Senior Jaron Thomas set a personal record on Saturday, one of several impressive performances for the Colorado track and field team at the CU Invite at Potts Field.

CU also swept the top three spots in the men’s 1,500 meters, while freshman Sage Hurta won the women’s 3,000-meter steeplechase in her first time running the event.

“At this time of the year we’re looking for a couple of things,” head coach Mark Wetmore said. “We look for people making progress, marks that will help us on a conference level and people hitting marks that will qualify for the NCAA preliminary round. We got about four or five of the latter today.”

Thomas set a personal record in the 400-meter hurdles with a time of 50.94 seconds. It’s the first time in his career that Thomas has gone sub-51 in the event and he currently ranks among the top 10 in the NCAA West region.

CU actually took the top four spots in the men’s 400 hurdles, with Trenton Stringari finishing second, Kodie Artner third and Isaiah Kaiser fourth.

Zach Perrin won the men’s 1,500-meters with a time of 3 minutes, 47.85 seconds — just four seconds off his personal record. Ben Saarel and Joe Klecker finished second and third, respectively, in the event.

Hurta, from Hamilton, N.Y., who was 40th in the NCAA cross country championships in the fall, clocked in at 10:40.83 in her first steeplechase.

Also for the women, Gabby Scott and Eriana Henderson went 1-2 in the 400 meters and Rajon O’Quinn won the 200-meter dash.

The Buffs won the men’s and women’s 4×100-meter relays, as well as the men’s and women’s 4×400-meter relays. The women’s 4×100 team of Ana Holland, Tashay Brown, Alexandria Peters and Eriana Henderson posted a time of 45.24 seconds that ranks fourth in CU history.

CU’s Duane McClurkin Jr. won the men’s high jump with a leap of 6 feet, 7.75 seconds, while teammates Giancarlo Narvarte and Dionne Taylor Jr. tied for second at 6-6.
