The Blacktail Climb returns to Lakeside on Saturday, October 3, 2026, bringing cyclists, outdoor enthusiasts and the community together for a day of climbing, riding and celebrating all things Blacktail.

Organized by the Lakeside-Somers Chamber of Commerce, the event offers three ways to participate: the Summit Climb — 13.5 miles with approximately 3,000 feet of vertical gain; the 10K-ish Climb — 6.2 miles with approximately 1,500 feet of vertical gain; and an E-Bike Fall Fun Ride for those looking to enjoy the mountain at a more relaxed pace.

A portion of proceeds from each registration will benefit Blacktail Quick Response Unit (Blacktail QRU), supporting the local volunteer responders who provide critical emergency services in the Blacktail Mountain area and surrounding communities.

The event is also excited to welcome Hammer Nutrition as an event partner. Hammer Nutrition will be providing endurance products throughout the race to help participants stay fueled for the climb.

And there's a little extra motivation waiting in the swag bags. Blacktail Mountain Ski Area is generously providing every Summit and 10K climber with a complimentary lift voucher for the 2026–2027 season. After climbing Blacktail in October, participants can come back and enjoy the mountain all winter long.

But the day doesn't end at the finish line.

Following the races, riders, families, spectators and the community are invited to stick around for Tamaracktoberfest hosted by Tamarack Brewing Company, featuring live music, awards, good food, better beer and lots of fun.
