Competition Design
David Trimble designed, developed and managed the competition elements of all Trimble Racing events. As a consultant he has worked with USA Cycling, Italian Cycling Federation, UCI, USATF and the FIA.
The Red Hook Criterium was the world’s first fixed gear criterium. The format and rules set the standard and were adapted for all subsequent fixed gear criteriums.
The Midnight Half was the first modern urban running alleycat. The format is now widely adapted across the running world.
