COVID-19 PRECAUTIONS – We hope our cycling community has stayed healthy, happy and has adapted through these unprecedented times. We are fortunate since our limited field of just 50 riders gives us great flexibility when hosting the event. If necessary, our group rolling start will be broken out into waves of riders during the 6:00-7:00 am time slot to ensure social distancing. Masks will be worn at the start and at all aid stations. Aid stations have historically never had more than a few riders at a time however we will make necessary adaptations with food and fuel distributed by our volunteers with no community style distribution. We will also continue our historical practice of providing all fuel and liquids in sealed packaging and bottles as a best practice.

REGISTRATION DEFERMENT – If the event is unfortunately cancelled, 100% of your registration fee will be transferred to the 2022 Event.
