Eddy Trail Races

Eddy Trail Races are a weekend of races based at Chi Rho Center on the south side of Lake Sylvia, on the outskirts of Annandale, MN. The 50k and a half marathon will run through the Stanley Eddy Park Reserve, a wonderful series of trails in our nook of the state.

The main race goal of Eddy Trail Races is to run through Stanley Eddy Park Reserve and Big Eddy does loops through each of the parks, as well as running the roads that connect the parks and Chi Rho Center. There is 1 main aid station that you will run by 6 times and 3 other aid stations that you will run by 2 times each. 12 aid stations over the course of 32 miles so you are never far away from support if it's needed.

The course is closer to 51 or 52 kilometers than 50, but we won't tell anyone if you don't ;).

Cross the finish line and jump in the lake when you're done!
