Its really amazing how easy it is to complete a 100 km ride with a nice bike and constant practice

Wheels of Happiness

Am really amazed how easy and efficient it is for me to ride 100 km lately despite an advanced age.   Constant practice, and a well built bike:   nice GS and WS make for effortless ride.   And pacing yourself well.  

It takes 3+ hours to complete the ride, whereas before it takes 6 hours or more.
