George Pym and Lyndsey Glazier took the top honours in the Barnstaple Criterium last night.
Hundreds of people lined up along the barriers to watch exciting floodlit bike racing around the town centre.
And they cheered as Pym, the 19-year-old from Exeter, won a sprint finish to claim the men's elite title.
Representing Spin-Rotor Primal, he was part of a four-man breakaway with team-mate James Williams, Adam Brittain, from High Wycombe Cycling Club, and James Lowsley-Williams, of Team UK Youth.
As the race wound up for a last-lap battle, Pym pulled clear over the final 50 metres with Lowsley-Williams taking second and Williams, last year's winner, in third.
Glazier, representing Team Hope Factory Racing, prevailed in a similar sprint finish to take the women's title.
The 20-year-old Plymouth rider had the power to edge clear of Claire Elworthy, in second, and third-placed Elena Bremer, who were both riding for Exeter Wheelers.
Five races were staged around the town centre, attracting the top talents from the South West and beyond.
The men's category 3 and 4 race was won by Dexter Hurlock, from Plymouth.
Starting with three youth races from 6.20pm, crowds gathered along the Strand and the High Street for almost four hours of racing.
