We hear a lot about bicycling having health benefits forthe one doing the bicycling. Yet a lot of CASUAL bicyclists are not all that healthy.

So, in order to gain NOTICEABLE health benefits from bicycling:

1a. How long in time does each ride need to be?
1b. What intensity does the bicyclist need to reach?

Well, there's this:
http://www.nhs.uk/Livewell/fitness/P....aspx#moderate

They say "at least 150 minutes of moderate aerobic activity such as
cycling or brisk walking every week" or "75 minutes of vigorous aerobic
activity, such as running or a game of singles tennis every week" plus
strength exercises. Following links from that page tells you that flat
riding is "moderate," fast or hilly riding is "vigorous."

So 10 to 20 minutes per day does it, depending how fast you are. And I
suspect most of us here would be considered fast, even though most of us
are probably slow by our "used to be" standards.
