Only a few of the tracks I have registered in Runkeeper was taken in City strides.
Looks like you might be Martin H. Hamstad - CityStrides
I was initially going to ask if your activities in Runkeeper are tagged as Running/Walking/Hiking … but decided to take a moment to check some data out.
Runkeeper is telling me that your account only has 13 activities in it.
The Runkeeper logo on your profile is a link that goes to Martin H. Hamstad's Activities - Runkeeper … is that your expected Runkeeper account?
