It's a nine and a bit mile lap with quite a bit of climbing, quite alot of single track and when it rains, several tonnes of sticky mud.
Last year it was very dry and our 4 man teams did about 4 or 5 laps each, including two back to back overnight laps. The hardest part is the lack of sleep I suppose. The NWA team accumulated 18 laps. The winning teams were up in the 30's...
But lap times and numbers aren't really that important as long as you can get around before the mud in 'plasticine woods' swallows you and your bike.
10 man teams probably did maybe 2 laps at most, and spent the rest of the time drinking and heckling, and not necessarily getting any more sleep than anyone else.
Great event whether you are racing, riding or just there to watch and party.
The only rule with the NWA 'No sleep till breakfast' team is that we have to beat the Anglian 'Flatlanders'...
