OK so i've been out for a spin on teh road bike for the first time in a while, thought I'd start at 10 miles, nice and easy, a bit hilly but nothing much. Averaged 15mph which isn't great! but as I can happily hold a steady 20-21 on the flats without dying, I can only assume the fairly short sharp hills are what killed my average, and certainly I was dropping below 10 at times. I just don't seem to be able to keep the power going up the hills, either I can maintain the power then crash and burn half way up due to lung failure, or I back right off and crawl up it.
I'm not a fitness person - am I needing to improve my strength or my cardio side (probably both but I feel it may be cardio related primarily due to my ability to give a short burst easily). Repeated hills? Longer low intensity rides? What's the advice?
