Fat Dog Backyard Ultra

Event overview

Fat Dog 120 Trail Race is an ultramarathon series held in southwestern British Columbia, Canada. The 2026 race weekend is scheduled for August 7-9, 2026. The primary point-to-point course begins in Keremeos and finishes in E.C. Manning Provincial Park. The route covers about 124 miles with cumulative elevation gain of approximately 26,000 feet (just under 8,000 m). Much of the course follows remote, technical single-track trails that move from valley bottoms into high sub-alpine terrain and panoramic viewpoints. The event uses sections of many historic local trails and passes through provincial parks and a recreation area.

Backyard Ultra, distances and logistics

A separate Fat Dog Backyard Ultra is scheduled for March 14, 2026 in Abbotsford at Exhibition Park. That event follows the certified Backyard Ultra format: runners complete a 6.7056 km (4.167 miles) lap every hour until they fail to finish a lap within the time limit or do not start the next lap. The Backyard Ultra course links Exhibition Park with the Discovery Trail and Clearbrook Park and uses paved, hard-packed gravel and dirt surfaces with no running on roads. Registration for the Backyard Ultra is listed at CAD $175 plus GST and platform fees, is limited to 150 entrants, and has a minimum age of 18 on race day. Prize tiers are published for different lap totals. The Fat Dog organization also notes commitments to trail maintenance, sustainability initiatives, and charitable support.
