The leading espoir in last year's series, Jack Green (VC St Raphael) secured victory in the senior category at round five of the RTTC National Time Trial Series in Worcestershire on Saturday.
The 21-year-old from Cheadle Hulme near Manchester clocked 1-16-29 to win the 32-mile two-lap event near Great Witley, more than a minute quicker than his nearest rival.
Green placed third in last year's senior Series, and has not featured on the podium of this year's event. But his time was 1-16 quicker than runner-up at Great Witley Tom Ward, another espoir riding for Team Echlon-Rotor, while Dean Robson (Somerset RC) was third, another four seconds off the pace.
Notching up her third win in four rounds (the first round was snowed off in March), Rebecca Slack (Look Mum No Hands!) was fastest of the women over the one-lap course, clocking 40-47 to win by 1-02 from Bronwen Ewing (Trainsharp RT).
Elsewhere Matt Bottrill - who had won rounds two and three of the series - was in fine form in the Burton and District CA 50 at Etwall in Derbyshire.
The newly-crowned national 50-mile champion, Bottrill set a new personal best and broke the course record for the A50 course, clocking 1-06-45 to win by more than four minutes.
At times Bottrill's speed topped 41mph, and he pushed Charles Taylor (South Pennine CC) into second spot by 4-17, while Tejvan Pettinger (Sri Chinmoy CT) was third, another ten seconds off the pace.
Former National 50 champion Michael Hutchinson (In Gear-Quickvit RT) was in action in the Finsbury Park CC 25 on the F1 course at Tempsford in Bedfordshire, and he took a comfortable victory with a time of 48-42 despite a strong headwind from the turn.
There was a dead heat for top spot in the Withington Wheelers 10 at Monks Heath in Cheshire, with the promoting club's Darren Mairionis and David Crawley (Fibrax-Wrexham) both clocking 20-31.
Rapha Condor CC's Adam French clocked 19-44 to win the Eastern Counties CA 10 at Six Mile Bottom in Cambridgeshire, making the most of better conditions for the later starters after heavy rain and wind blighted the earlier riders.
Martyn Lewis led a one-two for Cyclelogic.co.uk in the St Austell Wheelers 10 in Cornwall. He clocked 21-55 to take the win by 25 seconds from team-mate Drummond Masterton.
Over longer distances, Gary Dighton (Poole Wheelers) won the Bournemouth Jubilee Wheelers 50 at Lytchett Matraverts in Dorset.
He clocked 1-52-46 to win by around four minutes from the promoting club's Jon Clemas, while Terry Icke (Poole Wheelers) took third, just 16 seconds off the pace.
RAF CA rider Justyn Cannon won the Cardiff 100 Miles RCC 50-mile event near Abergavenny on Sunday, clocking 1-47-50 to win by three and a half minutes from veteran Dursley RC rival Derek Smetham.
And in the Shropshire CCA four-up 50km event at Edgmond in Shropshire, in was the Stourbridge Velo quarter of David Mole, James Jevons, Scott O'Neill and Mark Hammond who took victory.
They clocked 1-08-13 to win by 50 seconds from North Shropshire Wheelers, while Preston CC placed third, another 15 seconds back.
