From the Organizer
The inaugural Cleveland Space Race is ready for launch 🚀
Join us on Sunday, September 20 for a one-of-a-kind 5K inside NASA Glenn - an exclusive opportunity to run through a restricted research campus that’s rarely open to the public. This unique course will take participants on a tour of the facility, bringing you closer than ever to where innovation and exploration take flight.
Held during Ohio Space Week, this race is all about celebrating curiosity, discovery, and a little fun along the way - so costumes are highly encouraged. And yes… real-life astronauts will be on site.
Registration opens July 15. Your mission includes a themed race shirt, custom finisher medal, and more to be announced.
This is a capped event and will remain open until sold out!
***All participants must be U.S. citizens and are required to go through a brief security check upon entering the grounds***
