Road bike or mtb w/hp slicks, flat pavement, no wind, just cruising along at that certain speed where you're comfortably within your aerobic envelope/comfort zone - not dawdling, not hustling - just feeling good... the pace you could keep up for 3-4 hours...
You look at the speedo. What does it say? How old are you?
-------------- 15-16 mph 64
A little over 20 MPH in Myrtle Beach, at a normal pace on a two hour ride. (Around here nothing's flat for more than 100 yards.) Age 41.
BTW, the fastest guys in our club are all older than me.
