Why I built it.

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.
