Ok so this is my 2nd year of training and my first year with a power tap. I have got all my base miles in and I've been working on L3 once a week and L4 three times a week. My FTP is 253w and I can spend 2hrs. right is the middle of L3 witch is for me 213w. Should I try and work for 3hrs. or just put more time in to L4.
TIA
