New for 2023

We are returning to the 2022 race route once again for 2023, beginning near Keremeos, BC (original startline) and finishing at Lightning Lake day use area, Manning Park, BC (original finishline).  For complete route details, see our routes and maps page.

The 70 mile distance has been re-named the 100 km to better reflect the actual distance of the course. 

We will not be offering the relay option this year.

We have started a "Fatdog 2023 Racers" Facebook group to help racers connect.  This is the place to ask questions, arrange carpools for crew and pacers, share accommodations etc.
