Why Train With TMR Plans for TrainingPeaks?
“I’ve been following Doug’s 100-mile intermediate mountain ultra plan for the past year. It has helped me complete some long mountain races and even win my age group in a road half marathon during training.
I also loved the strength training regimen. The plan is consistent and the repeated workouts help me see weakness or improvement. I really recommend it!”
— Richard, multiple 100-mile finisher
“The trail marathon training plan was so easy to follow and helped me complete my goal race. It’s also great that you have the plan for life, so you can re-apply it to your TrainingPeaks account and start again when you sign up for your next goal.”
— Anna, trail marathon runner
“I used Doug’s plan to prepare for Celtman X-Tri and loved it. It got me round the course, plus it has some really good tips for how to manage the race day and the crewing (which can be really tough in these extreme triathlons).
Doug was also really responsive when I had a few questions, which really helped.”
— James, Celtman X-Tri finisher
