E9: Gridded

So, I ran in the Nike Grid ARG (alternative reality game) on Saturday, concentrating mainly on the E9 postcode in Hackney, but also going jogging around the City of London (EC1, EC2, EC3 postcodes) doing an informal City of London Race. The aim of the game was to log runs between four specially designated phoneboxes in each postcode, dialing in at the start and end of each leg. The more legs done, the more points you got – bonus points were available for running early/late, doing a fast run, completing every possible leg, and the most number of legs.

My strategy was hampered by having a severe hangover from the night before, so I didn’t make it out of the house until 3pm (the game ran from 8pm-8pm) and was pretty dehydrated. It was also a very warm day – and, to make things worse, the phoneboxes themselves acted as heat reservoirs. One City leg went via a supermarket and its chiller cabinet…

In my first session I essentially ran all of the six possible legs between the four phoneboxes, and several extra legs between the two closest ones. In the later session (after my jog around the City) I again aimed to run all six possible legs, getting the fastest split bonus for each, but realised near the end I wasn’t going to make it to/from the far one, so repeated some of the smaller legs. The many people enjoying a cool drink in the garden outside the Royal Inn on the Park, immediately opposite the most southerly phonebox, must have wondered what was going on.

The map below shows the routes I took between the four phoneboxes, marked with green rectangles:

In total I ran around 16.5km (10 miles) in the E9 postcode. The phonebox dialing process meant I essentially had a two minute rest after every leg – the longest of which I did in just under 10 minutes. My shortest leg was 1m 26 – I tried this one again and again but my times kept getting worse with each attempt!

I ran into the last box about 10 seconds before the game closed – I had to push it for this final leg and got bonus points for running this leg in the fastest time. (In fact I think I picked up all six of the fastest leg bonuses during the day.) The Nike team were filming this last phonebox and interviewed me afterwards.

I was extremely unlucky not to win – notice how close I finished to the eventual winner in the leaderboard below. However I did get 110 of my points in the dying seconds of the race. The guy who finished third appeared at the same phonebox a minute later (i.e. too late) and, had our arrivals been reversed, he would have finished in front of me.

Although I didn’t win, a friend won not once but twice in a different postcode, so I’ll at least get to see what prizes I missed out on!

There were some “bugs” in the game – certain phoneboxes in the City had quite unresponsive keypads which made it difficult to clock in at the end of the leg. Quite often, the automated service appeared overloaded and stopped talking half-way through, leaving you wondering whether the run had been correctly logged or not. The game leaderboard was updated in real time, which was impressive, but it was written in Flash so I was unable to see how I was doing on my iPhone. (A dedicated iPhone app would have been cool.) There luckily weren’t many players in my postcode, but many more would have clogged up the system – it took 1-2 minutes in the phonebox to stop and start each leg. Some clarity on how many points were on offer would have helped me refine the strategy, although I suppose part of the challenge is figuring it out for yourself. A couple of “test” 3am short legs I tried on my way back from the pub didn’t count for “early” bonus points, although game messages suggested they would at that time. Finally the maps weren’t too great – some phoneboxes were in the wrong place. I had however done a bit of online research first though and used a marked orienteering map instead, so this didn’t affect me. A friend of mine greatly benefited from one phonebox not being themed – he was the only person in that postcode who realised it was still a game phonebox and so completely destroyed the opposition.

It must have been a nightmare to organise, with nearly 150 postboxes scattered across many miles that needed theming, maps distributed to them, checking and fixing them – not to mention answering the many and varied questions and complaints on the Facebook event page, and writing the software to handle the automatic logging, updating and cheat detection.

Overall I really enjoyed the style of the event. There was definitely something of “The Matrix” about sprinting through the grimy streets to a phonebox (themed in green and black, too!) and breathlessly grabbing the receiver in front of surprised bystanders. All things considering, it was a nice “Real Life 2.0” take on the street orienteering theme. Not sure we’ll see this repeated – Nike generally organise a “concept” event in London yearly but each year’s idea changes dramatically to keep things fresh – however I would certainly love to try it again.

Carcassonne

Final Control at Night (6533)

I wouldn’t normally fly several hundred miles just to go to an orienteering event – but then, an orienteering event in the Cité de Carcassonne in southern France was never going to to be just another orienteering event.

Actually there were three events in the one weekend, a middle race on the Saturday afternoon, the Carcassonne sprint in the evening, and a long race on the Sunday morning, which made it an even better reason to travel down.

