The platform
Your training. Recalculated every morning.
An AI-supported training platform that plans every day from your current health data. We set your goals and season together, and the platform turns them into each day's training. Where the data ends, I'm there in person.
Works with Garmin, Coros, Wahoo, Suunto and Apple Watch.

About
From hobby to calling.
I was never a natural. I started with after-work runs, then came the first races. Every season I got a little faster, and every season I wanted to understand why.
That led to my personal trainer certification and one race season after another: road, trail, long-distance cycling. I'm married with two kids. I know how training fits around work and family because that's how I do it every day.
Now it's what I do: help more people become competitive, wherever they are in life.
I founded trainingzones.app and trainwithkalle.com, tools that turn training data into clear decisions. My athletes use them every day.

Coaching
Running and cycling. One plan.
You train for a goal, and your plan is built around it. If you do both sports, I plan them together.
Running
- 10k
- Half marathon
- Marathon
- Ultra
- Trail
From your first 10k to a marathon PB or your first ultra. For trail we plan climbing, downhill technique and fuelling from day one.
Cycling
- Road
- Gravel
- Gran fondo
- Long distance
Higher FTP, smarter pacing on climbs, 300 km without falling apart. Sportives, gran fondos or your first ultra on the bike.
Method
Platform and person. Both matter.
The platform handles the daily work: reading your data, planning sessions, adapting. I handle what data can't see.
- 01
Science as the foundation
Periodisation, lots of easy and a little hard training, zones from your own power and heart rate data. No off-the-shelf plans.
- 02
Adjusted every day
Every morning the platform reads your recovery and plans accordingly. Slept badly means a different session, not a guilty conscience.
- 03
I set the direction
Season goals, race selection, strength and technique work: we plan them together. I check your data regularly and step in when needed.
- 04
Personal when it counts
Before key races we talk on the phone, and when doubts creep in you message me. Training happens in your head too.
What you get
Plus a coach who knows you.
Personal on WhatsApp
Questions, doubts, race reports: you message me directly and I answer myself.
A call before race day
Before key races we talk it through: pacing, fuelling, mindset. And whenever motivation runs low.
Nutrition and physio
When you need it, I bring in nutrition scientists and physiotherapists from my network, so you stay healthy and perform on race day.
Athletes
What athletes say.
Sven got me to a sub-3 marathon in Cologne this year. All I needed was his training platform and an extra push the day before.
AlexanderCologne Marathon, sub 3 hours I smashed Vätternrundan in under 9 hours, which was my dream goal.
AnnikaVätternrundan, 315 km Sven knows his science and always makes sure that my training plan fits my life.
ClemensRunner Unbelievable. I didn't know how effective training can be. And all while being a dad.

FAQ
Good to know.
- Anyone who wants to get better: from a first 10k to an ultra trail, from a first gran fondo to 300 km in one go. Age and current level don't matter. We start where you are.
- With a free intro call. We talk about your goals, your week and your training data so far. Then you get access to the platform and your first week of training.
- Garmin, Coros, Wahoo, Suunto and Apple Watch, connected through intervals.icu. Structured workouts are sent automatically to Garmin devices. No watch? That works too: you log how the session went.
- The platform uses an AI language model to turn your data, your plan and your messages into the right session each day, with a reason. The training logic behind it, periodisation, zones and load management, follows fixed sports-science rules. And I keep an eye on everything.
- €99 a month or €999 a year. Everything is included: plan, platform, WhatsApp, calls before races and access to my network. Training together in person is €150 per hour extra. As a small business I don't charge VAT.
- Yes. Coaching runs online and works anywhere, in English or German. In person, I train with athletes in south Berlin: Kleinmachnow, Stahnsdorf, Teltow, Zehlendorf, Dahlem, Lichterfelde, Wannsee and nearby.
- Yes. Both sports go into one plan, so the training load complements rather than stacks up.
- Periodisation, an intensity mix with lots of easy and a little hard training, zones from your own data, and daily planning that accounts for sleep and recovery. I update the method when new studies come out, not when trends do.
- I'm an NFPT Certified Personal Trainer and an NFHS Cross Training Coach. On top of that come years of my own racing, from Vätternrundan to a 100-mile ultra at Mt Fuji.
