My main Focus is racing 10 mile TTs (UK). So most of my training is fairly short, for example this year I have done 2 rides over 4 hours, my average longest ride per week is 2.5 hours. Through this training this year I have brought my FTP up from 300w-350w @ 80KG.
Having just raced the national 10 mile TT in the UK which was my main goal for the year, I decided I wanted to go and have some fun after months of structured trianing, with near perfect consistancy.
So me and a few friends went out and did a 400km ride. Some portions where fatigue was getting to me, but overall felt fairly strong througout the day.
So this is just to say, as the TR guys say on the podcast, you don’t need to train long to ride long, you just need to be fit. (Also a chance to share my awesome ride )
