The philosophy that turns you into a finisher

Most training plans treat strength and mobility as extras. We built them in from day one — because balanced training prevents injuries and builds confident runners.

Real Journey, Real Training

I'm Proving This Works on My First Marathon

Nico, Founder of 1st Marathon

Nico

Founder, 1st Marathon

Ironman 70.3 FinisherFirst Marathon: May 2026

I used to train - a lot. Then life happened, I started a family and the training mostly stopped. But my dream of finishing a marathon stayed alive.

Now it's time. But I know myself. I tend to overtrain and do workouts that are fun rather than what actually supports marathon performance. I needed something to keep me balanced and accountable.

So I built an AI coach that actually adapts to real life. One that handles the planning so I can focus on showing up.

Now I'm proving it works by using it myself.

Questions & Answers

If You're Wondering…

Do I really need a coach? Can't I just follow a plan?

A static plan can't adapt when life happens. When you miss a workout, get sick, or have a busy week, a fixed plan just keeps marching forward—leaving you to guess how to catch up (which often leads to overtraining or injury). An adaptive coach recalibrates in real-time, keeping you on track without the guesswork.

What happens if I get sick or injured during training?

Just report it in the app. If you're sick, your plan immediately adjusts—reducing intensity and volume while you recover, then gradually building back up. If you feel pain or a tweak, the system modifies workouts to protect that area while keeping you moving. No guessing, no panic.

Do I really need strength and mobility work?

50% of first-time marathoners get injured before race day. Most running injuries don't come from running itself—they come from weak glutes, tight hip flexors, poor mobility, and muscular imbalances. By integrating strength and mobility from day one, you build the resilience that keeps you running.

Is the app available on Android?

Not yet—we're iOS only for now. We're focused on making the iOS experience great first before considering other platforms.

Do I need a smartwatch or heart rate monitor?

No. The training plans are built around perceived effort and your feedback, so no extra gear is required to get started.

How far out from my marathon should I start?

We require a minimum of 14 weeks for experienced runners, and longer for beginners. We won't create a plan that's unrealistic or sets you up for injury. If you don't have a race yet, you can start with our base building plan and enroll in a race when you're ready.

What if I'm a complete beginner who's never run before?

We support runners planning their first marathon. If you don't have a race date yet, you can start with our base building plan to develop your fitness, then enroll in a race when you're ready. We create training seasons up to 52 weeks—plenty of time to take a complete beginner to the finish line.

Is the founder a beginner too?

Yes! I'm training for my first marathon right now using the same AI coach you'll use. I've done endurance events before (Ironman 70.3, trail runs), but never a full marathon. Building this while training for it means I'm constantly finding and fixing what doesn't work in real life.
