The hardest part of ultra running shouldn’t be the planning.
Less guessing, more solutions that work.
You’ve got the discipline. You’ve got the hours. What you lack is certainty — and variety in your training.
You plan your weeks around training and still wonder if you’re doing the right things. The data from your watch doesn’t tell you what to change. The templates don’t know what happened last week. And if you’ve never run the course, you’re planning race day on assumptions — the terrain, the gaps between aid stations, how much food and water to pack. The closer the start line gets, the less confident you feel.
You’re not undertrained. You’re unsupported.
A training platform that removes the guesswork from ultra preparation.
Laakso is a new kind of ultra running platform that combines scientific research with the real-world experience of ultra runners. Laakso recalculates your plan every week based on what’s actually happening — your watch data and how you feel. Miss a week, it adapts. Push too hard, it pulls back. Training, nutrition, course analysis, race day planning — one platform for your entire ultra season. Laakso isn’t designed to just tell you what to do, but to help you understand why.
Adaptive training
Laakso reads your aerobic efficiency and subjective readiness week over week, adjusts volume and intensity, with built-in guardrails for vertical load and taper.
Gut training
Laakso's progressive protocol helps you find your personal carbohydrate absorption rate and build confidence in your race-day nutrition, session by session.
Watch integration
Your data flows in automatically. Available now: Garmin, Suunto, Polar. Coming soon: Oura, Coros.
Course-specific training matched to your actual race profile
Knowledge from runners who’ve raced the course before you
Race day scenarios — course and aid station breakdown, pacing strategies, nutrition and gear planning
Help us build this.
Laakso is still a work in progress and we want ultra runners involved from the start. Try features, give feedback, and shape where the app goes next — early access is completely free.
