Shamrock Marathon Men: Allshouse Holds Off a Late Charge to Take the Title

• Addison Allshouse, 20, wins in 2:26:06 (5:34/mi), the fastest in the men's field and nearly four minutes clear of second place.
• Jerry Greenlaw returns to defend his 2025 Shamrock title (2:27:28) but finishes 2nd in 2:30:04 — a remarkable late surge from 4th to 2nd after the 19-mile mark couldn't close the gap.
• Devin Horseman-Guy (2:30:40, 3rd) and Gabriel Loader (2:31:13, 4th) were separated by just 33 seconds, with Loader posting the 2nd-fastest split on the closing 25.2M-to-finish stretch.
• Ethan Renager led the men's field at the opening 5K checkpoint before fading to 5th by the finish in 2:31:25 — a 1:19 swing from 3rd to 5th in the race's final miles.

Addison Allshouse, just 20 years old out of Fort Belvoir, ran a commanding race. He moved to the front of the men's field by the 5K mark, briefly relinquished the lead around the midpoint, then reclaimed it and never looked back. His 5:34/mi average was the sharpest in the field, and he backed it up with the fastest men's split between 5K and 10K — a sign he was pushing hard and early. His winning margin of 3:58 over Greenlaw was decisive in a five-man field that ran closer than the gaps suggest at the sharp end.

Jerry Greenlaw, the 2025 Shamrock champion who crossed that line in 2:27:28, arrived in Virginia Beach looking to go back-to-back. He sat patiently in 4th for the bulk of the race before making his move after mile 19, climbing to 2nd — but Allshouse was already too far up the road. Greenlaw's 2:30:04 is a solid run in humid, breezy conditions, but the title belonged to someone else this year.

Behind them, Devin Horseman-Guy (2:30:40) was the 2nd-fastest man from 5K to 10K and held 3rd throughout the final miles, while Gabriel Loader (2:31:13) made up ground late with the 2nd-fastest closing split of the race. Meanwhile, Ethan Renager — who led the men's field out of the gate — ran 5:47/mi for 5th in 2:31:25, the cost of that early ambition becoming clear as the miles accumulated.
