Registration for August 6-8, 2021

Registration opens Jan 5, 2021 on UltraSignup. Racers from 2020 have been rolled over to 2021 and have been invited to register and use their full discount. There will be spots available for racers who donated their fees. Any remaining spots will be first-come-first-served. If provincial guidelines after Jan 8 prohibit us from hosting the event, racers will be given a deferral to 2022.
No race day registration. When an event is filled, it will be indicated on the UltraSignup Register pop-up menu. There is a waitlist.
