Description

An out-and-back circumnavigation of the Warm Springs arm of Lake Sonoma. Fairly rugged terrain, 84% single track trails. About 10,500 feet of climb. Limited to 300 runners. Nine aid stations, 14 hour time limit. Finisher's jacket, coolmax t-shirt, other cool swag.

Course

The course is 84% single-track trail, 11% dirt fire roads, with the first 2.4 miles on pavement. The trail is consistently rolling with three significant climbs. There is about 10,500 feet of elevation gain and an equal amount of loss over the 50 miles. Trail quality is generally good; there are very few rocks and almost no roots. However, much of the trail is seldom used and so you can expect a lot of leaves and sticks on the trail. There are 12 creek crossings and most (and maybe all) of them will be wet.

Pacers

Pacers are not allowed due to the difficulty of providing adequate aid. C’mon, you can run 50 miles without a pacer!

Refund Policy

50% refund if you withdraw by March 2. No refunds after March 2. Entries are not transferrable.
