Battling alongside Dartmouth’s John Steel Hagenbuch through the first three laps, Davies turned on the jets in the fourth lap, creating a nearly 40-second gap by the time he returned to the stadium for the final stretch. With the victory firmly in hand, he had the presence of mind—and school spirit—to grab a Utah flag from teammate Claire Timmermann and wave it proudly as he crossed the finish line.

"It's been an incredible journey," said Joe, "and to finish with a national championship is beyond what I could have dreamed of. This team, this school—it's all been such an amazing part of my life."

Though this race marked the end of his collegiate skiing career due to the conclusion of his NCAA eligibility, Davies leaves behind a legacy of excellence and endurance on the Utah Ski Team. His 2025 season was packed with accolades:

  • NCAA First Team All-American (7.5K Freestyle)
  • NCAA Second Team All-American (20K Classic)
  • RMISA/NCAA West Regional Individual Champion (Men’s 7.5K Freestyle)
  • All-RMISA First Team
  • RMISA Skier of the Meet – RMISA Championships
  • Utah Ski Team David Novelle Memorial Award (Outstanding Male Skier)
  • Started eight races this season, all top-10 finishes—including five podiums and two wins

Joe’s achievements are a testament to his drive and dedication, both on the mountain and in the classroom. As he prepares to graduate with a degree in Civil Engineering, his impact on the Utes Ski Team and the University of Utah will not soon be forgotten.
