Ah ya, know exactly where you mean. As you say if you had not gone down that long straight hill and turned right instead you would not have been so bad. Bit of a gutter you were so close to the end when you went wrong.
For miles last year I had a right battle with a young lady, I was faster on the climbs but she was faster on the downhills. On the long descent from big stone she had to keep stopping as she was unsure of where to go as I cought up I was shouting out directions to her. She beat me by quite a bit in the end.
