Pi Day 5k: a 3.14 Miler 2027

The Pi Day 5k: a 3.14 Miler is a 3.14-mile run or walk at Rolling Hills County Park in Ypsilanti, Michigan, held for Pi Day. Epic Races presents it as Michigan's Original Pi Run, with the distance matching the first three digits of pi instead of the standard 5K length. The course uses a specially designed circular loop, so the route plays into the pi theme as much as the distance does. Runners and walkers share the event, and the finish leads into a post-race party with complimentary pie and refreshments. Each participant gets a commemorative Pi Run shirt and a finisher medal, with early registration used to lock in shirt size.
