If I was asked this question over two years ago, my answer would be very different, but now… I love them!
Bring on the short but steep Dell Rd; Speltham Hill; Lynch Lane; Bitterne 13.5%.
Bring on the final ~0.5 miles up Harvesting Lane.
Bring on the Bell Hill cat3s just north of Petersfield; full Old Winchester Hill; climbing to Butser Hill summit from the Butser Ancient Farm.
Etc. Etc.
Currently turbo training to further improve my estimated FTP before hopefully tackling my first cat2 hill this year, Bwlch Y Groes. 😈
