Boredom? If you are past age 10, that's an interesting mental choice.
Not as stimulated as you once were about one of your regular routes? Ok.
Now in my 8th week training after 5 years of bicycle retirement, my 4 and 5 hour rides fill my mind with challenges, scenery, plans, working on my breathing, other.
When I'm really working hills are hard intervals, my mind really gets free. Photo is of one of my most "boring" routes...
