Ann Arbor, MI
This is a Halloween-themed race in Ann Arbor, and the costume element is part of the point. The course is chip-timed with live results, so runners who want to track their splits can. Photos are taken on the course and available afterward at no extra charge.
There are snacks at the finish, and awards are handed out after the race. The event draws a mix of people who are there to race and people who are there for the occasion, and both seem to fit.

The Treat Trot Ann Arbor has been held every year since at least 2026. That is as far back as RunSignup's records for this race go, so it may well be older.

How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 25, 2026.
Set a goal and get a pace band: every mile split on a card sized for your phone lock screen, so race morning needs no math.

Almost certainly not. Half the 3.1 Miles field finished slower than 36:28, and the last recorded finisher came in around 1:06:17, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.
It is a small race (66 finishers), which is friendlier and less intimidating than a big-city event, though the field thins out. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 3.1 Miles, that spread matters more than the winner's time.
The 3.1 Miles winner ran 18:52 while the median finisher took 36:28. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
