M50-54: Larios runs away from the field in San Francisco

• Carlos Larios won the M50-54 race in 1:20:06 (6:07/mi), finishing more than 13 minutes ahead of runner-up Nacho Azaceta (1:33:33).
• Larios posted the 25th-fastest split among women on the 5M–10.9M segment — a remarkable benchmark that underscores just how fast he was moving through the middle miles.
• James O'Brien (3rd, 1:36:49) was one of the day's great movers, climbing from 195th to 140th among men over the course of the race.
• Just 26 seconds separated 4th-place Nicolas Herriau (1:42:54) from 5th-place Jeffrey Madynski (1:43:20), with 6th-place Moises Carrasco (1:43:59) only 65 seconds further back — a tight three-way cluster for the bottom of the podium.

Carlos Larios made the M50-54 race his own from start to finish. The North Hills runner's 6:07/mi average on a cool, humid morning in San Francisco was a cut above the rest of the 98-finisher field — his 13:27 margin over second place was no squeaker. Larios's middle-mile strength was particularly striking: his 5M–10.9M split ranked 25th fastest among all women in the race, a number that puts his effort in vivid perspective against the broader field.

Behind Larios, Nacho Azaceta of Wichita held second place in 1:33:33 at 7:08/mi, while San Francisco's own James O'Brien earned third in 1:36:49. O'Brien's race told its own story — he entered the men's field around 195th and steadily reeled in competitors all the way to 140th by the finish line, posting the 115th-fastest split among women on the 10.9M–Finish segment to seal his podium spot.

The battle for fourth and fifth was where the real late-race drama lived. Nicolas Herriau ran 1:42:54 but faded through the back half, sliding from 182nd to 240th among men — a sign that his early pace cost him. Jeffrey Madynski ran the opposite kind of race, moving from 349th to 251st among men and posting a strong second-half split to close the gap to just 26 seconds at the line. Moises Carrasco (6th, 1:43:59) finished less than a minute behind Herriau, making that 4th-through-6th window one of the tightest stretches in the M50-54 results.
