The Run

The Lost Sierra Endurance Run is a 50- kilometer (32- mile) long foot race, highlighting some of the most incredible terrain and scenic beauty the northern Sierra has to offer. And it includes our favorite network of trails in the spectacular Lakes Basin Recreation Area. The racecourse starts in downtown Graeagle, climbs to the crest of the Sierra, skirts the edges of a half-dozen alpine lakes, summits two rugged peaks, and then descends 4,000’ back into Graeagle for the finish.

There are a total of 3 Time Checkpoints (14 miles, 21 miles and 27 miles). To ensure runner safety, and the sanity of our volunteer course marshals, runners are required to pass through designated Time Checkpoints within the limited timeframe, or they will be pulled from the race. Runners that are pulled will be directed to the nearest bail-out location along Gold Lake Highway for pick-up.

For 29K runners, there will be a shuttle to the race start at Round Lake trailhead. The 29K race starts at 10:00AM and racers must be ready for departure at 7:50AM. It is mandatory that racers use this shuttle, as there is no parking at the race start.
