F20-24: Tiffany Chen dominates a fog-chilled San Francisco 5K

• Tiffany Chen wins in 22:30 (7:15/mi) — more than two minutes clear of 2nd place in a 64-finisher F20-24 field.
• Erica Robinson (24:38) and Elyssa Dimaano (25:19) round out the podium, separated by 41 seconds.
• Bianca Pak (26:25) and Urvi Joshi (27:24) claimed 4th and 5th, with a tight cluster of five runners — Emma Ryan through Christina Lin — finishing between 28:02 and 28:17.
• Rohini Singh crossed 11th in 29:05, the youngest finisher in the top 20 at just 20 years old.

Under a grey San Francisco sky — 53°F, damp at 95% humidity, and a steady bay breeze — Tiffany Chen made the F20-24 race her own from the outset. The 24-year-old local finished in 22:30 at a 7:15/mi clip, a margin of 2:08 over second place that left no doubt about who owned this race. In a 5K, that kind of gap isn't a close call — it's a statement.

Erica Robinson (Troy, MI) made the trip west worthwhile, claiming 2nd in 24:38, while Dimaano — another San Francisco local — held off the rest of the field to take 3rd in 25:19. The 41-second gap between them was real but not insurmountable; the real story was how cleanly they separated from the pack behind them. Bianca Pak (4th, 26:25) and Urvi Joshi (5th, 27:24) ran solid races at 8:30 and 8:49 per mile respectively, but the podium was already sealed.

The race's most compelling subplot came just behind them: five runners — Emma Ryan (6th, 28:02), Tung Kong (7th, 28:07), Sabrina Serafica (8th, 28:16), Christina Lin (9th, 28:17), and Maria Pedroza Maciel (10th, 28:57) — packed into a 55-second window from 6th through 10th. Five seconds separated 6th from 7th, and a single second split 8th from 9th. Further back, Rohini Singh (11th, 29:05) led a tight cluster of four runners — Singh through Brittney Kelly — all finishing between 29:05 and 29:25 and all running at 9:22–9:28/mi.
