Well done.
How did you do it?
Did you follow Bold's advice re gears and tempo etc?
Yes! I started in 5th gear and went down to 4th about half way up. Stayed in my saddle the whole way up except the very steepest sections. Most unlike me as I usually attack hills standing up.
Slightly concerned about my bike. It was creaking a lot. Think I need a new chain, brakes, gears and god knows what else.
