Aptos High alumna and Stanford Triathlon Club member Marissa Ferrante won the West Coast Collegiate Triathlon Conference Championships in Arroyo Grande on Saturday, according to preliminary results that will become official Tuesday at 3 p.m.

“My race went really well,” Ferrante said in a phone interview Sunday. “I made some big improvements from last year.”

The sophomore who studies anthropology completed the Olympic-distance triathlon at Cal Poly in 2 hours, 10 minutes, 55.3 seconds to finish with about a two-minute lead over the next closest competitor. Erika Erickson was second in 2:12:56.5 and Katherine Nielsen was third in 2:15:13.9.

“Some of the girls I placed ahead of yesterday placed in the top 10 of Nationals last year, so I think I’m right on target,” said Ferrante, who plans to compete in Nationals next month.

Ferrante finished the swim in 19:54.4, the bike in 1:11:56.9 and the run in 36:51.8. Coming out of the water, Ferrante was in fourth just behind the strongest swimmers, and she caught the first girl “right away” on the bike.

“I hit the run and just ran hard and ended up with a two minute lead,” Ferrante said of the final portion of the tri.

Berkeley’s Yoni Doron-Peters won the men’s race in 1:59:07.7 with just a four-second lead, Jane Smith won the female Olympic division in 2:24:55.3 and Tom Trauger won the men’s Olympic division in 2:10:50.1.

Next weekend, the Stanford Triathlon Club plans to compete at the UC Santa Barbara Sprint Triathlon. Collegiate Nationals are scheduled for April 21 in Tuscaloosa, Ala.

“Ultimately, I would love ot win nationals, but definitely my goal is to get top-five,” Ferrante said.
