Welcome to TC-triathlon School

Online school for athletes and coaches

Hello everyone. My name is Tanakorn Cheeptumrong.

You can call me TC. My first triathlon was back in 1997 when I was only 16. I am an Ironman Finisher at Ironman Langkawi 2014 and 16 times Ironman 70.3 or middle distance finisher. Mostly, I live, work and train in Bangkok, Thailand.

Currently, I am working full-time as a triathlon coach and sports lab specialist at STAGE Find The Real U. You may get to know me more through my blog at www.tc-triathon.com.(link is external)

 It is all about inspiration, knowledge and race review all over Asia and Australia.
