The Big Deal at Great Seal

The Big Deal at Great Seal is an ultramarathon event in Chillicothe, OH on May 1, 2027, organized by RunFluent. Multiple distances are offered on a single 20 mile loop course that is largely single track and includes substantial elevation gain.

Distances:

  • 100 mile (five laps of the 20 mile loop)
  • 100k (three laps plus a 2 mile finishing loop)
  • 20 mile (one lap)
  • 5k and youth 5k (single loop)

The 20 mile loop is approximately 95% single track and 5% dual track, with about 3100 to 3200 feet of elevation gain per loop. The first loop includes a climb up Sugarloaf Mountain; later loops bypass that climb. Sections of the loop include two-way traffic across Shawnee Ridge; the course will be marked to indicate direction and two-way areas.

Aid is available at five locations on the loop, including the start/finish, Rocky Road, and Lick Run. Aid stations will provide water, soda, electrolytes, hot food, and snacks. Crew access is allowed at the start/finish (Ireland Shelter) and at Lick Run only. Pacers are permitted for 100k and 100 mile competitors after the first lap; pacers must register and wear a pacer bib and may only join or leave a runner at specified aid locations.

Cutoffs and awards are published for the 100 mile distance, including an overall 36 hour cutoff and a special Golden Goat award for sub 26 hour finishes or for top finishers if no one meets that time. Drop bag, mandatory gear, packet pickup, parking, camping, and refund policies are specified by the organizer. Visit the organization's website for the most recent information.
