How it works
Three steps. No map-reading required.
/ 01
Plan the route
Draw or import a route, and loopline plots the distance, vert, and grade before you step outside.
/ 02
Run the line
Your watch tracks the splits against the route — pace, heart, and where you pushed the descents.
/ 03
Read it back
Splits, elevation, and trends land in your log, so every run teaches you something for the next.
02
Everything but the blisters
Hear the trail, lose the friction.
Route builder
Draw a line and get distance, vert, and grade in one pass.
Elevation profiles
Every route comes with a profile you can actually read.
Live splits
Your watch talks to the route, and the splits come back clean.
Race calendar
Find the next start line, filter by distance and vert.
Crews & segments
Run with a group, or chase a KOM on your own loop.
Works offline
Routes and profiles cached, so a dead zone never ends the run.

04
Read the elevation
The vert is the route.
Flat miles lie to you. The elevation profile tells the truth — where the climb starts, how long it holds, and what you'll have left for the descent. Loopline plots it before you ever lace up.

From the desk of Dana Osei
I started loopline because I was tired of getting lost.
Every runner I know has a drawer of dead GPS files — routes that looked great on a map and turned out to be a cliff, or a river, or someone's driveway. The map was never the problem. The line was.
So we built the thing I wanted: a route planner that reads the elevation honestly, a watch that splits against the route instead of a guess, and a log that tells you — mile by mile — whether you're actually getting faster.
Find the line. That's the whole app. The rest is just running.

"The elevation profile alone is worth it. I stopped signing up for races I wasn't ready for."

"Found my crew through the groups tab. Same pace, same 5am, same bad jokes."

Questions, answered.
How does loopline build a route?+
Draw it on the map or import a GPX. We plot distance, elevation, and grade, and flag the climbs before you run them.
Does it work with my watch?+
Yes — Garmin, Coros, and Apple Watch all sync splits against the route.
Is it just for trail running?+
No. Road, trail, track, and ultra. The same route engine, different surfaces.
Is it free?+
Yes — the core route builder and log are free during beta and stay free after launch.
Does it need a signal?+
No. Routes and profiles are cached, so a dead zone never ends your run.
Can I share a route?+
Yes — build it, save it, and send it to anyone. Your crew can follow the same line.
