Problem
In 2026, marathon events are held weekly in Korea, and the running population has surged, but over 70% of amateur runners in their 30s-50s train without professional coaching, relying only on YouTube and community information, and suffer knee, ankle, and Achilles tendon injuries. A single injury costs an average of 500,000-1,500,000 KRW (approx. $375-$1,125) for orthopedic treatment and rehabilitation, with a recovery period of 4-12 weeks, making race entry fees and equipment costs sunk costs.
Solution
A mobile web service that automatically calculates overtraining risk when you input weekly training volume (distance, pace, elevation), and pushes daily personalized stretching and strengthening routines based on body type, running experience, and past injury history. It combines a race D-day reverse periodization plan with an injury symptom self-check questionnaire, and when risk signals are detected, it provides one-stop connection to nearby sports medicine clinics for appointments.
