I have just done my first TT. Normally I do Gran Fondos. I decided to do the FulGaz TT to break things up a bit. It was a lot of fun. I am not sure how realistic it was. I did a ramp test yesterday with an FTP of 203. I averaged 190 watts on this TT. Not sure if that is good or not.
I think I will certainly do another one when they put one up.
I am 21st in the 50-54 age group so far, so quite happy with that.
