About the Southern Illinois 10K, Micro-Marathon, and PeeWee Marathon
The courses run through Crab Orchard National Wildlife Refuge, starting and finishing at the refuge headquarters. Terrain is mostly flat with a few gently rolling stretches, so there is nothing technically demanding underfoot. The surroundings are the draw: wildlife refuge land gives the route a quiet, open character you do not get in a road race through town.
Check-in and race-morning registration open early, before the first wave goes off. There are several distance options, and runners who tackle more than one earn a special award. Light refreshments are out at the finish, and age-group prizes go several deep in each bracket.

The Southern Illinois 10K, Micro-Marathon, and PeeWee Marathon has been held every year since at least 2017. That is as far back as RunSignup's records for this race go, so it may well be older.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Nov 12, 2026.
