I'm Proving AI Coaching Works on My First Marathon

Nico, Founder of 1st Marathon

Nico

Founder, 1st Marathon

✓ Ironman 70.3 Finisher

✓ Used to Train Actively

✓ First Marathon: May 16, 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 to fulfill that dream. I know from my previous experience (Ironman 70.3, +20km trail runs and more) that I'm prone to training too much, and it isn't always balanced.

So I built an AI coach trained on elite marathon research (Daniels, Pfitzinger, Hansons) and exercise physiology.

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

On October 5, 2025, I started training for my first marathon on May 16, 2026. Fully documented. Same AI coach you'll use. Join me and 9 other first-timers on this journey.

Common Questions About AI Marathon Coaching

I'm terrified I won't be ready for race day. How does AI help?

AI tracks your fitness progression through objective metrics — aerobic capacity, recovery rate, training load adaptation. You'll see your readiness building week by week. Trust the data showing you're getting fitter, not your fear that you haven't run the full distance yet.

How does AI prevent injury?

The system monitors multiple injury risk factors: heart rate variability (HRV) to detect overtraining, training load progression to prevent doing too much too soon, gait balance patterns from your Apple Watch data to spot asymmetries, and cross-training adherence to ensure you're building strength where runners typically get weak. By analyzing these factors together, the coaching can catch developing issues 2-3 weeks before pain appears and adjust your plan before runners knee or IT band syndrome sidelines your race.

What if I miss workouts due to life events?

The coaching system recalibrates your plan based on your actual training volume and current recovery status. You stay on track without trying to 'catch up' on missed miles (the #1 way people get injured).

What training timeline does this work for?

The coaching adapts to your schedule — up to 6 months of training. The system assesses your current fitness level and available time, then builds a progression that gets you to race day ready without rushing or overtraining.

What's included in the personalized starter assessment?

The assessment asks about your running history, other sports experience, current fitness level, and available training time. This information matches you to an appropriate starting plan. As you progress through training, the plan continuously adapts based on how your body responds to the workload.

What about strength training and mobility work?

When AI detects recovery deficits or imbalances (common with pure running), it recommends strength and mobility work. Many injuries stem from weak glutes, tight hip flexors, or poor mobility — AI helps you address these before they become problems.

How does race day pacing work?

Based on your training data — heart rate zones, long run performance, and recovery patterns — the AI calculates a realistic race pace strategy. You'll know exactly what pace to start at and how to adjust through the race to finish strong instead of hitting the wall at kilometer 30.

Do I need to wear my Apple Watch 24/7?

The more you wear it, the better the coaching becomes. We recommend wearing it for all runs (heart rate and pace data), during sleep (HRV and recovery tracking), and throughout your daily activities (steps, movement patterns, overall activity load). Tracking your full day — not just runs — helps the AI understand your complete activity picture and provide better guidance. Missing occasional data won't break the system, but consistent wearing gives you the most accurate coaching.

What level of Apple Watch do I need?

You need an Apple Watch that tracks heart rate variability (HRV). This includes Apple Watch Series 4 and newer. The AI also uses sleep data and activity tracking, which all recent Apple Watches provide.

What happens after my marathon?

This is a one-time payment for your complete training season (up to 6 months). As a founding member, if you decide to train for another marathon in the future, you'll always pay $19.90 instead of the regular $49.90 price. You lock in founding member pricing for life.

Why only 10 founding members?

With a small founding group, each member gets personalized attention and direct support throughout their training. This close collaboration helps refine the coaching system based on real feedback, ultimately helping thousands of future marathoners benefit from these improvements.
