The Big Deal At Great Seal

The Big Deal at Great Seal in Chillicothe, Ohio at Great Seal State Park unveils an expanded endurance festival for May 2, 2026. New this year is the Big Deal 100 Miler, 100k, 20 Miler, plus Adult 5k and Youth 5k. The centerpiece is a 20-mile loop run entirely on single-track trails with just two road crossings, delivering roughly 3,000 feet of elevation gain per loop.

The event marks three years at Great Seal and aims to offer a bigger, tougher challenge for ultrarunners through scenic hills and a demanding course. This challenging course tests endurance in a forested setting. Visit the organization's website for the most recent information.
