn’t pre-entered) so I ended up running the long. 11km in the rain was always going to be tough, but I got off to a good start, making only minor mistakes (<1 minute each) up to control 7. I was going well, running hard, and could be posting a good time in the tough conditions. Then, things went a bit downhill.

Once again the “rough open with scattered trees” colouring was indistinguishable from white forest. But my main annoyance with the map is that it didn’t mark on most of the gorse clumps in the rough open – and neither did the control descriptions. This meant I wasted a lot of time (5-10 minutes each) at both 8 and 12, these were hard, technical controls, and trying to navigate off the gorse clumps caused big problems for me. The continual rain started to increase slightly, and the mist closed in, making the moorland legs very technical and very physical.

South Ashdown extractControl 8, as mentioned above, was a disaster, needing two relocations to fix, thanks to much confusion over marked and unmarked gorse bushes. 12 was a very technical control and I ended up a long way from where I should be. In the end, it was hidden in a gorse bush (unmarked), that I had run past at least twice before in my search. Some parts of the map felt very remote in the murky rain – even though it’s only Sussex, it felt more like the Scottish Highlands. 15-16 was possibly the hardest leg I’ve ever done – it was only short, with little climbing, but the marshes I tried to cross in the rain were man-eating – I ended up suddenly up to my waist several times, I’ve never been so glad to see a control. I fell in several more man-eating marshes, and was flat on my face several times after then too – it was a real fight to get around! I did however still have plenty of energy and was able to run well where I could. After a final section through pleasant woodland, the penultimate leg was a tough uphill stretch and the only leg for which I walked part-way.

As before on long, cold and wet courses, I suffered some pain in my lungs, after around 8km, which is persisting a little bit now. As I was also completely soaked, I was pretty miserable at the finish, but was relieved and glad I got around OK, on a long course, with enough energy to keep going. As is almost always the case, if I hadn’t made my big mistakes, I would have had a respectable time.

I really hope it doesn’t rain at Burnham Beeches next weeked though. With this and Eridge, I think I’ve had enough rainy courses for this year…

Mistake analysis:
1: Poor navigation
3: Poor pacing
6: Bad attack point
7: Poor route choice
8: Poor route choice
12: Poor navigation
16: Poor route choice
19: Poor navigation
27: Tiredness

Godshill, Turf Hill & Millersford WIM Regional Event, 5th Feb

(Cross posted from Attackpoint. See also my leg by leg analysis and mistake and speed analysis.)

Godshill extractThis was a part of the New Forest I haven’t run in before. Got a lift from Southampton (where I was out the night before) – many thanks to distracted and OUOC. Arrived very hungover and sleep-deprived and having only eaten two bowls of cereal in the last 24 hours, so I decided to do the short course.

I always like running in the New Forest, it is big, open and scenic, with ponies and the odd wild boar roaming free – and it’s all mapped. Today’s map was not technical, but it was beautiful to run in, with beautiful vistas, fast moor and varied woodland. Plus it was crisp and sunny, and not too cold for February.

I took it fairly easy for most of the race, careful not to aggravate the pain, and allowed an injury-hit distracted to still beat me by 4 minutes. What a world of difference from last weekend though – today I made no serious mistakes and only one that cost me more than a minute (and it was only because I was being lazy.)

The uphill finish was a sting in the tail but didn’t detract too much from an enjoyable, if technically easy, race.

A comment on map colouring for planners and mapping experts: For “semi-open”, please do white dots on orange, not the other way around! It was the other way around on today’s map and it meant the semi-open was virtually indistinguishable from white forest, while of course being different on the ground – and definitely threw me off my navigation in a couple of places.

Mistake analysis:
Leg 10: Hesitation
Leg 19: Poor navigation
Leg 20: Poor map-reading

Cold Ash BKO National Event, 29th Jan

(Cross posted from Attackpoint. See also my leg by leg analysis, mistake and speed analysis, and the other M21L splits from APers. Wow, does AP do stats or what!)

