I am stupefied that most all of these goals involve the quantity of riding rather than the quality of the rides.
Unless it is implied that more = faster, I don't see the point.
When people ask me how far I rode that day I say "I was in the saddle for 4 hours, not I rode 80 miles"
Why are we so caught up on miles?
If I had to answer this thread it would state: to stay on more A rides.
