Run Log — understand your run

Run Log — your run, explained

Drop in a file from your running watch and read what actually happened<br>during the run: what changed, where it changed, and what might account<br>for it. Run Log reads FIT and GPX files, shows moments rather than<br>averages, and shows its working for every claim it makes.

Nothing is uploaded. There is no account and no server — your file is<br>parsed by your own browser and stays on your own machine. Run Log is<br>free and open source.

Run Log needs JavaScript to read and draw a run, so please enable it to<br>use the app.
