Less guesswork. More legendary training. Lactate Training is an AI coach for runners, cyclists and triathletes who train around work, family and a changing week. Ask about your training. Add how it felt. Learn what to try next. No blood lactate test needed. Start with the watch data you already have from Garmin or Strava. TRAINING HARD BUT NOT SURE WHAT'S WORKING? • What should I do today? Tell your coach how you feel and get today's session, based on your plan, your sleep and your recent training. • Why did that session feel hard? Your coach reads the recording, compares a similar session and asks what else was going on. • Am I improving? See pace and heart rate trends side by side, explained in plain English. • How do I fit training around life? Move a session or add a work trip and your week adjusts. Nothing changes until you say yes.
