This program was awesome. After many seasons riddled with injury I learned how to run based on my heart rate and to be ok with running slower while training.
I had to opt out of a 70.3 due to a back strain and started this plan as redemption. I stayed healthy throughout the plan and even came in 10 min under my goal time. The mixture of swim, bike, run also took wear and tear off of my legs.
Thank you for helping me complete my first marathon in 12 years.
