SF Half Marathon F60-64: Callahan Claims the Crown by Five Seconds

• Diana Callahan (Santa Rosa) won F60-64 in 1:42:39 (7:50/mi), holding off Katelyn Johnson by just 5 seconds.
• Katelyn Johnson (Alameda) surged from 144th among women at the 2-mile mark all the way to 80th by mile 12, posting the 49th-fastest women's split on the 6M→8M segment before finishing 2nd in 1:42:44.
• Madeleine Todd and Debbi DiMaggio ran a tight battle for 3rd and 4th, finishing in 2:05:25 and 2:05:49 respectively — a 24-second gap after 13.1 miles.
• 29 women completed F60-64, with the field spread across more than an hour of racing from front to back.

Diana Callahan and Katelyn Johnson put on the race's most gripping duel in F60-64. Callahan held a steadier position in the women's field through the first half, sitting 68th among women by the 6-mile mark. Johnson, meanwhile, was on a completely different trajectory — she entered the race checking in at 144th among women and spent the entire first half hunting her way forward. By the 6M→8M stretch, where she posted the 49th-fastest women's split in the field, Johnson had closed into the top 90 among women and was clearly running the faster leg of the race. What's remarkable is that she nearly erased the entire gap — but Callahan's early cushion proved just enough. The finish times read 1:42:39 and 1:42:44, a five-second separation that belies how much ground Johnson made up. Both women averaged 7:50/mi for the morning, but the race itself was anything but even — it was a catch-up story that came within a handful of strides of a different outcome.

Behind them, Madeleine Todd and Debbi DiMaggio staged their own quieter contest for the final podium spot. Todd (SF) crossed in 2:05:25 at 9:34/mi, with DiMaggio (Oakland) right behind at 2:05:49 — 24 seconds back after 13.1 miles through San Francisco's characteristically demanding terrain. Theresa Woo (Oakland) rounded out the top five in 2:16:03, finishing with the 628th-fastest women's split on the 12M→Finish segment and showing a strong close to her race. Andi Eggers (Emeryville, 2:25:03) and Robin Workman (SF, 2:29:57) filled out positions six and seven, with 13 more finishers stretching the field all the way to Karen Weisman's 3:00:35 in 20th — a 29-woman field that covered every minute of the San Francisco morning.
