I've just found this site, so sorry for the 2 month delay. Although being a postie I still class this as quite a prompt reply.
It was my 1st sportive and I really enjoyed it. Re hill, assuming you mean Harting Down that's hellish, I'd ridden up it a few weeks early so knew what to expect, it just keeps going on, admittedly I've not been back since!.
I had a great time in a big chain, resulting in me having to 'hang on' for the last 20 miles.
Which leads me to my reason for posting:-
The guy that drafted me for 2-3 miles with on 5 to go, I was spent had nothing left, but he stayed there until someone better came along, grrrrrrrrr I was so angry.
