If you have access to previous races average speed with the same field of racers, you can use that as a guideline with taking in consideration your cadence sweet spot to calculate the gear ratio you want.

Senior elite at Bromont is usually around 43-45kph average speed during mass start races
My cadence sweet spot is 95-105rpm
So i hover between 50/14 and 50/13
