Dumb question time....So I am pretty much a newbie when it comes to TT racing. I am an avid road and mountain biker and put in a few thousand miles a year. Earlier this season I got in a few 10 mile TT runs. I was riding my carbon road bike with aero bars and doing avg speeds of like 21-21.5. I decided to get a TT bike and have some fun with it. I went to a local tri shop and got an entry level Quintana Roo Tequilo. Made a few upgrades, nicer wheels, etc. Anyway, I had a professional fitting and did a TT the next day for my first ride on the bike. Yeah, I know that wasn't brilliant, but I figured what the heck right...
First thing I noticed is that staying in the aero position for even ten miles isn't exactly second nature. It is going to take some practice to get comfortable like that. I seemed to have a bit of trouble with air intake. Is this normal or maybe a "fitting" issue?
Secondly and what I thought was a bit strange is that like 3 miles in, my legs felt like I hadn't been riding all season. On my old bike, my legs were never an issue. It felt like it was the beginning of the riding season all over...the next morning, my legs were sore...something that never happened before.
My guess is that the position of the TT bike utilizes different muscle groups? Is it for power, endurance, something else?
