M35-39: Riley edges Llano in a sub-5-minute-mile duel at the front

• Jacob Riley won the M35-39 group in 1:05:10 (4:58/mi), holding off Matthew Llano by just 10 seconds.
• Matthew Llano finished 2nd in 1:05:20 (4:59/mi) — a gap of 10 seconds across 13.1 miles in 79°F heat and 20 mph wind.
• Arturs Bareikis claimed 3rd in 1:11:37, a full 6:27 back of the winner — making the podium a story of two tiers.
• Places 8–10 finished within 2 seconds of each other: Juan de Hoyos III (1:19:41), Ansel Wachter (1:19:42), and Kyle Brady (1:19:42).

Jacob Riley came to Chicago and ran the M35-39 group's best race, clocking 4:58/mi across 13.1 miles in genuinely tough conditions — 79°F, 20 mph winds, and low humidity that punished any pace miscalculation. His path to the win wasn't a wire-to-wire cruise: tracking through the men's field, he sat 14th after the early going, climbed to 11th by 10K, and locked in at 10th by the finish. He also posted the 8th-fastest split in the men's field on the 8K–10K stretch, a segment where he clearly found another gear.

Matthew Llano pushed him every step of the way. The Flagstaff-based runner sat just behind Riley through most of the race and delivered the 7th-fastest men's split in the field on the 10K–15K leg — the strongest individual segment split of the top two — but couldn't close the gap that had opened before that surge. Ten seconds at the line, after 13.1 miles in the heat, is about as tight as it gets without being a dead sprint.

Third place went to Arturs Bareikis of Crestwood, IL, who ran a composed 1:11:37 (5:28/mi) and held his position in the men's field steadily from 5K onward, including the 21st-fastest men's split on the 5K–8K segment. His margin over 4th-place Daniel Regalado (1:12:23) was 46 seconds — comfortable enough to call the bronze his own well before the finish.

Down the leaderboard, the race served up one of its most dramatic moments in the fight for 8th: de Hoyos, Wachter, and Brady crossed within a single second, with Wachter and Brady sharing the identical displayed time of 1:19:42. Across a field of 608 M35-39 finishers running in Chicago summer heat, that kind of convergence at the back of the top ten is a subplot worth savoring.
