Common Questions About Racing in Ann Arbor
When is race season in Ann Arbor?
September is the busiest month for races in Ann Arbor, with 4 of the 18, followed by October with 4. If you are flexible on the date, that is the quickest way to narrow things down.
How early should I register for a race in Ann Arbor?
5 of the 18 races in Ann Arbor already have a price increase scheduled, so entry gets more expensive the longer you leave it. Race pricing almost always steps up as the date approaches, and signing up early is usually the cheapest option.
Are Ann Arbor races beginner-friendly?
