And, I don't like riding alone...I wish I did.
That's a challenge for me too.
I have been riding alone lately though... on a 24 mile loop/bike path... and it has taught me how to keep my average/speed up without someone pushing me.
It's been a good learning experience.
BUT.... I refuse to ride the city streets alone. I'm all about safety in numbers.
