LiverMan 100 is back for 2025! It's gonna be bigger and better than ever. We're mixing things up this year: new route and new format, same gnarly challenge, two options and an even bigger party!We're capping this event at 50 people and it will fill up. Register now!
Presented by Happy Worm: LiverMan 100 is a first-of-its-kind off-road triathlon. Born out of a desire to craft a 'misogi' (a year defining challenge), LiverMan 100 is all about pushing boundaries in the gnarliest way. LiverMan is also a celebration of the gift of life and hopes to raise awareness of the power of organ donation. In 2024, we raised over $3,000 for the Chris Klug Foundation who's vision to eliminate the wait for transplantation.
LiverMan 100 is gnarly and it is wild. As an unsanctioned race, racers will need to be generally self-supported. We will have some aid stations with water and light snacks. There is no medical staff. No closed streets or paths. Racers must follow all road laws and be respectful of other people, cars, etc. LiverMan 100 is meant to be a positive, challenging celebration of life, health, and organ donation! Thanks in advance for your enthusiasm and cooperation.
