A: Our most competitive category. Consider it a “Pro/Cat1/2 Race”. All legal race tactics welcome, this is about competing with each other respectfully and pushing each other as hard as we can.
B: Our less advanced competitive category. Consider it a “Cat 3/4" Race. This also encompasses anyone who has a goal to compete beyond what the C race would allow. If people who are just trying racing want to race for less than 45 minutes, they can always drop out early.
