Marathon At The MAC is a self-paced indoor marathon on the MAC walking track. Participants complete 26.2 miles on their own schedule by walking, jogging, or running a total of 208 laps. After each walk or run, participants report their lap count to the MAC front counter staff, so the marathon can be built up over multiple visits.
