What did ou do with the rest? Bury it?
Anyway, HBH is the easiest one. Lets say it is 500 metres long, you have a steep 80 metres to start, but then you get a nice breather. Then you have 200 metres less steep, and then a breather. And then the rest, which has 1 steep bit just before the end.
I was so scared the 1st lap that I did the right turn and shifted both mechs right down, so my chain did fall of. I then managed even the steep bit from a standing start. Wasn't worried about the other laps.
Just think about the feeding station on top and the nice decents.
