Run from E-rank to S-rank. Kai Running turns your running training into a manhwa you live. The System chooses you as an E-rank runner and gives you a real training plan for your goal: 5K, 10K, half marathon, marathon or your own race. Every run is a Gate to clear. A REAL PLAN TO RACE DAY Tell the System your goal, your level and your race date. It builds a complete plan, week by week, and adapts it when you miss a run. EVERY RUN IS A GATE Easy runs are Recon Gates, intervals are Combat Gates, tempo runs are Chases and long runs are Raids. During the run, the System guides you by voice with your pace, your target zone and each rep. Run outdoors with GPS or on a treadmill. RACE YOUR RIVAL Ren, your rival, shows up in your hardest sessions. Hold your pace to keep him behind you. LEVEL UP WITH EVERY RUN Each Gate you clear raises your stats: Speed, Endurance, Willpower and Recovery. Stats only grow from what you really ran. WATCH KAI EVOLVE Clear Gates to rank up from E to A. Kai changes form at every rank. S-rank comes only on race day, with the Rank Exam. YOUR RUN, DRAWN AS A CHAPTER After every run, your real performance becomes a short manhwa chapter starring Kai. Read them again in your Archive, and share your chapters, your results and your Hunter License. Kai Running gives general training guidance, not medical advice. Check with a doctor before you start a new training plan. Subscription: Kai Running offers an auto-renewing subscription that unlocks the full plan and every Gate. Payment is charged to your Apple ID when you confirm the purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings. Terms of Use: https://lesnants.com/terms Privacy Policy: https://lesnants.com/privacy
