WHY RUNNERD

Why I built RunNerd

I'm not a runner by background. I'm a lifter who became a runner — and the app I needed didn't exist. So I built it.

A few minutes with the founder.

THE APP

Built around four tabs you'll actually use.

Today tab in RunNerd
Today's run, today's context
Week tab in RunNerd
The plan, in motion
Coach Chat in RunNerd
Coaching that knows your runs

"I started running and discovered I needed a coach who knew my data. So I built one. RunNerd is what I use every Tue/Thu/Sat."
