F50-54 Half Marathon: Johnston Dominates with a 10-Minute Gap

By MyRace AINovember 2, 2025Official site ↗
  • Seventhia Johnston won the F50-54 group in 1:40:48 (7:41/mi), finishing more than 10 minutes ahead of runner-up Stephanie Gendron.
  • Johnston climbed from 73rd among women at the 1-mile mark all the way to 20th among women at the finish — one of the day's most dramatic rises through the women's field.
  • Gendron and Malone traded places through the middle miles, with only 15 seconds separating 4th (Michele Rossi, 2:04:21) and 5th (Candie Malone, 2:04:36) at the line.
  • The top-10 in F50-54 spanned just over 27 minutes, with a tight cluster of six runners finishing between 2:04 and 2:08.

Seventhia Johnston, 54, out of Chowchilla, turned in a performance that simply wasn't close. Her 1:40:48 — a 7:41-per-mile clip on a warm November morning in Fresno — was in a different conversation from the rest of the F50-54 field. She didn't come out of the gate leading the women's race; she was 73rd among women through the first mile. But she reeled in competitor after competitor, landing 21st among women at 10K before settling 20th at the finish. She also posted the 23rd-fastest women's split from 10K to the finish line — a strong closing stretch that confirmed this wasn't a front-loaded effort.

Stephanie Gendron (1:50:51, 8:27/mi) was a clear second but had a race of her own to navigate. She moved well through the opening miles — posting the 39th-fastest women's split from mile 1 to 10K — but faded from 29th among women at 10K to 50th by the finish, suggesting the back half took its toll. Sandrine Logan rounded out the podium in 2:01:00, moving steadily from 256th among women early on to 120th at the finish.

The real drama in F50-54 played out between places 4 and 6. Rossi (2:04:21) and Malone (2:04:36) were separated by just 15 seconds, with Chee Vang (2:05:01) just 25 seconds further back. Malone had actually been ahead of Rossi through 10K — sitting 121st among women to Rossi's 176th — but Rossi's stronger closing split flipped the order at the tape. Three women, three different trajectories, all arriving within 40 seconds of each other.
