Interlaken Icicle Dash
The Interlaken Icicle Dash is a trail running event at Interlaken Park in Seattle, WA, held on January 30, 2027. It is the seventh and final event in the 2026-27 Winter Trail Series and offers two race distances.
- 5k
- 10k
Interlaken Park covers fifty-one acres of forest between the Montlake and Capitol Hill neighborhoods. The park features dirt trails, towering trees, and a wide, tree-canopied paved road that is closed to motorized traffic. The paved boulevard was historically a principal bicycle and buggy path and remains used by bicyclists today.
The course begins with an out-and-back section on the fairly flat, paved Interlaken Boulevard, then ascends a short staircase onto dirt trails, climbs to the top of the park, and returns to the boulevard for a short finish. Each loop measures 2.5 km; the 5k consists of two loops and the 10k of four loops.
An aid station is located at the start and finish area and offers water, an electrolyte drink, and a selection of carbohydrate-rich or salty foods such as cookies, pieces of energy bar, gels, chews, chips, bagel, fruity candy, fig bars, peanut butter and jelly sandwiches, and bananas. The aid station is passed at 2.5 km intervals during each race.
Online pre-registration closes January 28. Runners under 20 receive a $10 discount on registration fees. Visit the organization's website for the most recent information.
