What is Summit Bag?
Summit Bag is a peak-bagging tool that automatically identifies the peaks and cols you've reached from your Strava activities. Connect your Strava account and it checks your rides and runs against a database of over 500,000 geographical features, building a collection of every summit and pass you've crossed. No manual logging.
The catch on the free tier is worth knowing up front: only your 100 most recent activities are processed. If you have a decade of hill days on Strava, the free version will show you the tail end of it. Premium at $20 a year is what unlocks the rest of your history.
It's a one-person project, and the developer says so plainly on the upgrade page.
Key Features
Automatic peak detection
Summit Bag checks whether your activity's route line passes within 70 metres of a known peak or col — a wider radius for a handful of popular peaks whose summit location is disputed — so summits get detected with no manual logging. In the UK and Ireland it draws on the Database of British and Irish Hills plus OpenStreetMap; everywhere else it uses named, height-tagged peaks from OpenStreetMap. The database syncs with those sources roughly quarterly, so a peak you add to OSM today shows up here in a few months rather than tomorrow.
Col recognition
Beyond peaks, Summit Bag tracks cols: the low point on a ridge between two summits, which is to say a mountain pass. That's the half of the product aimed at cyclists, since a Tourmalet or a Madeleine is a col rather than a peak.
Interactive map and list views
Your summits on a map or in a sortable list, from a lifetime view down to a single region. Premium adds a 3D satellite basemap.
Strava activity descriptions
Summit Bag can append the peaks you bagged to the activity's description on Strava. This is off by default — it's the reason the app asks for Strava's upload permission — and you turn it on yourself in settings.
Groups and leaderboards
Anyone can build their own groups. Leaderboards are Premium: top 100 athletes for a group, top 10 for an individual peak or col, covering the current and previous month.
Manual bags
Premium users can record a summit that never made it onto Strava, from the individual peak or col page.
Who It's For
- Trail runners and hikers working a list — Munros, Colorado 14ers, Adirondack 46ers, a local set
- Cyclists collecting cols rather than peaks
- People with long Strava histories, who are also the people most affected by the 100-activity free limit
- Not people who want a standalone log. Peakbagger has its own database and manual logging; Summit Bag's whole premise is that Strava already has your GPS and should do the work
