Course Information

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 pinkribbons.

13M (Half Marathon)
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.

26M (Marathon)
The marathon course makes two complete counterclockwise loops around the lake, followed by one clockwise loop. The first loop follows the 8.5 mile course on the hiking trail, and the second loop follows the 9.5 mile horse trail. The last loop follows the horse trail backward.

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.

18M, 26M and 50K runners

The upper horse trails on both sides of the lake are marked by EID Park Staff with a blue plastic diamonds on trees. This pertains to the second loop run counterclockwise following orange ribbons, and to the 50K runners on the third loop around the lake running a clockwise loop following orange ribbons.

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.