Perhaps the biggest surprise of the weekend was that I enjoyed the other two events as much as the “headline” sprint in Carcassonne – indeed, I thought the middle race, held near Montlaur, around 20km away, was on some of the most amazing terrain I have ever run on in fourteen years of competing. It is difficult to describe – imagine tinder-dry bare earth ridges and gullies – stable enough to run on, but often too steep to run off the edge of. The steepest edges, typically those steeper than 45 degrees, were marked with “impassable cliff” lines on the map. There were two pockets of this intense terrain separated by a run through some of the very many vineyards in the area. The bottoms of the gullies tended to be guarded by very prickly bushes, so staying high was the less painful, if more technical, option. I was pleased with my time of just over an hour for the 3.8km course – getting up any speed was difficult in the intensely technical and physical terrain. Orienteering doesn’t really get any technical – or enjoyable – than this. Multiple world-champion and local boy Thierry was also running my course – and finished in exactly half my time – amazing!

I was impressed with the facilities that COORS (the organising club) had laid on for a relatively small-scale event – with commentary, traders and a bar. If only the French had heard of portaloos, it would be a perfectly organised event!

Then in the evening, it was time for the sprint race through the medieval cobbled streets of old Carcassonne. The walled city is quite small but is on a steep hill and has two complete sets of walls, with various doorways, passages and other intricate map detail. Our start times were at nearly 11pm, the reason for the timing of the event became clear the following day – the streets are crammed with tourists during the day. However, the late Saturday night start meant we had to decide if and when to eat and drink. Running on a full stomach and after a few glasses of wine might not be the best idea, but you can’t really go to France and not enjoy the local specialities…

The race itself was short and intense, with 17 controls and 190m of climb in the 2.7km course. The route led in and out of the city several times, including a steep climb up a grassbank, and running through the (dry!) moat to the finish line. The walls are floodlit at night, but there were plenty of dark passages and alleyways where headtorches were needed. I finished 9 minutes down on Thierry, perhaps the only time I’ll be so close to the world’s top orienteer, although to be fair he did get around in 20 minutes.

carcassonneshort

Unfortunately Jayne twisted her ankle, falling in one of the dark pits on the course, so it looked like getting back to our B&B (in the countryside overlooking the city) could be a challenge, until we managed to persuade an organiser to give us a lift back. By now, the big meal, wine, two races, and 4am start were starting to catch up with me…

Carcassonne Ramp (6481)

Finally, on Sunday, was the long race, back in Montlaur. The distance was less than 10km (with 400m of climb), but I was bracing myself for an epic, and so it proved to be. I made it back in 110 minutes, having spent 15 minutes on the wrong hillside about half-way around the course – one of those awful mistakes compounded by various features apparently fitting to the map. Although the landscape was largely open, it was full of vineyards, a blaze of yellows and reds, but tricky (and painful) to get around. There were some pockets of extreme complexity on the map, and also some epic legs – No. 2 to 3 was 2.2km across the valley and up a hill. Still, a rewarding challenge. Thierry again impressed by running at roughly double my speed.

After the race was the prize ceremony – there were a few other Brits there and impressively, quite of them got prizes – it says a lot about the area that the winners got a bottle of wine and a bottle of pressed apple juice, and the runners up got the bottle of wine.

Then it was time to head back to the airport and back home – but not before a combination of Google Maps missing a major bypass, and the reluctance of the French to sign destinations via their motorway network, on their signs, meant we took an unexpected detour through various villages on our way to Toulouse.

A top quality orienteering weekend.

Dunwich Dynamo 2009

img_0389
This is an annual 180km self-supported ride from London Fields in Hackney, to the beach at Dunwich in Suffolk. As it’s a free turn-up-and-go event, it’s all quite informal – people just turn up at the Pub in the Park and then start to head off. The catch – it’s a night time event. I started at 8:50pm…

I was riding with Jenn and Michal, also trying out various new accessories I’d bought in the day – a fell-runners’ bag, saddle bag, frame bag, padded shorts, a proper cycling top, cleats and a couple of bike lights (which proved to be woefully underpowered.)

There most have been close to a thousand cyclists in this year’s Dynamo, taking advantage of the calm, dry and clear weather, although it got surprisingly chilly quite quickly.

