  The Idaho Falls Chukars and Spud Kings are excited to announce the second annual Changing Seasons 5K, taking place on the morning of June 6 at 8:00 a.m.

  The race will begin at the hottest venue in town, the Mountain America Center, and wind through the quiet neighborhoods of Snake River Landing before continuing along the scenic Snake River Greenbelt. Runners will finish at beautiful Melaleuca Field, enjoying the unique experience of crossing home plate—where MLB legends like Billy Butler and Salvador Perez once swung the bat.

  The Idaho Falls Chukars and Idaho Falls Spud Kings have proudly partnered with Special Olympics Idaho to be the benefactor for the race. Special Olympics Idaho believes in the transformative power of inclusion. Every day, they empower individuals with intellectual disabilities across Idaho to discover their strengths, build lasting friendships, and achieve more than they ever thought possible—both on and off the field.
