Great coaching needs context

Turn your training
data into coaching context

Connect your training data to Claude or ChatGPT so AI can answer questions like a coach who already knows your runs, workouts, and trends.

Without your training history, AI can only guess. Connect Strava once and get answers grounded in what you actually did.

What Changes

The connection is the product

Your training context lives across Strava, COROS, and your AI setup. Chirona turns those separate sources into one coaching layer.

Afternoon
Am I ready for a half marathon in 6 weeks? Compare my last 4 weeks to the month before, check my current training paces, and use my COROS fitness profile if it helps.

Loaded tools Chirona
Claude is calling Chirona tools across Strava and COROS for volume, load, pace zones, race readiness, and fitness profile.

4-week avg 51 km Threshold pace 4:08 /km HM prediction 1:31-1:33
You have enough recent volume and threshold support for a strong half. The next move is sharpening, not simply adding mileage.
Readiness
On track for roughly 1:31-1:33 if you keep one threshold workout and one quality long run each week.
Why
Training load is stable, your recent block is stronger than the prior month, and COROS threshold pace lines up with your training zones.
Next Step
Hold volume near 50-55 km, add one half-marathon-pace segment to the long run, and taper race week instead of chasing extra distance.
