Nock the Rock Half Marathon

Saturday, June 27, 2020 • Soda Springs, ID • Course Map

Note: The 2020 race is a virtual event. Registration details are included below.

The mountains of southeastern Idaho and the snow-capped peaks of the Bitterroots in the distance form the backdrop at the annual late spring-early summer running of the Nock the Rock Half Marathon, which is open to runners, joggers and walkers.

The race begins on South 3rd Street in Soda Springs, in front of Caribou Memorial Hospital. From there, runners will head west and south, making a long, out-and-back loop along the roads that lie south of Alexander Reservoir, with a long out-and-back stretch along Larsen Road to start off the race.

That’s followed by a run up to the shoreline of the reservoir, and then a a nearly three-mile stretch along 2nd Bridge Road that ends back at the hospital for the race finish.

For kids who aren’t ready for 13.1 miles, there’s also a one-mile run/walk that joins the half marathon, which runs through an elk ranch and features beautiful views as well. Scheduled starting times are 7:30 AM for the one-mile run/walk, and 8:00 AM for the half marathon.
