Rio Del Lago 100 F30-39: Lindsey Dwyer Dominates from the Front

• Dwyer wins in 15:51:34 (9:31/mi), finishing nearly 1 hour 47 minutes ahead of the runner-up in the F30-39 field.
• Anonymous Athlete (Mill Valley, CA) claimed 2nd in 17:38:04, posting the fastest women's split on the Beals Point→Willow Creek segment along the way.
• Samantha Bear made one of the day's boldest moves, climbing from 10th among women at the first checkpoint all the way to 4th — where she held firm to the finish.
• Anna Yip rounded out the podium in 3rd (17:50:50), separating herself with the 2nd-fastest women's split on the No Hands→ALT segment.

Lindsey Dwyer, 34, from Larkspur, ran Rio Del Lago like a woman with a plan and the legs to execute it. She opened with the fastest women's split on the Granite Beach→Rattlesnake Bar stretch and, aside from a brief dip to 2nd among women at the first checkpoint, led the women's race from essentially start to finish. Her 9:31/mi average over 100 miles in 72°F heat is the kind of number that doesn't need embellishment — she crossed in 15:51:34, a margin that turned the F30-39 contest into a race for the remaining podium spots well before the final miles.

Behind her, the battle for 2nd and 3rd was tight and compelling. Anonymous Athlete from Mill Valley held 1st among women briefly in the early going before settling into 2nd, a position she never relinquished. Her fastest women's split on the Beals Point→Willow Creek leg showed she wasn't just hanging on — she was still racing. Anna Yip, the youngest on the podium at 30, was steady throughout, sitting 3rd among women from the early checkpoints and backing it up with the 2nd-fastest women's split on the No Hands→ALT segment to finish in 17:50:51.

The most dramatic story in the F30-39 group belonged to Samantha Bear. Starting 10th among women, she had already surged to 4th by the second checkpoint and locked it in for the remainder of the race — a sustained, patient charge that earned her 4th in the age group at 19:05:51. Further back, all 21 finishers in the F30-39 field completed a 100-mile course in clear November skies — a result worth noting on its own.