The pace was far faster than I was expecting – once we had passed the highest point of the route (Epping Forest) the pace really went up and we pushed hard until the food stop at 100km, arriving at around 1:15am. The pace then on was also quite fast, at one point a wonderful 10km with the Dulwich cycling club peloton. Then, as dawn broke properly, we started to tire a lot.

img_0395

We finally made it to Dunwich at 6:10am (ride time 7h 23, + 2 hours of breaks) where the cooked breakfast in the cafe was very welcome – the rain shower, the first of the night, wasn’t. We took a risk, cycling 8km through the second rain shower to get the first local train of the day. 20 others had the same idea, but the guard let us on, and three hours later we were back in London. An extra 50km to cycle to Ipswich for the main-line trains was thanfully avoided.

img_0404The high point was tearing down the Suffolk Coastal District part in the back of a fast-moving (~35km/h) peloton. The low point was definitely waiting for the rain to clear at Dunwich and dreading the cycle to Ipswich. The most memorable sight was seeing a long stream of flashing red lights in front of me, sweeping around invisible corners.

Despite the pain near the end, it was great fun and good training for when I set off to cycle the length of Britain (Thurso to London) in a couple of weeks time.

We spent a couple of hours taking breaks, including nearly an hour at the 100km feed station. The first 100km was virtually without stopping, but the latter section had more frequent stops, as Michal’s bike started to make strange mechanical sounds and so he limited his speed. We also took a couple of wrong turns later on, although we found straightforward shortcuts back onto the main route. At one point, Michal and I thought Jenn, who was generally the fastest of us three and was ahead most of the time, had missed a sharp turn and headed off to the coast 10km south of Dunwich. However, after a bit of worrying, it turned out she had made the turn after all.

On the back of a disturbed night the night before, and obviously no sleep at all last night, I don’t feel too bad right now. However I did nod off numerous times on the packed train back from Ipswich to London.

Drinks-wise I got through 1 litre of Lucozade and around 1 litre of water, + coffee at the feed station and at the cafe at the end. Food I ate included some chewy sweets, three Power-bars and few Clif Shot Bloks. At the half-way point a had a pasta salad plate and a couple of bananas. At the end I had an SIS sport bar and a Clif bar, as well as the cooked breakfast. As a consequence I didn’t bonk at all and feel fine now!

Battersea Park Race

The second of this summer’s SLOW Park Race Series was last night, at a rather special venue – Battersea Park in south-west London. The last time this area was used for orienteering was at the Sprint finals of the Orienteering World Cup competition in 2005 – if it was good enough for the world’s elite, it was good enough for me!

The park is quite ornamental and I was expecting a run high on dramatic views but short on technicality, however Abi and Matthias planned a excellent Long course which got steadily more technical towards the end – I started making quite a few mistakes after the half-way point, and saw other people making bigger ones. My worst was not reading the control description at No. 14 (it is a sprint area after all!) and going round the Japanese Pagoda rather than up onto its plinth. The hot and humid weather probably didn’t help with the concentration either. There was some excellent long legs allowing for quite a bit of route choice – there’s too much “stuff” in the park to allow running along the leg line, unlike at Clapham Common a couple of weeks ago.

There was a great turnout – over 70 people started the Long course which is definitely a record for this series.

Looking forward to the next one in two weeks in Ravenscourt Park and next week’s Mobile-O (an orienteering race guided by mobile-phone!)

Here’s the map – pic snapped on my iPhone, hence the rubbish quality:

Lambeth Street-O

Lambeth Street-OHere’s my route around Lambeth last night, during the final SLOW Street-O of the series this year. The race was during daylight hours – which was good, as some of the areas around the bottom of the map are not places I would want to be in after dark.

Highlights included the Oxo Tower and the Oval cricket ground – which I failed to recognise on the map until I got there.

I ran 11.5km, in 60:14 – so incurring a 10 point penalty for being late back. I finished fourth, my best result of the series, although Nick and Paul weren’t running, and Mike was demoted to fifth in somewhat controversial circumstances.

More Ascent Goodness

More GPS tracklogs overlaid on high-resolution aerial photographs in Ascent:


1. The Bushy Park Time Trial (5K) route – now going clockwise around the park.


2. A quick (700m) warm-down jog up and down one of the tree-lined terraces in Bushy Park. Notice you can see every tree.


3. Today’s exhausting orienteering race at Woolbeding Common – M21L. Quoted distance was 11.9km, but, per my GPS, I actually ran at least 14.5km.


