Ho, ho, ho! It’s a holiday week, and there wasn’t a lot of racing.
There was, though, the Desert Solstice Track Invitational and some fast times on the clock.

Desert Solstice Track Invitational – Phoenix, Arizona
Men
Charlie Lawrence, already the 50-mile world record holder, arrived to the track targeting a sub-6-hour 100-kilometer finish. That would’ve been a new 100k world record, too. Lawrence missed those marks but came away with a new American record. Among record-eligible courses, it is the fourth-fastest time for the distance ever. Lawrence finished in 6:07:10. That’s only 95 seconds back of Aleksandr Sorokin’s (Lithuania) 6:05:35 world record. **Jim Walmsley’s **former American record of 6:09:26 had stood since 2021.
In the 24-hour race, **Piotr Chadovich **totaled 155.6 miles. That’s the furthest of any American for 24 hours this year.
