Just a dumb question for you... on any of those rides did you happen to notice that your foot got a good case of the shakes at random...perhaps while screaming down a hill that was so great your foot just shook. While in awesome shape (both running and cycling) I did a road ride where I got a good case of the shakes on a down hill. I really didn't think a whole lot of it, it stopped at the bottom and was not at all a problem..just a shaky foot on a desent.....until my achilles swelled up so bad I could hardly walk for the rest of the week. Switching which foot is forward while decending will stop the shake if it comes back. Just thought I would share.
