Ask anything about your training and get evidence-based answers grounded in your specific context, not a generic guess. For coaches, KULG saves time on admin and data review — more room for the conversations, race-day calls, and individual attention each athlete actually needs. WHAT YOU GET - Ask your AI training assistant anything about your training - One clear, unified view of your training and recovery - Set goals and track weekly and monthly progress - Automatic sync with Garmin, Strava, Oura, and more - Collaborate directly with your coach, or train solo - Built specifically for running — not adapted from cycling or triathlon tools KULG works on top of your existing trackers. Not a replacement for them.
