Hey crazycanuck: I'm not quite sure what type of cleats you have. Do you have the "Ritchey"(small & narrow) type cleats? or the "Look" wide/with 3 screws-type of cleats?
If it's the small "Ritchey" type you may be limited as to how far forward or backward you can move these types of cleats.

If you have the wider platform cleats, start out by;
1. Loosen all the screws, move the cleat to the center. Tighten your screws back up. Go for a ride or use your trainer to pedal for a while.
Move your cleat forward or backwards until your pain goes away.

A: Note: Since your left leg is the only thing hurting your seat may be too low.
In my case, my right leg is shorter than my left leg so I made this neoprene rubber spacer about 1/8" thick and placed it under my right cleat. This helped me out, I stopped rocking in my seat.
I wrote about cleats verses straps on my blog:

Hope this helps.

Best regards,

Greg

I have a nice new pair of shoes & can't get my left cleat into the right position. ( I can't remember how i had them on my old shoes..) I don't know if last night was just a bad night for cycling but the left side of my left knee hurt so much that I had to take the train Right leg is fine..

I am picking up my new saddle tomorrow and am wondering if I should see the same person who set up my bike to help me out..

I'll keep playing with the cleat position whilst doing some spin stuff on my bike inside..

Thoughts?
