Truro's Chris Opie added to his Canary Wharf win seven days ago with a thrilling Tour Series victory in Aylsham on Thursday night, with it extending UK Youth's red jersey lead.

The 25-year-old was dropped with Team Raleigh's Kristian House from a breakaway group, only for the pair to edge their way back lap by lap.

They caught the three leaders with two to go and while House went again in a bid for solo glory, the chasers fought back and Opie's sprint was enough to take the chequered flag – he also took the fastest lap.

With the Tour Series predominantly a team-based event Opie's UK Youth team-mates backed him up as the highest placed team on the night, extending their lead with only the team time-trial and final criterium in Ipswich on Friday night to come.

Golden jersey holder Tom Scully took the first and third sprints over the hour-long race to underline the Team Raleigh man's leadership of the competition, although Madison Genesis' Dean Downing was the highest points scorer on the night – helped by taking sprint two.

The pair, along with Node4's Roman van Uden, completed the breakaway that helped spoil world and Olympic track champion Ed Clancy's chances of a record fourth win in this year's series – a fifth running of the increasingly popular event.

While the men enjoyed blue skies, an earlier downpour made the already tight and technical 1.2km circuit more hazardous for the final round of the Johnson Grand Prix Series – Breast Cancer Care's Penny Rowson went to hospital with a suspected leg fracture leg after hitting the deck.

Sigma Sport's Gabby Day avoided the early spills to breakaway with Natalie Creswick and take the race win – but the final round was all about series leader Hannah Barnes.

Bandaged, patched and stitched after a nasty fall in Tuesday's previous round at Woking, the 20-year-old Towcester rider did all she needed to – staying out of any more trouble – to finish and secure a first grand prix series triumph. Her MG Maxifuel outfit took the coveted team award.
