"TrainAsONE's algorithm felt like a mystery — I never understood why my plan changed. PeakRunner shows me my CTL, ATL, and TSB so I actually learn about my training. The AI coach explains everything in plain English."
"I switched from TrainAsONE because the interface felt stuck in 2015. PeakRunner is modern, fast, and the injury prevention alerts have kept me healthy through my entire marathon block."
