The Dusk-til-Dawn mountain bike race in Thetford Forest fully lived up to it's reputation as a grand test of endurance. Those who were still racing after the 12 hours of drizzle, occasionally varied by light rain, will have memories to last a long time.

There were 1000 riders entered – nearly 200 of them attempting to ride solo throughout the night, the rest in relay teams of two, three or four.

The most laps – 15 – were covered by the four man Fenboy Slackers team of Nigel Scott and Paul, James and Shane Ashby.

A combined King's Lynn CC and Wisbech Wheelers of Steve and Dan Collins, Russell Rout and Matt Bukler were fourth in this category.

City College Norwich put in five riders – and won both the pairs and the teams of three, as well as gaining tough experience for their Sports Therapy students who provided services available to all competitors.

Under the Team CCN banner Darren Evans and Jason Smith completed 13 laps of the 10.4 mile circuit based at High Lodge in Thetford Forest with just five minutes to go – and had a tense time watching to see if Wymondham-based Salsa Factory Racing would appear in time to start a 14th lap.

They did not, and the win was Team CCN's. Evans – like most competitors – found disc brake pads were wearing away in next-to-no-time as the bikes ploughed through a grinding paste of grit and sand. But he found that speed could be regulated by riding through mud to slow down, or finding grass to speed up.

Team CCN's Andy Manning, Glenn Stanford and Shaun Aldous were the fastest three-man team with a massive 46 minute margin.

The previous day Cameron Toms had had an outstanding result in the Basildon Cyclo-Cross where he took third place, seven seconds ahead of Iceni Velo clubmate Matt Thurston.

The new heathland course featured three hills, one as steep as 25 per cent. Winner was another star climber – Andrew Nichols (PCA Ciclos Uno).

Further afield, Peter Hargreaves (VC Norwich) took fifth place in the Finsbury Park CC road race in Hertfordshire after helping to form what eventually became a successful ten-man break.
