Prepare for a harvest season challenge unlike any other at the Speedy Spud 5K and Mashed Potato Mile, taking place on September 26, 2026, in scenic Rexburg, ID. This unique event, organized by Rexburg Races, invites runners of all ages and abilities to test their limits on a distinctive course through Nature Park. The 5K route consists of multiple laps around the park, with the start and finish lines conveniently located near the pickleball courts, offering a flat and accessible terrain suitable for personal bests or a fun community outing. The accompanying Mashed Potato Mile provides a fantastic opportunity for younger runners or those seeking a shorter, spirited dash.

What truly sets the Speedy Spud 5K apart is its one-of-a-kind "eat and run" circuit, designed to challenge both your cardiovascular and gastrointestinal fortitude. As you make your way through each lap of the 5K, you'll encounter "aid stations" featuring Blisters BBQ fries, Bakers Dozen donuts, and Reeds Dairy chocolate milk, daring you to fuel up on spud-themed treats mid-race. This playful twist promises a memorable experience, culminating in post-race prizes and a raffle. Participants can also look forward to receiving a commemorative T-shirt and medal, provided they register by the specified deadline.

As autumn ushers in ideal running weather, typical race day conditions in Rexburg offer comfortable highs around 68F and cool lows near 39F, with a minimal 6% chance of precipitation, ensuring a pleasant racing environment. The Speedy Spud 5K, a relatively new but much-anticipated addition to the local race calendar, promises a festive atmosphere in the heart of Rexburg, inviting runners to embrace the spirit of the season with a dash of fun and a taste of local flavor.
