Welcome to the 2nd annual Weld Your Mettle Ultra: 50K, Heavy Marathon, Heavy Half Marathon, and 7k run, walk or ruck, brought to you by the run.Windsor Race Series. This year we've added Relay Options to the Full and Ultra- meaning you can run this in groups, at approx. 5 miles per runner! Held on the Poudre River Trail. Connecting Windsor to Greeley, this race will strengthen your resiliency when faced with adversity and challenges.
All distances are "heavy", meaning longer than traditional distances, in honor of our ability to go a little further and show how we Weld Our Mettle. Proceeds benefit the local nonprofit Health4Heroes, providing a supportive community, connection, and encouragement, paired with direct, affordable access to local health & wellness services for veterans, first responders, and their families.
Entry into this race is more than a one day event. It's an invitation to change your life, challenge your excuses, dig deep and WELD YOUR METTLE.
