M50-54: Lhamzi Runs Away from a Deep Field at Boston

• Mustapha Lhamzi won the M50-54 age group in 2:29:41 (5:43/mi) — nearly six minutes clear of runner-up Gustavo Campiz (2:35:28).
• Campiz and Martin Sirois staged a fierce duel for second, separated by just 11 seconds (2:35:28 vs. 2:35:39) after Sirois clawed back ground in the final miles.
• Juan Carlos Cardona ran the first half aggressively — entering the men's field as high as 410th — before fading to 5th in 2:37:26, while Robert Rognli ran the opposite race, steadily climbing from 881st to finish 4th in 2:36:20.
• A stacked age group of 1,868 finishers saw 11 men break 2:42 and the top 20 all come in under 2:45.

Mustapha Lhamzi didn't just win the M50-54 age group at Boston — he dominated it. Running 5:43 per mile across 26.2 miles in 51°F conditions, he crossed in 2:29:41 and was never seriously threatened. His moves data tells a story of a man who went out hard and held on: he was as high as 149th among the men at the first checkpoint before settling back through the middle miles, ultimately finishing 293rd in the men's field. That's a remarkable position for a 50-54-year-old in a race as deep as Boston.

Behind him, the real drama was in the battle for the podium. Gustavo Campiz (New York) and Martin Sirois (Quebec) ran essentially parallel races — both averaging 5:56/mi — but Sirois came from further back. Sirois was outside the top 1,000 among men at the opening checkpoint and worked his way steadily forward all day, posting the 409th-fastest split in the field on the 24M-to-40K stretch to close the gap. He couldn't quite catch Campiz, but 11 seconds after 26.2 miles is about as close as it gets without being a tie.

The two contrasting races of the day belonged to Cardona and Rognli. Cardona (5th, 2:37:26) went out near the front — 410th in the men's field early — and paid for it, sliding back to around 944th before recovering slightly to the finish. Rognli (4th, 2:36:20) did the opposite, sitting 881st early and grinding forward checkpoint by checkpoint to pip Cardona by over a minute. Patience, in Boston's famously punishing back half, proved the smarter strategy.

Further down, the depth of this age group is striking. Michael Wardian (Virginia) — one of ultrarunning's most prolific competitors — slotted in 11th in 2:41:00. Six men finished within a 20-second window between 12th and 16th place (2:42:00–2:42:20), making that stretch one of the tightest clusters of the entire age group.