Oh, blimey. What went right on this race? Not a lot. I better start with the positives – lovely crisp weather, technical and enjoyable area, and my recent training means I can definitely run faster and for longer, without completely running out of energy. And the distance (almost 13km) was not a problem – I only felt really tired in a couple of places.

Now the bad. I made mistake after mistake after mistake. Probably the most number of mistakes I have ever made on an orienteering event. It wasn’t that it was very technical – it was a tricky area and the map was not perfect – quite a few non-existent clearings around – it was just that I made bad route choices, lost concentration, and made huge navigational errors all the way along. I know bad workmen blame their tools, but I’m pretty sure my compass was stuffed. Maybe it was that large “Emit” brick I had to carry around. And the scale was 1:15000, smaller than normal, but due to my relatively increased fitness, I overcompensated and overshot a lot. I think the main cause was I was running quite fast, thanks to my recent training – too fast, in fact, for me to navigate accurately and properly. Which kind of leaves me in a quandary as regards further physical training. I think I need to take up Armchair Orienteering in a big way and keep the mind sharp.

Cold Ash map extractThe first control was bad. I somehow missed an obvious path, and was 30 degrees wrong, and overshot. No. 2, I again headed 30 degrees wrong, meeting control 24. But I at least spiked it. Towards number 6, I felt a little tired, and a branch spiked my eye – could have been really nasty, but my contact lens dropped out and I spent a couple of minutes fixing that. Towards number 8, my feet started cramping again (as two weeks ago) so I stopped straight away this time and relaced loosely. 10 was a bingo control and I failed to notice a good route choice. 11 was a massive error of judgement – to lose a runner, I decided to go down a road (failing to spot a much better road route), mistaked a ride for a path, got stuck in a marsh, ran back down a hill and back up again. Aaargh!

No. 14 was a complete disaster, it should have been trival, but it was a very technical control and I some how ended up on the wrong path and had to do a relocation. 20 was a poor route choice. I was feeling (technically) lazy and took a long but easy route around, adding 600m to the leg by failing to spot a direct and obvious path, and then missing the (technical) control. And 22 was a complete nightmare and my worst leg of all (8 minutes for 400m!) I again drifted 30 degrees off, ending up way beyond the control, cold and very confused. I had a complete brain block, was unable to navigate and relocate, and just freaked out. Eventually I got some self control back and managed a relocation. I really hope I never have a control like that again. Looking at the leg, it was not particularly technical at all – lots of line features.

Special mention of control 19, it wins Location of the Year for being in an utterly surreal place – in white (runnable forest) but the forest was completely pitch black, with nothing on the ground except needles – like a table. And the control was in the middle, glowing eerily in the darkness. It was like something out of Lord of the Rings, and was truly magical.

Overall a truly fine area. Just a shame I had such a bad race on it.

Mistake analysis:
1 – Poor pacing/scale awareness
2 – Navigational error
6 – Fatigue
8 – Hesitation
10 – Bingo control
11 – Poor route choice
14 – Poor attack point
17 – Poor route choice
20 – Poor route choice
22 – Navigational error
25 – Hesitation
26 – Navigational error

I’ve only mentioned the biggest mistake on each leg, on some of these legs I made just about every possible kind of mistake! Incidentally I may start using just the AP’s own mistake analysis for future races.

Tilgate Forest SO District Event, 15 Jan

Tilgate Forest map extractCross posted from Attackpoint

Overcast, but not too cold today. This should have been an area I did well on – reasonably technical and flat – but I made too many mistakes, and also cramped up. The area was full of paths and differing vegetation – in fact it was quite difficult to read the map in places. Or maybe my eyesight’s just getting worse…

I got off to a good start running hard as I had another runner right behind me. Unfortunately I was running too fast to read the map properly, and so towards No. 6 I thought I was on a parallel track, so wasted a few seconds looking for a non-existent feature… 6-7 was a long leg – over 1km. My feet started to cramp up badly here which was very painful. This is not something that has happened before, and may be a combination of running hard in my cheap backup shoes (my regular ones were still covered in mud from Eridge) and tieing up the shoes too tight. From 7 to 8, I stopped for a clear 3 minutes to redo the laces and try and get rid of the cramp – it worked, but I had lost a lot of time by that point.

