our board:

Calvin Men


Calvin has been a part of SCTA since 2016 and have seen the community/club really grow from there. It's something that he has grown to love and cherish, which is why he joined the board and became a steward of this community. As a board member, Calvin wants to continue building the momentum we've gained in the past year and move the organization into a better place next year and for years to come.

Cathy Yoon


Cathy Yoon first heard about SCTA during a Nu2Tri information meeting in 2012.  On a dare from a friend, she signed up for Nu2Tri Class of 2012 not knowing how to bike.  During the first bike clinic, she got on a member's mountain bike and biked around the parking lot with SCTA members supporting her every step of the way.

She has since completed four Ironman 70.3s and finished IRONMAN Arizona 2015!  When not training for a triathlon, she is running RAGNAR relays.

Jon Erskine

Workout Coordinator

Jon raced in the Ironman World Championships in Kona. The Big Island! He has also raced the IRONMAN® 70.3 World Championships in Mooloolaba, Queensland, Australia!

Jon came to triathlon with an extensive background in bike racing and running. You'll find Jon crushing his enemies out on the race course.

David Rabow


David came to triathlon as he turned 50 and completed Nu2tri in 2015.  He is a middle of the pack racer with poor swimming, mediocre riding and (as shown above) sometimes walking after a hip replacement.  When not riding his bike he is often at the dog park with his large beast Bixby.  David joined the Board in 2023.  On race day he is often cheering a special someone to a podium finish.

Sarah Kletzer


Sarah has competed in the Ironman 70.3 World Championships in St. George, Utah (2021 and 2022). She regularly races in the 70.3 distance and below. She came to triathlon from a competitive swimming background and can still be found coming out of the water at the pointy end of the race.

Steve Doinidis

Clothing Coordinator

Steve raced in the Ironman 70.3 World Championships in St. George, Utah in 2021 and 2022. He can often be found at the front of the race, sometimes in just a Speedo. He has raced multiple Ironman races and just might do some more in the future (depending on what his wife and daughter have to say about it).

Perian Fein

Social Events

Perian started doing triathlons in 2015 with her daughter Amanda. As her interest in competing grew, she joined SCTA with the hope of expanding her training community. What she found was a group that is inclusive, supportive, competitive, and incredibly inspiring. The membership ranges from the best triathletes in Santa Cruz County to those new to the sport, so she was able to connect with athletes who matched and challenged her pace and race level. Perian appreciates how they celebrate each other’s accomplishments, marvels at the variety of event they compete in, and learns from their race reflections. 

Geoff Drake


Endurance sports have pretty much been Geoff's life, personally and professionally. He was the editor of VeloNews and Bicycling magazines, which meant he got to travel all over the world attending races like the Tour de France, as a journalist. Geoff a Cat 2 road racer and Cat 1 mountain bike racer. He has been a professional bicycle mechanic, a USCF certified coach, and has taught classes in bicycle maintenance and riding in traffic. Geoff has done a couple of full Ironmans (badly), and did his first tri in Olympia, Washington, in 1981. These days Geoff enjoys Olympic-distance races in the codger category.  

Jacob Castanon


While I am still new to the sport, I feel I have accomplished much in a short period going from the Nu2Tri program in 2021 to completing my first 70.3 at Ironman Santa Cruz in 2022. 

I love the sport. For myself, it has brought me much health and happiness. I am passionate about the club and the social aspects it provides, which can often be over looked by athletes in individual sports. 

The friendships forged in our training blocks are critical to enjoyment and longevity in the sport. 

BJ Snider 



I was looking for an inexpensive road bike because I thought I needed one to do triathlon and saw a small poster promoting the Santa Cruz Triathlon Association (SCTA). I found a fantastically inclusive group of people who were passionate about not only triathlon, but fitness and health in general.

With the help and encouragement of my SCTA friends and teammates, I've gone on to complete many Olympic and Sprint distance triathlons, Ragnar Road and Ragnar Trail races, 1/2 marathon trail races, 50K Ultra races, 1/2 IronMan triathlon, and Grand Canyon Rim-2-Rim-2-Rim a couple of times.

Now I spend my time trying to give back to this community that has given so much to me.
