The 66th Mt. SAC Relays wrapped on Saturday evening at Hilmer Lodge Stadium in Walnut, California, closing a four-day elite-and-collegiate programme that ran from Wednesday 15 April through the International Day of Champions on Saturday 18 April. The week-long meet, which traditionally opens with the community-college competition earlier in the month, forms part of the 2026 USA Track and Field Tour and carries World Athletics Continental Tour Silver and Bronze status across its professional events. Organisers welcomed a field drawn from more than two dozen NCAA programmes plus international professional squads from Japan, Kenya, Ethiopia and Great Britain.
The marquee session ran on Friday night with the Distance Carnival, where the elite 5,000m and 1,500m events set the tempo for the weekend's American outdoor distance calendar. The 10,000m and 3,000m steeplechase fields, split across Thursday and Friday, gave NCAA programmes a first major opportunity of the outdoor season to lock in qualifiers for the West Preliminary Round, with a clutch of season bests and a handful of personal records registered in the cooler evening conditions under Hilmer Lodge's floodlights. The meet's signature pacing set-up, which continues to produce more fast 5,000m times each April than any other US collegiate fixture, once again delivered the depth of sub-13:45 men's marks and sub-15:45 women's marks that the event has become known for.
Saturday's International Day of Champions programme added the sprints, hurdles, jumps and throws to the distance story, drawing a Continental Tour-standard field that included two-time Olympic medallists and a strong contingent of sub-13.00 men's 110m hurdlers. The meet's combined men's and women's 4x400m relays closed the afternoon, with traditionally strong showings from USC, Arizona State and Stanford. Arizona State, in particular, had flagged the Mt. SAC Relays as a key mid-season test ahead of the Pac-12 break-up's final Pac-whatever-it-is-now championships on the track, and the Sun Devils fielded a men's and women's squad across eleven events over the four days.
The meet also maintained its USATF Tour designation for the second consecutive year, which underpins the prize structure and the participation of non-collegiate athletes chasing world-ranking points ahead of the domestic outdoor championship cycle. With the season schedule squeezed by the build-up to the Budapest-hosted World Athletics Ultimate Championship later in the northern-hemisphere summer, early outdoor fixtures like Mt. SAC have become more important than ever: sub-event world-lead marks set in Walnut typically survive at the top of the 2026 lists into May, when the big European meets take over the ranking conversation.
For fans, the complete results set is now being posted through the meet's official RunMtSAC and RunnerSpace live portals, alongside TFRRS, where collegiate qualifying performances are verified for the NCAA regional entries. The 67th edition will return to Hilmer Lodge Stadium in April 2027, and organisers have already confirmed they intend to keep the distance-first Friday night format that has established itself, alongside Stanford's Payton Jordan Invitational and the Bryan Clay Invitational, as one of the three mid-April fixtures that together define the American outdoor track calendar.
