Strava, what a fun app. After a ride or hike, the activity is transferred from my Garmin to Strava. There, the activity is available for analysis. Of course, speed, elevation gain, all the usual metrics can be seen but within each activity, there are usually segments, for example, a hike from the base to a peak would be one segment where my time to complete the segment is compared to other Strava users. Within that segment would be smaller segments, again with my time, the elevation gain of that segment, the average grade, etc.. all visible. One of the points of comparison is not only how you compared to all Strava users who did the segment but also how you performed against Strava users who I "follow". Had to laugh when I looked at a cycling segment from Sunday's ride and saw who was at #9, lol. He must have been with a group, taking it east.
