Big News for 2024!
We are excited to announce we are changing the format of Weld Your Mettle in 2024. We are challenging our community to run 3, 6, 9, 12, or 24 hours as an individual or a relay team. We will have a loop course of 2-4 miles and either yourself or your team will push yourselves to run as many loops (miles) as you can in your chosen time limit. We will continue to have the 7K (4.3 miles) ruck and run, and a 1 Mile Kids Run.
Stay tuned for important details and updates on Weld Your Mettle.
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!
Register by May 16th to ensure you get this year's custom finisher shirt!
