Broken Arrow 11K M20-29: Maclean Dominates at Altitude

• Thomas Maclean won M20-29 in 54:29 (7:58/mi), finishing more than 4 minutes 24 seconds clear of 2nd place — the largest winning margin in the field's top five.
• Layne Clark and Nicholas Beltran staged the race's closest battle: just 2 seconds separated 3rd from 4th (1:00:36 vs. 1:00:38), with Beltran actually holding a higher men's standing through the middle of the race before Clark edged him to the line.
• Maclean posted the 5th-fastest split in the field on the Olympic Valley East→Snow King segment, underscoring that his lead was built on speed, not just survival.
• The back half of the top 20 compressed tightly: positions 10 through 13 were separated by just 27 seconds across four runners, all clustered between 1:27:38 and 1:28:05.

Thomas Maclean, 23, out of Stanford, CA, turned this into a one-man show. Running at roughly 7,000 feet above sea level — where the air carries meaningfully less oxygen — he still averaged 7:58 per mile, a pace that would be brisk on flat roads at sea level, let alone on a mountain skyrace. His 5th-fastest split on the Olympic Valley East→Snow King leg confirmed he wasn't just managing the course; he was attacking it. By the time the field reached Snow King, the race for the win was effectively over.

Behind Maclean, Lance Jumbeck (58:53) claimed a comfortable 2nd, but the real drama unfolded in the fight for the final podium spot. Layne Clark, 20, from Dry Ridge, KY, and Nicholas Beltran, 29, from Salt Lake City, ran essentially the same race — same average pace of 8:52/mi — but Clark's stronger Snow King→Finish split proved decisive. He posted the 7th-fastest closing split in the field on that segment; Beltran had been ahead of Clark through the Olympic Valley East→Snow King checkpoint but couldn't hold it. Two seconds at the line, after nearly an hour of racing above 6,000 feet, is as close as it gets.

Gage Jarvis rounded out the top five in 1:05:32, a full five minutes back of Beltran, making the gap between 4th and 5th the widest in the top five. With 30 finishers completing the M20-29 race on a clear, cool morning in Palisades Tahoe, the conditions were about as good as high-altitude skyrunning gets — and Maclean made the most of every second of it.
