Sorry to hear you scratched Alasdair!
I rode some of the course with this man the last couple of years, and he did an amazing job of finishing last year, despite starting off with a nasty cold. He looked like death warmed up that year at the start!
Did you go out too hard this time? I know you had wanted to better your time. Bad bonk two days in a row, and the weather sounded bad, plus a twitchy knee, not a good combo!
At this stage in the race, it gets really really hard. Being exhausted, and there area lot of hard walking sections all the way down the West coast. If you are carrying any kind of injury, it is not good.
