This year-round virtual series, based in Henderson, NV, welcomes runners and walkers of all levels to prove their dedication through solo challenges completed on their own terms. There's no crowd or spectator experience here—just you, the road, and the opportunity to demonstrate what you're capable of when you show up consistently and push through challenges ranging from your first 5K to advanced endurance feats like the 4x4x48. Complete your chosen distance anywhere you prefer, submit your proof, and earn an official hand-stamped challenge coin as recognition of your hard-earned accomplishment.
