Colville, United States • 13 Jun 2026

Kaniksu Trail Runs is a weekend of mountain trail events organized by Kaniksu Ultras in the Lower Selkirk Mountain Range of the Colville National Forest near Frater Lake, Washington. The weekend includes multiple trail distances, single-track terrain, and several aid stations along the courses. Course GPX files are provided for each distance. Event distances include: - Long Walk 100K - Kaniksu 50 mile (K50) - Sweet 50k (32 miles) - Granite Grinder 26.2 - Tall Trees 29k (about 18 miles) - Herman's Half-ish (about 13.5 miles) - Emory Corwine Memorial Ruck Race relay - Solo Ruck and Blister Club solo ruck - SERE Beer Mile The Long Walk 100K follows the K50 course with an extended section south of Granite Peak, includes Rufus Aid, Taco Aid, and Granite Aid, and is primarily single-track trail with minimal dirt road.

The Kaniksu 50 combines an 18 mile out-and-back that reaches the rocky summit of Granite Peak with a 32 mile loop, and lists 11,100 feet of elevation gain and a 20 hour cut-off. The Granite Grinder is a single-track 26.2 course that also gains the Granite Peak summit before a long downhill return. The Sweet 50k is a lollipop course with about 7,000 feet of elevation gain, multiple aid stations, and a 12 hour cut-off.

The Tall Trees 29k follows the K50 out-and-back to Granite Peak with roughly 2,500 feet of vertical gain and an 8 hour cut-off. Herman's Half-ish is a point to point mostly downhill course with a 5 hour cut-off. The Emory Corwine Memorial Ruck Race is a relay where teams of two to five complete the K50 course legs while carrying minimum pack weights; ruck participants have a 20 hour time limit. Proceeds support the SERE Memorial Fund and the event has donated food to a local food bank.

The SERE Beer Mile is a short loaded and unloaded beverage event held near the Frater Lake start area with specific consumption and penalty rules, and volunteer drivers will be available for competitors. Visit the organization's website for the most recent information.
