Cropping an activity on Strava

When you’re hiking, cycling, climbing or doing other sporting activities it is easy to forget to stop tracking an activity. When you’re at home or static this is less critical. When you get into a car after a hike or other activity that mistake will screw up your average speed and other data.

Yesterday I realised that I had forgotten to stop tracking on my Suunto device and on my apple watch. With the Apple watch this was less important because it logs individual climbs. With the Suunto device however it tracks the speed of the drive as well as the increase and decrease in altitude.

Strava has two options to fix this mistake. Split is good for running and cycling activities. It allows you to split and then delete what you do not want to keep. Crop allows you to select the in point and the outpoint of an activity like you would if you were editing video.

In the image above you can see the track from the climbing gym towards the motorway. Initially I adjusted the sliders simply to remove that segment but noticed that there is a more precise tool.

With the climbing profile view you can see each climb as well as the difference in altitude as you drive from the car park to the motorway. I deleted the superfluous data and pressed “crop”. I then had a clean export of my activity.

This is a quick, intuitive and useful feature to know about. It allows you to keep a more accurate record of previous activities and a more reasonable track of distance covered over the last week, month or year. Some day I might go back and clean up previous activities.
