The Matt Mason Memorial "Cowboy UP!" Triathlon & Duathlon was created to honor the life and legacy of Navy SEAL Matt Mason, an American hero who made the ultimate sacrifice for our country on August 6, 2011. This year marks the 15th anniversary of Matt's passing.

Through the generosity of our participants, sponsors, donors, and auction supporters, 100% of proceeds from Cowboy UP are given back locally to support veterans, active-duty military members, first responders, and the families of fallen heroes.

We are incredibly grateful for the amazing auction items that have been donated to help further this mission.

To participate in the Silent Auction, please register first by clicking the blue "Register to Bid" link under the Auction tab. Popcorn bidding is on for this auction. If someone bids in the final 2 minutes, that item’s timer adds 1 minute (so everyone has a fair chance to respond). The timer can extend up to 5 minutes total per item.

Thank you for helping us honor Matt's memory, support local heroes, and ensure that their sacrifices are never forgotten.
