Rider’s Guide

2021 Rider’s Guide
(v21-2/3 – added details to checkpoint aerials, filled in missing rider projection times, cleaner schedule, other minor details).

The Rider’s Guide, for both the 210 and 100-mile races, is your all-in-one guide for racers and support crews. It contains all of the what, when, where, and how (you supply the who and why), including checkpoint locations, convenience stores, gear lists, and rules. You can find almost all of this information on the website or in the race updates, but the guide simplifies it and organizes it in one place. If we have any more changes, we will likely communicate those by race updates rather than updated the guide each time.
