Course and features

The primary course is a point-to-point route beginning in Keremeos and finishing in E.C. Manning Provincial Park. Cumulative elevation gain for the full course is approximately 26,000 feet (just under 8,000 meters). Most of the route is remote, technical single-track trail with sections far from road access. The course travels from valley bottoms into high sub-alpine terrain and passes through three provincial parks and one recreation area in southwestern British Columbia. Other race distances use sections of the full route. Route maps and GPX files are available for participants.

Community, partners and sustainability

The race organization performs trail maintenance for the network used by the event. A portion of entry fees is donated to the Run For Water Society. Fat Dog 120 is a Trail Sisters approved race and participates in the International Trail Running Association green program to review and reduce environmental impact.
