Ian Bibby sprinted to third place at the Circuit of the Mendips, taking the lead of the national road series in the process.
Bibby was followed by Holmes in fifth place, as part of a nine-rider group that battled for the race win in the final two kilometres.
In addition to his win at the Lancaster GP, along with seventh at the Klondike GP and 11th at the Lincoln GP, that put Bibby at the top of the points table and into the lead of the national road series.
How the race unfolded:
The predicted fireworks from kilometre zero and up Dundry hill never materialised thanks to an untimely neutralisation of the race, however it wasn’t long before riders were launching their first attacks.
This resulted in two distinct groups of around 50 riders on the road.
The lead group included Bibby, Holmes, Jon Dibben, Rich Handley, Tom Moses and Erick Rowsell.
They had gained over one minute as the race approached the halfway mark, but by the time the race had covered another lap the groups reassembled.
With a large group heading toward a long run-in to the finish, a couple of attacks were made, but the definitive move came on the final climb of Dundry hill.
With 128km complete, Matt Holmes struck out alone. Over the top of the climb he was joined by James Shaw (Swift) and the duo gained an advantage of around 15-seconds.
With just 11km to the finish, Holmes and Shaw worked well together but behind a strong chase group of seven riders assembled.
They included Bibby and worked tirelessly to close the gap. With just two kilometres to go, nine riders were together and heading into the finishing turns.
Third place for Bibby and fifth for Holmes placed them first and second in the national road series standings.
The series continues at the Tour of the Reservoir on June 22-23.
