The story behind TTM

There was no tool that told me the truth about my readiness.

"I trained harder than I ever had. But I arrived at altitude unprepared - not from lack of effort, but from lack of the right information."

Jakob - founder & mountain athlete

My name is Jakob and I'm a mountain athlete. Like many people who pursue alpine climbing and high-altitude mountaineering, I've spent years building strength, endurance, and technical skill. I've logged thousands of vertical meters. I've trained periodically, tracked my Chronic Training Load (CTL), optimized my Acute Training Load (ATL). I did everything right - or so I thought.

But when I arrived at altitude for my objective, I wasn't ready. Not because I hadn't trained hard enough. I'd trained harder than ever before. The problem was different: I didn't actually know if I was cardiovascularly prepared for the specific altitude and duration of my climb. I had data scattered across different platforms - my Garmin tracked metrics, various apps logged my sessions, a spreadsheet held my plan. None of them actually understood whether I had the VO₂max, the aerobic base, the Acute Training Load (ATL) resilience, or the Training Stress Balance (TSB) profile to succeed at the altitude I was targeting.

I looked at every tool available to mountain athletes. Endurance training platforms are powerful - but they're built for cyclists and triathletes working with coaches. They don't understand altitude physiology or mountain-specific demands. Mountain-specific coaching platforms have excellent methodology rooted in solid exercise science - but the training is rigid, template-based, with no adaptive engine. General fitness and activity trackers don't even attempt to model readiness. They're logbooks, not intelligence systems.

The insight came when I realized something that changed everything: The science already exists. The Banister fitness-fatigue model has existed since 1975. We understand VO₂max decline at altitude. We know how Chronic Training Load (CTL), Acute Training Load (ATL), and Training Stress Balance (TSB) predict athletic performance. We can model the Summit Readiness Score (SRS) - the probability of success at your specific objective altitude and duration. What was missing wasn't research. It was a platform built for mountain athletes that integrated real Strava data, applied altitude-specific exercise science, and made it conversational and adaptive instead of rigid.

So I built the tool I wished had existed: Train to Mountain. Not another training app. A unified training intelligence system that understands what it actually takes to arrive at altitude ready. Shaped by the physiology of altitude, and designed from the ground up for mountain athletes like you and me.

One platform. Every mountain discipline.

Today, Train to Mountain focuses on what we know best: alpine climbing and high-altitude mountaineering. But the vision is much larger.

Today
Alpine climbing, mountaineering
Building Now
Trail running & ultramarathon, ski touring & ski mountaineering, high-altitude trekking
The Long Vision
Every aerobic mountain sport where cardiovascular readiness determines whether you reach your objective

The model scales because the physiology is the same. Across alpine climbing, trail running, ski touring, and high-altitude trekking, the factors that determine success are remarkably consistent: VO₂max at altitude, the Banister fitness-fatigue relationship, periodized progression, and the ability to sustain aerobic effort in thin air. One intelligence system can serve them all.
