Fat biking has surged in popularity over the past decade, and nowhere is this more evident than in Leadville. With stunning mountain landscapes and groomed winter trails, Leadville has become a premier destination for fat biking enthusiasts.

Its growing reputation helped bring the Fat Bike World Championships back to Colorado in 2024. This year, the event is staying in Colorado for a second year in a row, returning  to Crested Butte (where it all started), marking its 10th anniversary.
