Love this feature in Strava.
It’s obvsiously really simple for software to do this and takes any hassle out of having to deal with the data yourself.
And of course makes for pleasant reading if your speed is improving. Aiming for 16-18mph averages. Currently I’m probably at about 15mph on most. I think I’m maxed out on downhills (as least safely), could do better on the flats, but the big area of improvement has to be all the climbs. Currently I’m only clmbing at 9-12mph.
