Rocket City Marathon F45-49: Jenny Dyer Runs Away with It in the Cold

• Jenny Dyer wins in 3:28:58 (7:58/mi), nearly 12 minutes clear of runner-up Angela Harrison — a dominant margin in a 52-woman F45-49 field.
• Closest battle of the day: Jessica Arnette (3rd, 3:43:44) and Paige Dorr (4th, 3:43:45) — separated by a single second after 26.2 miles.
• Arnette and Harrison both closed hard: Arnette posted the 55th-fastest women's split on the final 20M→Finish stretch, Harrison the 54th-fastest on the second half — two late surges that reshuffled the podium order.
• Dorr faded in the back half: she ran as high as 53rd among women through the first 10K, but slipped to 60th by the finish — just enough to hold off Arnette's charge by that razor-thin second.

Twenty-nine degrees, a 16 mph wind, and clear skies greeted the F45-49 field in Huntsville on Sunday — conditions that reward the disciplined and punish those who go out too hard. Jenny Dyer, 48, from Franklin, TN, was disciplined from the gun. She moved steadily through the women's field — from 42nd among women at the 10K to 35th at the finish — running a composed 7:58/mi average and adding the 26th-fastest women's split on the final stretch to close it out convincingly. Her winning time of 3:28:58 was the class of the age group by a wide margin.

Angela Harrison of Nashville ran a strong, progressive race of her own, climbing from 70th among women at the 10K all the way to 55th by the finish — her 54th-fastest women's second-half split reflecting a runner who genuinely warmed into the cold morning. She crossed in 3:40:47 (8:25/mi) to take second, 11:49 back of Dyer.

The real drama unfolded one step behind her. Jessica Arnette of Alpharetta, GA, started conservatively — 78th among women at the 10K — and then turned in the 55th-fastest women's split from mile 20 to the finish, rocketing from 71st to 59th in the women's field over those final miles. That surge nearly swallowed Paige Dorr whole. Dorr, of Trussville, AL, had run a confident early race, sitting 53rd among women through the first 10K, but faded steadily through the second half. She held on — barely — finishing in 3:43:45 to Arnette's 3:43:44, one second the difference between third and fourth place after 26.2 miles in the cold.

Lucy Szlembarska (5th, 3:48:47), Jenny Zarichnak (6th, 3:50:37), and Denise Lanahan (7th, 3:53:13) rounded out the top seven, with the field stretching back through 52 finishers who all earned their medals on a genuinely tough December morning.
