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 Jul 27, 2026.
2 of the 3 races in Collinsville already have a price increase scheduled, so entry gets more expensive the longer you leave it. Race pricing almost always steps up as the date approaches, and signing up early is usually the cheapest option.
