Coaches & Exec

The Exec

The club exec, a mix of student and community members, provides overall leadership to the club and handles a lot of the behind the scene tasks, including budget planning, organizing workouts, facilitating events such as our Swim-Row-Go, social events and club races, and leading a variety of workouts among other tasks!

Sayaka (otherwise known as Sai) Social Coordinator


Say first got in to triathlons on a whim – “I swim and I run, so all I have to do is add a bike ride, right?”. She has never looked back and was fortunate enough to find great friends and training partners through the UofT Triathlon Club. Her motto is Work Hard, Play Hard – you will find her grinding it out at most practices but always up for some non-triathlon related fun!

Ask her about: your aches and injuries (a registered physiotherapist by day), core and general strengthening, shorter course racing like sprints and olympic-distance



Sierra Valeriano – Administrative Assistant

Sierra began triathlon in 2013 as a distance runner who had no idea how to swim and had never sat on a road bike before. Eight months later, she completed her first half Ironman, something she could not have even attempted without some amazing tri club friends to support her. She is now in her first year of law school at University of Toronto and will be attempting her first full Ironman. Tri clubs like U of T Triathlon are awesome for finding both life-long friends and dedicated athletes to push you to be your best. If you are thinking about joining triathlon and U of T Triathlon, no matter what your level of experience, I encourage you to come try it out. Hope to see you at practice!

James San Pedro- Swim Coach

James has coached the U of T Triathlon Club Swims for nearly a decade, and brings seven years’ experience as a Junior-National Level competitive swimmer for the Arden Hills Aquatic Club in the US. Initially taking on the coaching role to help him complete his Bachelor’s Degree at U of T (Anthropology, Human Biology, and Physiology), he’s stuck around in hopes that being surrounded by positively inspiring, goal-oriented, and passionate people would encourage him to also find his own. By training with James, you will be empowered with tools to quantify your efforts, gain a distinct appreciation for proprioception, and ultimately, the ability to safely complete your swim leg with efficiency and grace. If you’re still reading this far, know that James also finds it strange to write in the third person, but sees it as a necessary evil in order to continue practicing his craft. He has most recently founded a youth multi-sport club in order to put his theories of movement, cultural inception, and education to practice.
