Ancient Lakes Trail Run
Quincy, United States • 10-11 Apr 2027
Ancient Lakes Trail Run
The Ancient Lakes Trail Run takes place April 10–11, 2027 near Quincy, Washington, using trails accessed from the Ancient/Dusty Lakes Trailhead and the Bishop Recreation Area parking. The event offers multiple trail distances over single track terrain and includes on site packet pick up and race day registration if spaces remain.
Distances offered include:
- 50 Mile
- 50K
- Marathon (new for 2026)
- 25K
- 10K
The main course uses a cloverleaf design built from a larger 25K loop composed of three smaller loops that begin and end at a common aid station. The 25K loop has about 2,200 feet of rolling elevation change with no single climb or descent more than 400 feet. The 10K route uses portions of two loops and has about 1,000 feet of elevation gain. The 50K runs the 25K loop twice and the 50 Mile runs it three times. Aid station visit counts and mile markers are provided: 25K hits the aid station twice, 50K five times, marathon follows the 50K pattern to the finish, and 50 Mile eight times.
Additional notes: 100 extra late start spots were added for Saturday 25K and 10K to increase capacity while managing trail congestion. All race registrations are final; refunds and deferrals are not offered. Distance changes are permitted in the registration system up to two weeks before the race. Free weekend camping is available at the start area. Visit the organization's website for the most recent information.
