Enticknap has been in holiday mode so was surprised to take first place with 22 minutes 22 seconds ahead of Paul Hickman (22-27).
Ralph Lilley (23-42) was third.
The times were good because of the warm weather but the finishing straight had a tough direct head wind.
Cameron Turner, on a fixed wheel machine, was chuffed with 24-30, 50 seconds off his personal best.
Dominic Eyre (27-17) beat his PB by nearly two minutes, while Andrea Wood rode her first 10-miler in a superb debut time of 28-50.
