Sometimes it is nice to ride alone although I get bored over 40 miles without company. I still prefer to ride with my speedy DH but he uses it as easy days in the midst of race training. I can do long rides with him but it is turtle paced. Example he did a mountainous 85 miler in 6 hours pedal time (including slowing for me when on the flats), it took me just shy of 8 hours. He can climb, I can make it to the top and that is all I will claim.
