F60-64: Terri Cassel Runs Away With It at CIM

• Terri Cassel, 63, finished 1st in F60-64 in 3:14:58 (7:26/mi) — a 13-minute gap over 2nd place, the largest margin on the F60-64 podium.
• Elizabeth Shortino (3:27:42) edged Debra Carlson (3:28:43) by just over a minute for the silver spot, with both women finishing within 75 seconds of each other.
• Chiyo Shidara, 63, was the biggest mover in the top five, climbing from outside the top 1,000 women at the start to 940th by the finish — a steady, relentless grind forward.
• 77 women finished in F60-64, with the top 20 all coming in under 4:00.

Terri Cassel of Tulsa made this one look almost comfortable. Running 7:26 per mile across 26.2 miles, she crossed in 3:14:58 and was never seriously threatened in F60-64. Her gender place actually dipped slightly in the back half — from 398th among women at 35K to 405th at the finish — but that's a minor wobble in an otherwise dominant performance. The 13-minute cushion she built over Shortino tells the real story.

Behind Cassel, the race for 2nd and 3rd was genuinely compelling. Elizabeth Shortino of San Anselmo ran a composed race, holding her gender position steady through the middle miles and finishing in 3:27:42. Debra Carlson of Edmond, OK took a different path — she was actually ahead of Shortino through the early checkpoints, posting one of the stronger 10K–15K splits among the women in the group, but faded in the second half as her gender place slipped from 635th to 758th. Shortino's consistency won out, by 1:01.

Fiona Jackson of Vancouver rounded out the podium in 4th at 3:33:39, while Chiyo Shidara — also 63, also from the Bay Area — was the quiet story of the top five. Starting deep in the women's field around 1,073rd, she worked her way forward all day to finish 5th in F60-64 in 3:36:05. The conditions at CIM — cool at 59°F with minimal wind — were about as good as December racing gets, and the depth of this age group showed it: all 20 listed finishers broke four hours.
