Competition Design
We designed, developed and managed the competition elements of all Trimble Chang events. As consultants we have worked with Nike, Bandit, Formula E, 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. A format based on the Red Hook Crit made its debut in the sport of running at the inaugural Bandit Grand Prix in 2025.
The Midnight Half was the first modern urban running alleycat. The format is now widely adopted across the running world.
