Oh well. I doubt that will ever happen. I do 4-5 TTs a year. I hate stretching but I do have pretty good core strength now. I love TTs, but not as much as I hate to stretch. I do it for my back already, so I'm not as un-limber as you would think.
I was hoping a change in position on the bike might help, but you're probably 100% correct.
