You should have come over for a chat.
I managed to go wrong a couple of times, the worst one was at the end where I seemed to head out of Winchcombe on the wrong road missing the school! I think my mind had gone by that point.
Also punctured on that rocky descent near the start and had to watch 1000 of the 1100 riders fly past me. Felt very easy for the first 30 miles but the last 10 was painful, particularly that last rocky descent, I could hardly hold the bars.
Did it in 5:45 eventually, this is the 3rd time I've done the HONC, it's a tough event. Thanks to all the marshals and organisers.