Control 11 was tricky, planted very low in a small ditch – a bit of a bingo control. For 12, I made a map-reading mistake and somehow ended up on the wrong side of a lake, and for 13, I got stuck in a thicket. Then followed a number of mistakes due to tiredness and poor route choice. None of these mistakes cost me more than a minute each, but they all add up… The worst one was at 19, where I first came out east when I meant to go north; then didn’t aim off, turning away in the wrong direction from my “attack point.” Finally, the 460m, slightly uphill run-in was a bit of a killer.

All in all, really not good a race at all. I much preferred the mud-bath at Eridge last week, although few would agree. Next event, I’ll use my proper O-shoes, tie them loosely and try and get a proper meal before the race!

Simon Evans had a storming run and came in in 59:38. He beat me on every leg bar one. One to watch this season.

Mistake analysis:
6 – Parallel error
7 – Hesitation (foot cramp)
8 – Hesitation (foot cramp)
12 – Poor map reading
13 – Unanticipated hazard
14 – Fatigue
17 – Poor route choice
19 – Poor navigation, poor attack point

New Map Books

I received a couple of excellent cartography-themed books this Christmas:

Mapping Hacks (referral) is an O’Reilly book and is right up my street – I had it high on my wish list. Although unfortunately it was published just before the Google Maps API was made available and everyone when Google Maps Mashup crazy, it nevertheless contains a great pile of neat, computer-based GIS and mapping tricks, and background information – such as how to convert between the various coordinate systems, plot the “great circle” on a flat map, and even how to publish your own geodata to the internet for others to use. Note though that some of the tips are PC only, and some are only useful in the US, due to the vast amount of geographic information available for free on the internet from the US Military and US government. Sadly, the UK is a bit behind in opening up its GIS data, so another US military website, GNS is where I’ve sourced a list of coordinates for UK features for playing with one of the hacks. The book has a website (or rather, the latter spawned the former.)

You Are Here (referral) was an unexpected, but similarly essential present. The book is described as “Personal geographies and other maps of the imagination” – think of it as a glossy art book – but entirely composed oa maps, old and new. The presentation is top-quality and the “artwork” is simply beautiful. Daniel Wallingford’s A New Yorker’s View of the United States (c. 1939) reminds me a lot of a more contempory map I saw once of “The UK, according to Londoners” which has Great London occupying most of southern England, and “icebergs and floes” somewhere up in Scotland – the roads stop at Jocks Lodge somewhere in Northern England, and beyond, Here Be Dragons. Similarly in Wallingford’s piece, Staten Island is just north of Florida, and the state of Hollywood (capital, LA) is just south of California – which is itself dwarfed by the state of San Francisco.

Eridge Old Park SAX Regional Event, 8 Jan

Eridge map extractEridge Park is a rather nice, grand old county estate in East Sussex, comprising a large central deer park (fast, featureless, open) surrounded by several areas of complex, quite steep woodland. Or, at least, it would have been rather nice if it hadn’t rained continously throughout the course. I ran M21S, mainly because the 11.7km M21L sounded like a little much after Christmas excess. But, despite the rain and the mud (and wow, there was so much mud!) I got around the course pretty well – 5 mistakes in the first 7 controls, then none for the remaining 14, and got a pleasantly good time. I really didn’t push myself though, and got the end with enough energy for at least another couple of km. A pleasureable post-race afternoon was spent out of the wind and rain in a local pub by Eridge station, where the usual post-race analysis, splits games and real ale drinking was carried out with fellow JOKers and SLOWies. I’ve now got to spend the next three weeks doing some serious training for a national event at the end of the month at Cold Ash, for which I’ve foolishly entered Long without knowing the course distance.

