Welcome to the 2nd annual Weld Your Mettle Ultra Marathon and 7k run, walk or ruck, brought to you by the run.Windsor Race Series. Held on the Poudre River Trail. Connecting Windsor to Greeley, this race will strengthen your resiliency when faced with adversity and challenges.
Big news...We are adding a Heavy Half Marathon to the Weld Your Mettle Weekend. Stay tuned on course details!
We'll also offer a full marathon, and 7k Run, Walk or Ruck (4.35 miles) - in honor of Mental Health Awareness Month and the 70 suicides in Weld County in 2019. 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.
Participants will receive a quality technical shirt, finisher medal, chip timing and special early release of Peculier Ales' "Weld Your Mettle IPA" - brewed just for this event!
