M50-54 at Shamrock: Ko Runs Away from a Deep Field in Coastal Heat

• ByoungGu Ko (53, Alexandria) won M50-54 in 3:09:02 — a 7:13/mi average that put nearly six minutes between him and runner-up Peter Madden.
• Peter Madden (52, Utica) held second in 3:14:57, with Alexandre Deur (51, Yorktown) another two minutes back in third at 3:17:10 — the podium was spread across eight minutes total.
• Raul Ruiz and Donald McKinnon both clocked 3:46:40 for 15th and 16th — same time to the second, different places decided by the finest of margins.
• 76 men finished in the M50-54 group on a demanding day: 71°F, 73% humidity, and a 17 mph wind off the Virginia Beach coast.

The conditions were no joke — heat and humidity at that level can add several minutes to a marathon, and the wind was a constant factor along the coastal course. Against that backdrop, Ko's 7:13/mi average stands out as a genuinely strong performance. His race unfolded with some movement through the men's field, and his split from 5K to 10K was among the faster ones of the day. He crossed in 3:09:02, and by the finish, the gap to Madden was 5:55 — a comfortable margin that suggests Ko had the race well in hand through the back half.

Madden ran a controlled 7:26/mi to hold second throughout, his position in the men's field staying remarkably consistent from the halfway point onward. Deur, in third, had a tougher second half — he was moving up through the men's field early but gradually slipped back as the race wore on, ultimately settling at 3:17:10. Michael Gisonda (54, Boca Raton) and Mark Njore (51, Dumfries) rounded out the top five within seconds of each other — 3:22:52 and 3:23:21 — with Gisonda making a notable move in the final stretch after running conservatively early.

The mid-pack told its own story. Daniel Landry, Kevin Davenport, Gregory Booth, and David Webb stacked up in a tight cluster from 6th through 9th, separated by just over two minutes across four finishers. Further back, the identical finish times of Ruiz and McKinnon — 3:46:40, split only by the timing chip — was the kind of photo-finish subplot that makes a 76-man age group worth watching all the way to the end.
