Made by a Runner, for Runners

Built for the Miles
You Actually Run

NavRun started as a personal project. One ultramarathoner with a data analyst's brain, a software engineer's toolkit, and a stubbornly specific set of needs. It grew into something worth sharing.

The Origin Story

Why NavRun Exists

I started running ultramarathons a few years ago and quickly realized that most training tools were built for the masses, not for me. They were either too simple to be useful or so complicated they needed their own training plan.

Before I was an ultramarathoner, I was a data analyst. Before that, a software engineer. So when I looked at my Strava data and saw all the patterns hiding in plain sight -- pacing trends, recovery signals, the weeks where everything clicked vs. the ones where it didn't -- I couldn't help myself. I had the data. I had the skills. I just needed to build the thing.

"I wanted something that understood my data, adapted to my schedule, and felt like it was built by someone who actually runs. So I built NavRun."

I'm not a startup. There's no VC money, no growth team, no "user acquisition funnel." It's just me, a laptop, and a lot of long runs where I thought through what this thing should actually do. Every feature in NavRun exists because I personally needed it or a fellow runner asked for it.

Running is deeply personal. Your goals, your schedule, your terrain, your pace -- none of it fits a template. NavRun is my attempt to build a tool that actually respects that. Free to use, honest about what it is, and built to get out of your way so you can focus on running.

What We Believe

The Philosophy Behind NavRun

Runners First
Every feature exists because a runner needed it. No bloat, no gimmicks, no dark patterns. If it doesn't make your training better, it doesn't ship.
Train Smarter
AI should make training easier, not more complicated. Simple insights, real results. If you need a PhD to use a feature, we haven't done our job.
Privacy Matters
Your running data is yours. We never sell it, share it, or use it to target ads. You can disconnect and delete your data anytime, no questions asked.
Always Free at the Core
Running is expensive enough already. The tools that help you train smarter shouldn't be locked behind a paywall. NavRun's core experience is free.
