Course Information

Please note that the course is subject to change due to logging activity currently taking place in the park.

Most of the trails are single track with gently rolling hills, and other parts are flat and wide. Small portions of the course are on pavement. All of the races start with an easy quarter mile downhill on a gravel road followed by a very steep quarter mile climb on a single track trail. After the first half mile, the trails are relatively flat as they follow near the shore of Jenkinson Lake in a counterclockwise direction. There are some technical sections with plenty of rocks and roots.

The 5K course follows the same hiking trail as all other races for the first half of the distance and then makes a sharp right turn onto the horse trail for the return trip, which finishes by running the first half mile of the course backward. The 5K course is marked with yellow ribbons.

The 10K is an out-and-back course that follows the same hiking trail as every longer race and turns around right before the Park Creek bridge at the northeast edge of the lake. The 10K course is marked with pink ribbons.

The 8.5 mile course makes one complete loop around the lake on the hiking trail. The 8.5 mile course is also marked with pink ribbons.

The half marathon follows the same course as the 8.5 mile race and then runs an additional 4.6 mile loop.

The 18 mile course makes two complete counterclockwise loops around the lake. The first loop follows the 8.5 mile course on the hiking trail, and the second loop follows the 9.5 mile horse trail, which sometimes joins the hiking trail for short distances. The second loop is marked with orange ribbons.

The 50K race first follows the same course as the 18 mile race, which has a cutoff time of 12:45 PM. After 18 miles, runners turn around and follow the 9.5 loop clockwise around the lake, marked with orange ribbons. The cutoff time for 27.5 miles is 3:30 PM. A final 3.5 mile loop completes the full distance.

Aid Stations

There are two aid stations located on opposite ends of the lake. One is at the start/finish area, and the other is at the Hazel Creek area. The 5K and 10K races do not reach the Hazel Creek area, so there is no aid station on the course for those distances.

Plenty of refreshments are available at the event center for all runners.

Directions and Parking

From Highway 50, take the Sly Park Rd exit (Exit 60). Go south on Sly Park Rd for about five miles, and turn left on Mormon Emigrant Trail. After passing over a small dam and spillway, there will be two driveways on the left side of the road. Turn into the second driveway leading to the event center and park in the gravel lot. A sign will be posted. Parking is free at the event center.

Race registration and check-in is located inside the event center. The start/finish area is located across Mormon Emigrant Trail from the event center and down a gravel road a little bit. Bathrooms are available at the event center and along the course in the campground areas.
