Race prep for runners who already follow a plan
Your plan tells you what to run.
Pacexis tells you how it's going, and how to race it.
Pacexis reads every run against your plan and tells you in plain words what happened and what to change. In race week it turns your course into a pace plan you can actually follow.
What Pacexis tells you.
Specific, from your own data. No generic motivation, no scores you can't explain.
“Third easy run this week above your easy pace. Slow down on Friday, Sunday's long run needs the legs.”
“Reps 4 and 5 faded by 12 seconds. Start the first rep 5 seconds slower next time.”
“Km 14 to 17 is the hardest part of the course. Hold 5:10 there and you still finish under 1:45.”
While you train
- Every run read against your plan: pace, heart rate, splits, and what to change
- Today's session and the shoe to wear for it, so your rotation wears evenly
- How it felt and any pain, logged in two taps and linked to your shoes and sessions
- Weekly and monthly reports on where your running is heading
Race week
- Upload the course GPX and get a target pace for every kilometre, adjusted for the hills
- Gel timing along the course
- A written briefing: where it gets hard, where to hold back, where to push
- Share it with your club or your pacer with a link

Questions runners ask.
Does Pacexis write my training plan?
No. Pacexis works on top of the plan you already follow, from Runna, TrainingPeaks, a coach or your own. It reads every run against that plan and helps you race it.
Where do my runs come from?
From your phone. Pacexis reads your runs from Apple Health on iPhone or Health Connect on Android, read-only, so whatever watch or app records them there shows up. Your plan comes in separately, by iCal feed.
Are race briefings free?
No. Race briefings are part of Pro. New subscribers get a 14-day free trial, and the trial includes them.
Who writes the feedback?
Anthropic's Claude, from your own data, and only if you allow it.
Where is my data stored?
On servers in the European Union. Encrypted in transit. Pacexis never sells your data and never trains foundation models on it. The full policy is on the privacy page.
Can I cancel anytime?
Yes. Pro is billed annually or monthly, with a 14-day free trial. Cancel from the app and you keep access through the end of the period. Your data stays yours either way.
