The bike fitter indicated that my seat was the proper height and in the proper position. The only thing I've changed this far is the cleat postion.

I do have tendonitis in my left ankle (the three tendons that run behind the ankle bone on the mediasl aspect). It felt fine all week so I opted for the century ride yesterday. It may be as you suggested a form issue for I could not get comfortable in my saddle all day. By the end of the ride my l left ankle was really talking to me. I woke up this morning to the right ankle whispering some. This is my third century this year and the previous two went off without any problems. So I'm a bit confused as to what happened yesterday to make for such a long and uncomfortable day. I would like to resolve this for there is a century in two weeks that I would love to do but have to resolve the issues on hand first.
