2025 Registration

---

The thirteenth annual running of the MIDWEST GRAND SLAM OF ULTRARUNNING in 2024 saw eleven finishers.  Who will finish the Midwest Grand Slam in 2025 in the quest to complete four or five of the Midwest's showcase 100 mile trail races over the course of a few months?   Continuing in 2025 will be the flexibility to complete any four of the five races to receive the Midwest Grand Slam of Ultrarunning award.  Runners who complete all five races will be designated "Super Slammers."

If you have read this far, you must be seriously contemplating a run at the 2025 Midwest Grand Slam of Ultrarunning!  Complete the registration form and get set for the challenge of a lifetime! (or at a minimum, the challenge of the year!)   

The Midwest Grand Slam of Ultrarunning registration form must be received by May 15, 2025.  Please be aware that due to race entrant registration limits at the individual events, one or more of the races could reach their registration limits prior to this deadline, so aspiring 2025 Midwest Grand Slammers are encouraged to register early for the events to ensure that registration is available.

As an added bonus, all Midwest Grand Slam of Ultrarunning finishers will receive a complimentary entry to the Stone Steps 50K Trail Race near Cincinnati, OH (stonesteps50k.com).  This is a $55 value, and the opportunity to run a very tough and beautiful 50K trail race as a nice warm down to your Midwest Grand Slam of Ultrarunningexperience!
