Interlaken Ice Cream Dash
The Interlaken Ice Cream Dash takes place on Tuesday, August 4, 2026, at Interlaken Park in Seattle, Washington. The park is a 51-acre forested area between the Montlake and Capitol Hill neighborhoods. The event is part of the Tuesday Night Trail to Grill series.
Distances:
- 5k
- 10k
The course begins with an out-and-back on the paved, car-free Interlaken Boulevard, then climbs via a short staircase onto dirt trails. Runners encounter a few steep pitches and a sustained climb to the top of the park before returning downhill to the boulevard. Each loop measures 2.5 km; the 5k is two loops and the 10k is four loops.
An aid station is located at the start/finish. Five-kilometer runners pass the station at 2.5 km; ten-kilometer runners pass it at 2.5, 5.0, and 7.5 km. Available refreshments include water, Skratch Labs electrolyte drink, and a variety of carbohydrate-rich and salty foods such as cookies, pieces of energy bar, gels, chews, chips, bagels, fruity candy, fig bars, peanut butter and jelly sandwiches, and bananas.
The start/finish is near the intersection of 21st Ave E and E Interlaken Blvd, with street parking adjacent to check-in. Weekday evening traffic and busy park conditions are noted.
Post-race offerings include hot dogs, veggie dogs, watermelon, other snacks, and ice cream. Awards are presented to the top three Female and Open finishers in each distance and there is a raffle. Trails remain open to other users during the event. Visit the organization's website for the most recent information.
