Lake Sara Dam Run 5K, 8 Mile & Half Marathon

Lace up for an unforgettable experience at the Lake Sara Dam Run 5K, 8 Mile & Half Marathon, taking place on Saturday, April 4, 2026, in scenic Effingham, IL. This beloved event, often hailed as "The Best 'DAM' Run in Illinois!", offers distances for every runner, from a 3.1-mile 5K run/walk to a challenging 8-mile course and a rewarding half marathon. The races wind along picturesque, all-blacktop routes around Lake Sara, featuring a few rolling hills that provide a moderate challenge and stunning views of the surrounding natural beauty. Typical race day conditions in early April feature comfortable highs around 63°F and lows around 39°F, with a relatively low chance of precipitation.

What truly sets the Lake Sara Dam Run apart is its unique 8-mile distance, a nod to its origins as a fundraiser for the Effingham DUI Taskforce to raise awareness for the 0.08 legal limit. Today, this community-focused event continues its philanthropic spirit, with proceeds benefiting local Special Olympics athletes in Effingham County, Sigel, Neoga, and Arcola, as well as local individuals battling cancer. Runners consistently praise the supportive atmosphere, where Special Olympics athletes often volunteer at aid stations, encouraging participants and proudly awarding medals at the finish line. You'll find water stations approximately every two miles to keep you hydrated.

The race kicks off from 9352 E. Park Avenue, near the iconic Lake Sara Dam, with the Half Marathon starting at 7:00 AM, the 8 Mile Run at 8:00 AM, and the 5K Run/Walk at 9:00 AM. Beyond the camaraderie and beautiful course, participants are treated to impressive race swag, including custom shirts or jackets (for those who register early) and a massive 4-inch finisher's medal, proclaimed as the "Biggest Dam Medal in IL!". Join fellow runners and walkers for a memorable day that celebrates fitness, community, and giving back.
