Fleet Feet 20 Miler
About this race
Join us Saturday, October 10th, 2026 for the Fleet Feet 20 Miler! This fully-supported training run is perfect for runners preparing for a Fall half or full marathon. The 20 mile long run is typically the longest and most challenging training run in a marathon training season. This un-timed event has been designed to make that longest run easier and more fun!
Nike will be on site supporting the run with giveaways and demo shoes.
The route will be out-and-back featuring 20 and 10 mile options. We’ll start at Fleet Feet, head to the wonderful South Creek Greenway for a bit of shade, and go west toward the end of the trail. Along the way you’ll encounter fully stocked aid stations and porta-potties.
Join us post-run to refuel with Ott's Pasta.
The first 50 to register will get a Fleet Feet Marathon glove.
