Trail Run At Sly Park - Summer
Pollock Pines, United States • 22 Aug 2026
Event Overview
This trail running event is held in the Sly Park Recreation Area near Jenkinson Lake in Pollock Pines, California. It takes place under a special use permit with the El Dorado National Forest. The event features multiple distances on trails that go through pine trees and around the lake.
Distances & Course
Seven race distances are offered:
- 5K
- 10K
- 8 Mile
- Half Marathon
- 17 Mile
- Trail Marathon
- 50K
All races start at the Scales Parking Lot (also called the Equestrian Parking Area). The 5K is an out-and-back course that starts and finishes at this lot. All other distances start at the Scales Parking Lot but finish at the Waterfall Trailhead. After finishing, runners for distances over 10K must walk back approximately 0.3 to 0.5 miles to the Scales lot to reach their vehicles.
The course consists mostly of single-track trails with gently rolling hills. Some sections are flat and wide, with small portions on pavement. The race begins with a quarter-mile downhill on a gravel road, followed by a steep quarter-mile climb on single track. After this, the trails are relatively flat as they follow the shoreline of Jenkinson Lake in a counterclockwise direction. There are technical sections with rocks and roots. Different distances involve various loops around the lake, using both hiking and horse trails.

The event has a cap of 100 runners per day. Registration opens on race day at 6:50 AM at the Scales Parking Lot, with a trail briefing at 7:45 AM. An overall time limit of 9 hours is enforced, with specific cutoffs for each distance.
