Welcome to SpartanNash YMCA Byron Days 5K Run/Walk in Byron Center. The Byron Days 5K has been a signature event of the Bryon Days Festival since 2005. The 5K will start at 8am on Byron Center Avenue just north of Sherwood and Byron Center intersection and wind through the tree-lined Railside Community to Kent Trails before returning to the finish line. Whether you are a runner or an occasional walker, we'd love to see you at the start line! There is also a Virtual 5K Run/Walk if you can't be there race day but want to support the SpartanNash YMCA.
Please register early to be guaranteed a t-shirt. If you register after July 1, we cannot guarantee that there will be a shirt available for you.
Online registration will remain open until the 8am start of the 5K - plan to register on your home computer before arriving or your phone on-site. No onsite computers/tablets will be available to register.
The Byron Days community parade will follow at 10:00 a.m. Our event is held in conjunction with the annual Byron Days Festival in July.

From Endurance Grid
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
Obstacle course races combine running with walls, rope climbs, carries, and mud — testing strength, grip, endurance, and mental toughness all at once.
No two races feel the same, and it is a truly unique endurance sport.
Mud, obstacles, and miles. Raw fitness meets mental grit in a way no other sport matches.
