    Tim is very knowledgeable . I did a sweat sodium test and it was a great experience , Tim took time to go over lots off details and I m looking forward to put this information to use in my next event

    I’m training for a 100-mile trail race and was looking for some expert help with training and nutrition. I found Endurance PTC online, saw the great reviews, and booked a performance assessment—so glad I did! The session was super thorough, and both Caroline and Tim were incredibly patient and genuinely interested in helping me reach my goals. They broke everything down in a really clear, practical way and took the time to answer all my questions. I left feeling way more informed and confident about what’s ahead. Highly recommend!

    Tim is an absolute gold mine of amazing training information and physiological information. After multiple testing sessions with him I’ve managed to completely revamp my training and better understand my body.
