M40-44 Rocket City 5K: Marin Dominates in the Cold

• Kristopher Marin won the M40-44 group in 19:26 (6:15/mi) — finishing 2:35 ahead of runner-up Kendall Dock, the largest margin between any two consecutive finishers on the podium.
• The top four were separated by just 3:39 total, then a 2:58 gap opened between 5th and 6th place.
• Closest battle of the day: Brandon Posey (9th) and Brad Rials (10th) were separated by just 3 seconds — 30:15 to 30:18.
• 28 men finished in the M40-44 group, ranging from Marin's 19:26 down to the back of the field.

Huntsville delivered a sharp December morning — 29°F, clear, and a 16 mph wind that made every second of effort count. Kristopher Marin, 43, from Centerville, Ohio, was unfazed. His 6:15/mi pace put him in a different race entirely from the rest of the M40-44 field, and his 19:26 finish wasn't just a win — it was a statement. The gap back to second place was nearly two and a half minutes.

Behind Marin, Kendall Dock (22:01) and Joshua Heroux (22:38) ran a solid podium, with Nathan Campbell (23:05) close enough that the top four felt like a genuine pack — until you look at the clock and realize they were spread across 3:39. Fifth place came in at 23:55, and then the field opened up considerably, with Adam Harrell crossing in 26:53 for sixth.

The most entertaining duel of the morning played out for 9th and 10th, where Yosuke Hayashi and Brandon Posey were locked together all the way to the finish — Hayashi edging it 30:15 to 30:18. Three seconds after 3.1 miles in freezing wind is as close as it gets without a photo finish. Brad Rials finished 21 seconds further back in 11th, rounding out a tight mid-pack cluster before the field spread toward the 40-minute range and beyond.