4. A mistake on the Woolbeding Common race – at number 18 – approaching from the left. It was just after the 12km mark and I was tiring badly, so my concentration went. I swung away from the control too early, and strayed too close to the distinct vegetation change. I only found the control “by luck”, while starting to relocate back onto a path.


5. Finally, from Google Earth, a view of my steep descent from near the summit of Arthur’s Seat in Holyrood Park, Edinburgh, during my orienteering race there last summer.

Urban Orienteering

I’ve been doing a few street orienteering races around London recently. These are generally in the evening, when it’s dark, but I don’t need to geek out with a head torch as street lighting is normally sufficient to be able to read the map. The races are score races – you choose your own route and aim to get as many controls in 1 hour, with stiff penalties for being late back.

Here’s my route from tonight’s LOK event in London’s West End, as viewed in Ascent’s very cool map. The start was actually at the same place as the finish (chequered flag) but my GPS only gained reception after a few minutes of running. My route included an “interesting” stretch along Oxford Street, weaving in and out of the Christmas shoppers, then down Carnaby Street, across Regent Street, and into Theatreland, Soho, Chinatown and Covent Garden, before heading back to the University of London, where the finish was.

West End Orienteering

Another interesting thing – my HR during the race has a distinctive pattern – dipping noticeably every time I stopped at a control. A “control” on a street race like this one, consists of writing down a word you would only know if you were at the correct place, into a box on the back of the map. Examples included the name of the pub in front of you, how many pillars in the church entrance, and Statue of William who? (The Lamb & Flag, 6 and Pitt, in case you were wondering.) Unlike a normal race, where with good “flow” and forward planning you can almost keep running while punching, you generally have to stop for a good 10 seconds to write down the answer. Hence, the noticeable dip, 21 times, corresponding neatly to the 21 controls I visited, and the final dip at the finish. My highest HR, 190bpm, was during a long, straight run, around halfway through, between the two clusters of controls that I visited.

West End HR

Here’s an extract, again from Ascent, for a SLOW street race in suburban Wimbledon, that I ran a few weeks ago. Only part of my race is shown. Here, the colours on the route correspond to the speed I was travelling at. Dark blue is slowest and green is fastest. The blue generally occurs at the points where I’m at a control – I typically make a sharp turn here too, due to my possibly non-optimal route to the next control. I had difficulty finding the plaque on a church in the top-middle of the picture, hence why I was walking (dark blue) around it. Caxton road was on a hill, hence why I’m going fast (green) one way down it. At this resolution, you can see where I crossed each road, and whether I went straight across, or at a diagonal, or even just ran down the middle of the road to avoid slow pedestrians.

Wimbledon Street Race

Ascent is a very impressive program, and is working great so far with my Garmin 305 wrist-mounted GPS and HR monitor.

ps. Altitude estimation is hopeless with GPS – apparently I climbed 1170m in tonight’s one hour race. In fact, the race was completely flat, I probably actually climbed no more than 30m in the entire race. Momentary echos off the high buildings in central London will probably have caused this apparently impressive climbing feat.

Ascent Analysis

Here’s an analysis, in Ascent, of my orienteering today, at the November Classic in the New Forest. See my Attackpoint training details for the race analysis. Click for the full-size version.

The blue line is my altitude. This is pretty inaccurate due to GPS calculations of altitude being inherently flawed. For example, I’m pretty sure I didn’t drop down that low int he first third of the race. However, it is useful as a relative guide.

The red line is my heart-rate – not smoothed. The colours behind it represent my heart-rate zones, so you can see I was in the anaerobic zone for much of the race, but was in the “red line” zone for quite a bit, including at the tops of a couple of the hill climbs, and at the sprint with the finish line in sight at the end. The three bubbles mark the three points where my HR was highest (187, 189 at the tops of the two hills, and 189 at the finish.) Overall I kept my HR pretty constant throughout this race. This was deliberate, I was slowing slightly for the latter half to keep it in my desired range.

The green line is my smoothed speed – averaged over 1 minute intervals during this 82 minute race. I was surprised to see my speed change so much during this race, but I guess this is typical orienteering, with many vegetation changes, on/off track running, and direction changes.

Times when I was standing still – there were a few unfortunately – have been removed.

You can see almost every control – as a dip in my smoothed speed. There’s 21 dips, corresponding to the 21 controls on the course.
