It's Gonna Be Close!

I went out tonight with TT bars and did a little 12 mile effort to tune it up. I put the effort in in 28:50 which is an average of 25 mph. If I could hold this over the 40K that would put me in at 59:36. Now, I did this with my aerobars but no skinsuit, pockets full of tubes, phone, pump, etc and two full water bottles. Oh, and no shoe covers. If I feel good Sunday morning and prepare well Saturday, I like my chances to go under 60 minutes but it is going to be a squeaker.