Mistake analysis:
2 – (Very) poor route choice
3 – Navigation error followed by parallel error
4 – Unanticipated hazard (tricky felling)
6 – Unanticipated hazard (steep slopes + green + mud)
7 – Navigation error, poor pacing, possibly poor mapping.

The extract shows controls 2, 3 and 4, all of which I messed up. I took a very poor route choice to No. 2, which involved a roundabout route across various streams followed by a big climb – if I had studied the map, there was a much more obvious route which involved a short climb followed by an easy jog along a path. No. 3 was really daft of me – I came out of the control heading due east, and in the easy terrain, kept going straight instead of swinging around. I then made a parallel error by mistaking a fork in the stream, and headed up it – almost to No. 4. And 3 to 4 was made difficult by felling extending lower than marked, plus it was extremely slippy in the mud and the rain. My compass and map were both caked in mud by this point.

John Muir Country Park ELO “Festive Frolic” Local Score Event, 27 December

John Muir Country Park ExtractThe annual “Festive Frolic” put on by my old club, ELO was this morning. This year, for the first time, it was at the John Muir Country Park (rather than Yellowcraig) and was on a newly updated map – half the map is on a flat plantation, and the other half is on the changing dunes of “Spike Island”. This year’s race was “Sud-O-Ku” – going to each control on the score reveals a symbol (with coordinate) to be added to a grid – once all the controls are done, the Sudoku puzzle can be solved and the first back with a completed puzzle is the winner. However, 50 other features on the map were flagged with tinsel and another symbol and coordinate, so if you couldn’t do the puzzle, you could run around hoping to see as many of these as possible. In the end, I spent too long trying to find the extra tinsel features, and by the time I sat down to solve the puzzle, it was too easy – and others were already back. One of them was Jamie Stevenson, the British Champion and UK squad member – he didn’t win. Once again, nice weather – cold, with a bit of snow in the air, but no rain or gloom. The complementary soup at the end was timely, though.

Joydens & Chalk Woods DFOK District Event, 18 December

Joydens Wood extractAfter last week’s walk to the start and then painful limp home, my sprain seemed to have fixed itself more quickly. So, it was yet another cold crisp morning that found me in yet another South East London forest.

I ran down a course – Blue, so as not to push my luck with the sprain – however I didn’t feel a thing until I stepped awkwardly on a log on the way to No. 2. I went very gingerly to 3 and 4, deciding to retire, before changing my mind as the pain quickly went away this time – and went on to finish 3rd out of 25 on the course – however, this is more symptomatic of the quality of competition on a Blue standard course instead of my normal Brown – I wasted at least 5-6 minutes between 2 and 4 due to worrying about the injury, and my pace was 10+mpk – I would normally do 8-9 on an area like that.

Joydens Wood is not a great area – it has a lovely central section with fast, pleasant running (it was yet another cold, crisp and sunny day) but most of the rest of the forest is covered in thick vegetation, even in December. Also there were a couple of map inconsistencies and a real bingo control at one point. Still, it was nice to get out of the house and around another new map.

Joydens Wood has a famous dyke running through it that was built 1400 years ago to keep the (Roman) Londoners out of Saxon Kent! The planner had some fun and routed the final couple of controls directly up the dyke – nice!

Mistake analysis:
1: Poor mapping [misleading detail around control]
2: Hesitation [injury!]
3: Hesitation/Poor route choice [quickly learnt to avoid all marked undergrowth on this map]
4: Hesitation [almost retired here]
10: Bingo control [in a pit in featureless, dense undergrowth]
11: Map-reading error
12: Poor mapping [control was 70m SE of indicated location, in gully]
14: Poor route choice/Navigational error

Most of these mistakes were pretty minor, still 8 on a 15 control course in an easy area – I’m clearly slacking at the moment! Mind you, 3 were through no fault of my own, so not the greatest map either.
