You really want to let some uppity 63 y.o. like me ride circles around you,
then go ahead and stay at home. Otherwise get out there and ride.
I have no motivation issues once I get on the bike and start pedaling. However it does take some effort sometimes just to get off my duff. It does help when someone else asks if I want to ride or even when I ask them.
Most of my rides are solo though. So many times it's just I know that for several days after a 1-1/2 to 2-1/2 hour ride I'll feel really great.
