Lora Turnham and Corrine Hall continued their dominance of the 2014 UCI Para-cycling Road World Cup with a convincing time-trial victory in Segovia, Spain.
The duo set a time of 29:12.60, 12 seconds clear of Japan’s Yurie Kanuma and Mai Tanaka over 22 kilometres on a flat course in Cuellar.
The victory for the reigning world champions extends their overall world cup lead on the first day of final round.
Paralympic champion David Stone won bronze in the men’s T2 time-trial over 11km.
Stone was ousted by German rival Hans-Peter Durst whose time of 17:17.46 on the trike was nearly a minute faster than the Briton’s 18:16.73. American Steven Pearce was second in 18:01.10.
Karen Darke completed Britain’s medal haul for the day with bronze in the women’s H3 time-trial, adding to her gold in the event at May’s first round in Italy.
American Alicia Dana was fastest in 18:34.29 with Darke 22 seconds back in 18:57.17. Poland’s Renata Kaluza came second.
In the men’s C5 time-trial Britain's Jonathan Gildea was eighth.
Rik Waddon took seventh in the men’s C3 time-trial with teammate Shaun McKeown 12th.
Simon Price was sixth in the men’s C2 time-trial and Brian Alldis 20th in the men’s H4 time-trial.
Tandems and hand-cycles will race on Saturday in Cuellar on a predominantly flat course while Sunday will see action move to nearby Cantimpalos, for the C1 to C5 and trike road races.
The three-day meeting counts towards Rio Paralympic qualification as well as acting as preparation for the para-cycling road world championships in August.
