Saga vs Coach Leo

The application is a comprehensive tool designed to assist athletes and coaches in the meticulous planning, execution, and analysis of blood lactate testing protocols specifically for running and cycling activities. Its core objective is to streamline the process of determining an athlete's lactate inflection point (LIP) or lactate threshold, a critical indicator of endurance performance and metabolic efficiency.

Why do you run? For the silence at 6 AM? To feel something other than your screen? Because the mountains don't care about your job title? Whatever your reason: Leo coaches around it. Leo is an AI running coach that syncs your runs, remembers every conversation, and gets sharper every week. This is coaching, not a dashboard: no charts to decode, no metrics to interpret. You just talk to Leo. A REAL PLAN, BUILT ON YOUR RUNS Tell Leo your goal — 5K, 10K, half, marathon or ultra trail — and he builds a periodized plan anchored to your current fitness, read straight from your real training history (paces, weekly volume, longest run). Real structured sessions: intervals, tempo, long runs, hills, recovery — not a wall of identical jogs. And he's honest about your goal: he'll tell you if it's realistic and what it would take, without ever capping your ambition. HE KNOWS YOUR BODY Most apps track numbers. Leo asks how your legs felt, how you slept, whether that knee is still tight... and turns sensations into decisions you can trust. He watches your training load week by week and speaks up before a breakdown does; not with jargon, but with "take tomorrow off." HE READS THE SCIENCE Built on 150+ peer-reviewed papers: periodization, biomechanics, nutrition, physiology, altitude. Leo doesn't recite research; he applies it to you. He remembers that your left calf acts up after heavy weeks, that you race better with a 3-day taper. MORE THAN A COACH: A RUNNING WORLD From your real training, Leo reveals your running character across 9 dimensions: endurance, speed, mountain sense, consistency and more. Not a quiz: who you actually are as a runner. Join a pack that shares your strengths, chase solo quests and pack challenges, and follow your crew's expedition across the map. Play, don't just train. COACHES WHERE YOU ALREADY ARE Talk to Leo in the app, on Telegram, or right inside ChatGPT, Claude and Mistral (any MCP-compatible assistant).
