No runner had ever run a mile in less than four minutes in the state of Colorado—until now.

In a certified intrasquad time trial on Monday, August 3, Olli Hoare and Joe Klecker, of the newly formed On Athletics Club, became the first two people to ever run a sub-four-minute mile in Colorado, finishing in 3:56:8 and 3:58:4, respectively. This time trial came after only a month of team workouts for the newest pro running group.

Klecker—a standout at the University of Colorado-Boulder, who took second at the 2019 NCAA cross country championships—was the first to sign with the team earlier this summer. On worked to set up the new group around Klecker, considering his input on where the team should be based, who should be the coach, and who else should be on the team.

“[On’s] commitment to this team and to developing top of the line footwear stands out,” Klecker told Runner’s World. “We’ve been going a month and they’ve already sent their product development team out to Boulder, we’ve been on video calls, and they’re listening to what we have to say about the product and team and implementing them. They just rolled out their first spike, and we used their new carbon shoe on the track [Monday night], not the one on the market so far.”

The group is coached by three-time Olympian Dathan Ritzenhein, who retired from pro running earlier this year. Ritzenhein moved his family from Michigan to Boulder, Colorado, to take on the coaching role.
