Norwich cyclo-cross rider Tim Guy moved up to second place in the region-wide Elmy Cycles League after powering to a 37-second win in the Diss CC event at Redgrave.

Guy (Iceni Velo) overhauled early leader Richard Dunnett (Diss CC) and then shook off last challenger Greg Simcock (Team Corley Cycles) on the third of the 11 laps. Former Norwich rider and current league leader Hayden Wood put in some of the fastest laps, but also lost time by twice de-railing his chain, finally taking third place, four seconds behind.

The course followed the continental pattern by including a road section, humps, hedgebanks, planks to be jumped and reverse-camber corners on grass.

The day will probably be remembered as the one when Diss CC's Sophie Holmes won the Under-12s, beating all the boys in the 28-rider field. Holmes, who has been competing in cyclo-cross since she was six, took the lead from Aaron Freeman (Chelmer CC) on the second of eight laps and steadily extended it until she had 43 seconds in hand at the finish,

In the Veterans' race, winner Phil Buick (Iceni Velo) sprung a surprise on rival Bruce Robinson by attacking on a stretch of hard slog over wet grass, rather than where it might have been expected on a technical section. But Buick had in mind the sharp reverse-camber corners that came next, and here he consolidated his advantage.

In cyclo-cross a good deal depends on the frenetic dash from the start to the first corner and Barford rider Jon Periam (CC Breckland) made his best-ever start and built on that to take third place – his highest-yet placing. Another season-best placing went to son Henry, who was 12th in the youth race. Katy Simcock (Hope FactoryRacing) won the women's race where Katie Scotter (VC Norwich, fifth) was first Norfolk finisher.

Next day Simcock was fourth in the Veterans 40+ National Trophy race at Derby while Buick was 15th in the 50+ veterans, and daughters Anna and Imogen 14th and 16th respectively. Star result at Derby was a clear win in the junior race for north Suffolk junior Hugo Robinson.
