M40-44 at the B.A.A. 10K: Hiram Cruz Runs Unchallenged in the Heat

• Solo winner: Hiram Cruz, 41, crossed in 45:23 — the only M40-44 finisher on the day.
• Steady pace: Cruz held a 7:18/mi average across the full 10K in 85°F heat and 64% humidity.

The M40-44 group at the 2023 B.A.A. 10K came down to one man: Hiram Cruz of Springfield, MA. With no one else in his age group toeing the line, Cruz had only the clock — and a brutally warm Boston morning — to race against.

Conditions were genuinely demanding. At 85°F with humidity sitting at 64%, holding 7:18/mi for 6.2 miles required real discipline, and Cruz did exactly that, finishing in 45:23.

Note: The source data contains an internal inconsistency — Cruz is listed as a male M40-44 finisher, but the split note references "fastest women's split on 5K→8K," which cannot apply to a male athlete in this age group. That detail has been set aside rather than reported inaccurately.
