Made by a Runner, for Runners
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
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 It Does
NavRun connects to your Strava account, reads your training history, and turns it into plans, predictions, and feedback that fit the runner you actually are. Here's what's inside.
Weekly plans built around your recent training, your race, and the week you actually have.
5K to ultramarathon finish time estimates based on your actual training data.
Connect once, and your runs flow in automatically. No manual logging.
A read on how the run went, and what it means for the next one.
7-day forecasts for your planned runs so you can dress right and plan ahead.
Training trends, weekly mileage and pace charts, from your own runs.
Two ways to run
Generative AI affects this community, and plenty of runners want less of it in their lives. That is fair, and it is why this is a choice.
Knowing how to train for an ultra sits with veterans and with coaches most of us cannot reach. It is in here so nobody gets gatekept out of this sport.
Your week written for you, each run read back, weekly reports, race strategy.
Your week built from your own runs by rules. Same caps, same rest days.
Runs, heart rate, race goals and Apple Health workouts go to Anthropic or OpenAI. Neither trains on them. You set it either way, and you can change your mind any time. One thing stays on whichever you pick: voice clips in a live session get checked before your crew hears them.
What We Believe
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.
NavRun is at its best for the runner coming back, struggling, or dead last. It forgives the gap, and it never makes you feel behind.
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.
Running is expensive enough already. The craft of training for an ultra, the part you need to get out there and belong, is free in NavRun and it stays free.
Connect your Strava and NavRun starts from wherever you are today, no proving yourself first. It runs the miles with you.
