I've been trying to work on my shorter term power since that's one of my weaknesses. It's often tough for me to get motivated to really drill it for 5 minutes by myself. When I'm with a group it's a lot easier to be motivated to go hard. It may just be a quirk of my personality but I have no problem going at threshold for half an hour up a climb, or riding climbs for four hours at tempo. From the posts I see here it seems like a lot of you do a lot of interval training and enjoy it the same way I enjoy try to beat my record up a 2000' climb. Is that just personality, training what you like riding, or do you do something special to get motivated?
