I am a seasoned athlete in the sport for more than 12 years and have done everything from 0 structure to self-coaching to 1:1 coaching. If you know your zones and can stay accountable without a 1:1 coach, I HIGHLY recommend this plan! It was a great balance of everything you need to have a successful race. I especially enjoyed the added durability from the core work and recovery sessions, which paid dividends in injury prevention. Also, the plan includes detailed explanations and articles that help frame how to approach the workouts and the process. Never once did I feel burned out or overtrained. On race day, I was prepared and excited, which translated to a 35-minute PR and a Kona spot. It's quite possible I will repeat the same plan for Kona!
