Thanks, that last video was very long and listed alot of mistakes that people make and lots of tips to make sure I have to correct form.
I cycled again today, I completed my circuit in my fastest time but I had this massive head wind for like 2K's of the ride, I was riding down hill only going about 10k's an hour and pushing real hard in a low gear (dam, wind tunnel of a bike path next to the motorway). To combat the wind I try to get down into an aerodynamic position which involves the bending of my arms, to prevent my arms bending too much (and hurting) I slide back on the saddle, really far back. What can I/should I adjust??
