Rocket City Half Marathon F55-59: Clarke Edges O'Shea in an 11-Second Thriller

• Sia Clarke (55, Mukilteo, WA) won the F55-59 age group in 2:02:00 — a 9:18/mi pace — edging Kiku O'Shea by just 11 seconds.
• O'Shea actually held a better position among women at the 8-mile mark (68th) before fading to 74th; Clarke moved the other direction, climbing from 74th to 73rd among women to seal the win.
• Denise Murphy claimed 3rd in 2:09:04 — nearly seven minutes back — with a clear gap to the rest of the podium.
• The field of 28 in F55-59 spread across nearly 52 minutes from Clarke's 2:02:00 to the final listed finisher.

The headline of the F55-59 race is those 11 seconds at the top. Clarke and O'Shea ran virtually identical first halves — their average paces differ by just one second per mile — but the final stretch told the story. O'Shea had actually carved out a stronger position among the women through 8 miles, sitting 68th compared to Clarke's 74th. Then came the 8M-to-finish segment: Clarke posted the 69th-fastest women's split on that closing stretch, while O'Shea slipped to the 82nd-fastest. That swing of 13 places in the women's field translated to exactly 11 seconds on the clock and the age-group title.

Murphy's 2:09:04 locked up the podium with a comfortable cushion over 4th-place Teresa Hagood (2:11:33), and both women from Madison and Athens, AL held steady across the back half. Gina Thompson rounded out the top five in 2:15:22, with Anne Coia (2:16:01) and Carla Hampton (2:16:57) close behind to make the 5th-through-7th spots a genuine cluster within about 90 seconds.

Further back, Melonie McBrayer and Liz Losole — both from Birmingham — crossed in 2:26:44 and 2:26:46 respectively, separated by just two seconds for 10th and 11th. A cool, mild December morning in Huntsville kept conditions manageable throughout, and all 28 finishers in F55-59 made it across the line.
