2

Get your plan

An AI-built plan, tuned to your goal pace, mapped week by week to race day.

3

Log your weeks

A 30-second weekly check-in keeps the prediction honest. No Strava or Garmin sync yet, so logging is manual for now.

4

The honest part

See if you're on pace for your time, every week.

Most plans hand you a schedule and hope. RacePacer compares your live prediction to your goal and gives you a straight answer: on track, slipping, or off the pace, plus exactly what to do to close the gap.

Why trust the number

Your finish-time prediction isn't AI guesswork. It's calculated from your logged paces using established race-equivalency maths, then checked against your goal every week.

I started building RacePacer after one too many training plans that told me what to run, but never whether it would actually get me to my goal time. I wanted something built around my own numbers. My times, my target, the way I train week to week. And I wanted it to adapt when real life got in the way, backing off for a niggle or a flat week, and letting me push when fitness came good.

As you log each week, the plan updates and shows you honestly where you stand against your goal, so race day holds no surprises.

It's early days, and your feedback shapes what comes next. To be clear though: RacePacer is a training tool, not a replacement for a coach, physio, or doctor. If something hurts, trust your body over the plan.

Questions

How does the prediction work?

It is not AI guesswork. We take the paces you log, apply established race-equivalency maths to estimate your finish time, and compare it to your goal every week.

Do you connect to Strava, Garmin or Apple Health?

Not yet. For now you log your weekly distance with a quick manual check-in. Device sync is on the roadmap.

Which races does it cover?

Everything from a 5K to a marathon, plus the 10Ks and halves in between.

Is it free?

Yes, free during the private beta, and no card is needed. We will be upfront well before that ever changes.

Is my data safe?

Your training data is stored in the EU, never sold, and you can export any plan or delete your account whenever you want.

Is this a coach, or medical advice?

No. RacePacer is a planning tool, not a substitute for a qualified coach, physio, or doctor. Train within your limits.
