The Butler County Donut Trail is an attraction in southwest Ohio which connects 12 (plus one optional) donut shops. If you go to all locations you can get a "passport" stamped and receive a free donut trail shirt. Typically, this is done by driving to each donut shop over the course of several weekends and acquiring a stamp from every shop. However, for this FKT the goal is to run between all 12 primary donut shops, eating one donut per stop, all within one push (i.e. one day).

This route is circular in nature so you can start at any point, most commonly it would be started at the racecourse. It takes you around the outskirts of Cheltenham, going through some of the most iconic and popular running/walking routes. There are plenty of amazing viewpoints of the Cotswolds along the way. It's a mixture of trail/fields and road with most of the road sections being short portions in order to connect to the next chunk of trail. It is waymarked, but many of the signs are quite faded, especially in the busier parts of the trail.
