A Note for the TUFF!

Final routes will be released on the week of the event.  We are giving ourselves the flexibility to tweak the routes in the coming years. Rest assured, there are finalized courses for this year and our permits are in place.

Segments of both routes will be released in the coming months to be sure riders will know what to expect, so keep an eye on our social channels and sign up for the newsletter. We're excited to share what we've put together!

We want to build a TUFF community of Gravel Riders that can take on any event, although this might be the TUFFest. All TUFF riders will be expected to be self-sufficient. This means you will carry all individual items (Nutrition, Hydration, Clothing, ETC) necessary for up to 50 miles at a time. Aid Stations and more information on the course will be released soon.
