Olympic Mountains Trail Races

The Olympic Mountains Trail Races are held in the Olympic National Forest between Quilcene and Sequim, on the Olympic Peninsula, and run out of a retired quarry the organiser calls Goat Quarry. There is no street address. Mountain Peaks Racing, a two-person outfit from Kingston, Washington, puts on a 100K and a 50K on the Saturday plus shorter races and rucking divisions, where entrants carry at least twenty pounds over the same courses.

The 100K is the flagship: 62.65 miles and 14,300 feet of climbing on mostly singletrack, run continuously rather than in laps, with a 21-hour limit that a finish inside makes a Western States qualifier. The 50K takes in the two big climbs of the range's northern end, to the wilderness boundary on the shoulder of Mount Townsend and over the summit of Mount Zion, and holds a 14-hour limit that applies to runners and ruckers alike.

Both races start and finish at Race HQ in the Olympic National Forest, twelve miles from the nearest street address. The 100K is 62.65 miles with 14,300 feet of climbing across ten aid stations, described by the organiser as a continuous course rather than an out-and-back or a set of loops, with very few repeated sections. The 50K is a single loop of 31.7 miles with 8,600 feet of climbing, over the shoulder of Mount Townsend at about 5,800 feet and the summit of Mount Zion at 4,274. Sunrise on race morning is after six, so the 100K's 5 a.m. start needs a headlamp.

Open sign-up on UltraSignup, with no lottery, no application and no qualifying standard. Registration for 2026 opened in the new year and closed on August 11, at $225 rising to $255 for the 100K and $125 rising to $155 for the 50K, before tax and fees. There are discounts for tribal members and for serving and veteran military, and a code that takes 20% off a Sunday race for anyone racing on the Saturday. Withdrawals are met with a credit toward the following year rather than a refund. The race also pays prize money in the 100K, which was doubled for 2026.
