Coach Jon

john-closeupJon Muncie is a graduate student member of the Cal Triathlon team. He has been racing triathlons for four years, finishing three Ironman 70.3 events and competing in the 2015 USAT Collegiate National Championships. He plans to return to the USAT Collegiate National Championships in 2016 and is working to progress to a podium-finishing age-grouper in the next few years. Before entering the sport of triathlon, Jon was a mid-distance track runner and soccer player. One of his favorite parts of triathlon is the variety and balance brought about by training for swimming, biking, and running.

Jon began coaching as a volunteer with Otter Tri during the summer of 2015 and is thrilled to return as a full-time coach this fall. He loves introducing the sport to kids at a young age and helping them achieve their goals. The reaction he gets when he tells people he works with a youth triathlon team is, “Wow! I can’t imagine training for a triathlon and there are kids doing it?!” Jon feels the same amazement and pride every time he coaches with Otter Tri.

If you have any questions, feel free to contact Jon.


Coach Varun

varunVarun Pemmaraju recently graduated from UC Berkeley and then briefly “retired” (much like Jordan) from triathlon at the youthful age of 22. In his “long-ago” past life, he was a member of the Cal Triathlon team, where he served as President and Captain for 2 years. During his magnanimous rule, Cal Tri won a women’s national title, 2 relay national titles, and finished everywhere from 2nd to 3rd, though Varun admits that he contributed essentially nothing to that success. In spite of that, he was inducted into the Cal Triathlon Hall of Fame in 2014.

Before beginning triathlon as a college freshman, Varun did not know how to swim. Rather he was a landlubber who played soccer for a State Cup winning club and ran XC and Track for Lynbrook High School. He to this day struggles to drag himself to the pool when there’s a game of pickup soccer (or basketball, or football, or even Laser Tag or putt-putt golf) to be had. He has volunteered coached for AYSO VIP, a program that coaches soccer for mentally and physically challenged kids. He also established a program with the Cal team in partnership with Challenge Athletes Foundation and subsequently acted as a guide at practices for the student-athlete who eventually became the first blind collegiate paratriathlete at Nationals.

Currently, Varun is a software engineer in San Francisco at Strava (so get your kids their first smartphone!) and has newfound goals to continue pursuing triathlon at a high level in the years to come, as well as share the multitude of benefits of the multisport lifestyle with the Otter Tri kids.

If you have any questions feel free to contact Varun.
