You wanna bet? Last weekend, taking out the 10 minutes of single leg drills at the end:
And that includes 39 minutes of riding inside the city.
Less than 1% / 60 seconds coasting on 6867 seconds (1 hour 54+ minutes) of zone2 riding.
And the weekend before that I made a Strava moose for @Scheherazade
and at 3 hours and 22 minutes I stopped to briefly chat with a neighbor, up to that point it was 1.4% coasting (2 minutes and 56 seconds) from a couple of stops while leaving (16 minutes) and returning (38 minutes). So I think ~3 minutes coasting while spending 54 minutes in the city is pretty small, relatively speaking.
