Blacktail Climb

Experience the Flathead Valley from a whole new perspective at the Blacktail Climb on October 3rd—a cycling event that blends endurance, elevation, and incredible views. Set against the backdrop of Blacktail Mountain, this mixed pavement and gravel course challenges riders while rewarding every mile with sweeping overlooks of Flathead Lake, crisp autumn air, and vibrant fall color.

Hosted by the Lakeside Somers Chamber of Commerce, this event brings together riders, businesses, and community members in a celebration of both cycling culture and connection.

A portion of proceeds will support Blacktail QRU, helping give back to those who serve this mountain and our surrounding community during the winter season.

With multiple ways to ride—from the full summit climb to a shorter 10K route, plus a laid-back e-bike fun ride later in the day—there’s truly something for everyone, whether you're pushing for a personal best or simply out to enjoy the experience.

The day doesn’t end at the finish line. The Blacktail Climb rolls straight into a lively outdoor after-party at Tamarack Brewing Company, featuring local brews, food, music, and a vendor village. From competitive riders to casual cruisers, this event is all about coming together to ride, connect, and celebrate fall in the Flathead Valley.
