Shamrock Half Marathon M35-39: Williams Wires It in 1:15:48

By MyRace AIMarch 22, 2026
  • Mike Williams (Harrison City, PA) won the M35-39 race in 1:15:48 (5:47/mi), holding his men's standing steady across every checkpoint and finishing 8th among all men.
  • Gregg Jerez closed hardest of anyone at the front, posting the 9th-fastest 20K→Finish split among the men on his way to 2nd in 1:16:33 — a 45-second gap to Williams at the line.
  • Gerard Shaber was the race's biggest mover in this group, climbing from 38th to 15th among the men and finishing 3rd in 1:18:54 — a 2:06 gap back to Jerez, but a statement run built on a 12th-fastest 15K→20K split among the men.
  • Positions 6–8 were a genuine battle: Reid Kidwell (6th, 1:26:29), Jonathan Torres (7th, 1:26:36), and Corey Mullane (8th, 1:26:44) were separated by just 15 seconds across 6:36–6:37/mi pace.

Williams ran a controlled, confident race. He sat 10th among men through the first two checkpoints, moved to 8th by 15K, slipped briefly to 9th, and reclaimed 8th at the finish — never far from that position all morning. His 5:47/mi average on a humid, breezy Virginia Beach day was the standard no one else in the M35-39 field could answer.

Jerez told a different story: he was 16th among men at 5K and worked his way up to 9th by the finish, with that strong closing split doing much of the damage. He didn't catch Williams — 45 seconds is a real margin — but he was clearly gaining ground in the back half. Shaber's surge was even more dramatic in positional terms, going from 38th among men at the opening split all the way to 15th at the finish, his best segment coming in the 15K–20K stretch.

The fight for 4th and 5th was more measured. Arek Hidirsah (4th, 1:22:16, 6:17/mi) also climbed steadily through the field — 46th among men at 5K, 23rd at the finish — while Will Simpson (5th, 1:23:11, 6:21/mi) was far more consistent in position, hovering around 31st–34th among men from start to finish. Behind them, 361 men crossed the line in M35-39, with the top 20 all finishing under 7:10/mi despite the heavy humidity off the Virginia coast.
