Fourmidable 50k 2019 – Film by Award Winner Linda sanders

Sometimes jokingly referred to as “FourMUDable,” this event boasts 6000 feet of climbing through often back-breaking conditions; indeed, it is billed as the most challenging 50k in the picturesque Auburn/Cool area of California. With less than a mile of road at any time, the race begins with the forebodingly-dubbed “Cardiac Hill” — and from there it gets tough.
