You

I have my first marathon in 3 weeks and I can't stop overthinking everything that could go wrong.

Kona

That pre-race anxiety is completely normal, especially for a first marathon. Those "what if" thoughts are actually your brain trying to prepare you. Let's work with that energy instead of fighting it. What feels like the biggest worry right now?

You

I'm worried I'll hit the wall at mile 20 and not be able to finish.

Kona

I can see from your Garmin data that you've completed three 18+ mile runs in the last month with solid pacing. Your body has done the work. Let's build a mental strategy for mile 20 so your mind is just as prepared...

How It Works

Get Started in Minutes

NAFAS adapts to you from day one. No complicated setup, no generic advice.

Tell Us About You

Complete a quick onboarding: your sport, experience level, race goals, stress patterns, and how you prefer to receive support. Kona uses this to personalize every interaction.

Connect Your Garmin (Optional)

Link your Garmin device so Kona can see your training load, recovery status, and workout history. This gives conversations real-world context about how your body is actually doing.

Chat, Check In, Grow

Talk to Kona when you need support, do regular check-ins to track your mental state, and watch your psychological resilience grow alongside your physical training.

Powered by Your Data

NAFAS integrates with Garmin Connect to bring real physiological context into every conversation. When Kona knows your training load spiked or your sleep quality dropped, the support becomes far more relevant.

Your body and mind are connected. NAFAS makes sure your mental performance tool understands both.
