"The dashboard insights completely changed how I track my progress. Seeing my cumulative distances and PRs visualized made me realize I perform better when logging more training miles and not overdoing it with carbs pre-race."

"The training notes feature is a game-changer. I can track which shoes I wore, my weekly mileage, and how I felt after each race. Really helped me identify the perfect race day setup."
Marcus Chen
PB: 2:58:33 • Chicago Marathon • 2024
"The auto-generated race checklists saved my Tokyo Marathon. I customized it with my gear preferences and never forgot a single thing, even with a couple flight delays. Even remembered my lucky socks!"
