A map of every street you have ever run
Training apps are good at the numbers for each run. They are not good at the bigger picture: where, across years, you have actually been. A cumulative map shows every street you have run together, and the dark gaps between them.
The loop problem
Most runners have three or four routes that fit their usual distances, and they run them for years. The training is fine. The scenery is not. A cumulative map makes the rut visible: a handful of bright loops and a whole city of dark streets around them.
Once you see the gaps, it is hard not to fill them. An easy run becomes a chance to take every side street on the way out; a long run becomes a trip to a neighbourhood you have never seen.
How it fits with a training app
You do not have to choose. Keep using a training app for pace, splits and heart rate, and run a cumulative map alongside it for coverage. FOG records in the background with the app closed, so there is nothing to start or stop.
If you already have years of runs recorded, export them as GPX and import them into FOG with FOG Unlimited. Every old run appears on the map at once.
Run ideas that light up the map
- Grid sweeps. Pick a block of streets and run every one, back and forth.
- Out new, back old. Take a fresh route out and your usual route home.
- One neighbourhood a week. Finish it completely.
- Trails and river paths. Long, clean lines that join separate parts of the map.
For more ideas see challenges that are not step counts and GPS art.
What FOG tracks
The ledger shows the area you have unfogged, the distance travelled and your share of the Earth. Ranks climb with area. The collection fills with the countries, regions and cities you have been in, which makes races in new places count twice. Walk cards turn a finished outing into a shape you can share.
No account, no cloud, no ads. The map stays on your phone, and you can export it as GPX. It is a phone app, on iOS and Android.
Questions people actually ask
Does FOG work for running?
Yes. It clears fog for walking, running and riding.
Can I import my old runs?
Yes, with FOG Unlimited. Export your runs as GPX and import them.
Does it replace my training app?
No, and it does not try to. It does not record pace or heart rate. It maps coverage.
