Kracey

Kracey connects Claude to your own training data so you can ask about it in plain language. It is read-only and never changes anything in your accounts.

What you can ask about

• Your sessions: recent workouts with sport, duration, distance and load, and the full detail of any single session.
• Your progress: weekly volume, sport split and trends, and your training load over time.
• Your heart rate zones, calculated by five methods side by side.
• Your pace curve and best efforts.
• Your race predictions for running distances and HYROX.
• Your saved HYROX results, split by split against the same race and division, and how one of your races compares with another.
• Your heart rate, zones, training load and recovery (sleep, HRV, resting heart rate), only if you choose to share them when you connect.
• Your current plan, if you train with a Kracey coach plan.

Calculators that work before you connect any data

• Predict a HYROX finish from a running pace or a recent race, with every lap in race order.
• Plan your HYROX pacing: enter a goal time and get the run pace and station budget it needs.
• Predict your times at other distances from one race result.
• Find upcoming HYROX and running races by region and date.

How it works Sign in with your Kracey account. Your session data comes in through intervals.icu, so anything you sync there is available. Kracey only shows your own data, and no tool looks up another person. Times are given in seconds with a formatted copy alongside, and dates are your local dates.

Built by a HYROX athlete for athletes who coach themselves and want answers from their own numbers.
