Join a first-of-its-kind global journey: 60,000 collective miles through the human circulatory system. Every step raises awareness of circulation, Peripheral Artery Disease, diabetes, limb preservation, and cardiovascular health.
Join the ChallengeOne shared route for everyone on Earth — from the left heart, to the brain, out to the hands, down to the feet, and back through the lungs.
Sync steps from your phone or watch, or enter miles manually. A few steps still count.
Hospitals, clinics, industry, patient groups, family & friends — or walk as an individual.
39 anatomical checkpoints, each with a quick circulation fact from vascular experts.
The walker whose steps cross a checkpoint threshold becomes its Milestone Hero.
The route follows real circulation — here are the first stops.
