Icebreaker Indoor Marathon & Half Marathon
A truly unique event, the Icebreaker Indoor Marathon & Half Marathon takes place at the Pettit National Ice Center in Milwaukee. Participants race on a 2-lane track, around the outside of the ice rink - that's a lot of laps! In addition to the full and half marathons, there is a 5K race, and a marathon relay.
This one's pretty straightforward! The course is a 445.2 meter indoor track. Keep running until you have completed your event!
