Claude de Pace is a personal running coach that works entirely through Telegram, helping runners build consistency with training plans, workout reports, reminders, and adjustments based on their progress. It creates a weekly schedule tailored to each person’s goals, experience, and limitations, then adapts the plan when life intervenes, including missed workouts, fatigue, or illness. Runners can submit brief post-run reports, review or correct them, and ask to move a specific workout to another day.

The service supports beginners with a nine-week walk-run program designed to build up to 30 minutes of continuous running, as well as experienced runners preparing for multiple races or personal-distance goals. As training history develops, Claude estimates fitness, heart-rate and pace zones, lactate threshold, VO₂ max, and race times using recent reports and the Daniels VDOT model. These are training estimates, not laboratory results or medical advice.

Claude also remembers user-provided details, such as habits and injury history, and offers adjustable reminders in Russian or English.
