A quick experiment to figure out how many times I've summited a small local mountain given my Strava activities. More details here.
Given a bunch of GPS activities and a polygon defining the area of the summit, find all activities that contain successfull summits.
Special consideration is given to:
- Activities where ascent and descent were recorded separately.
- Multiple summits within a single activity are counted individually provided a minimum distance between subsequent summits is covered.
Total number of activities: 777
Total number of summits: 60
Activities with summits: 57 (48 runs, 9 hikes)
Shortest: 8 km, longest: 59 km, mean: 21 km
Lowest elevation gain: 363 m, highest: 1881 m, mean: 719 m

You need node with npm.
Install dependencies:
npm install
Download from Strava and analyze:
npm start
Only download:
npm run strava
Only analyze:
npm run analyze
Analyze included example file:
npm run examples
There is a script to download all your Strava activities. Alternatively, you can skip Strava and supply any other GeoJSON file containing a collection of line strings, e.g. the included data/examples.geojson.
For Strava, you need an authorization token. You can get a default public token by creating a Strava API app (follow this). To be able to access your private activities, you need a private token (follow this).
Put the token in a file called stravatoken.
The Strava API is rate-limited to 600 requests every 15 minutes. If you have more activities than that, you may need to run the script in batches to download them all.
