With regards to paying for the event, I've split the difference. I think 15-17 quid for a mostly unsupported ride is expensive. However half that is acceptable, so I pay for the Man-Blackpool run, and then ride the later Manchester 100 as a freebie.
My attitude entirely. I feel a bit sorry for those who are gullible enough to pay charlatans like Bike Events every time they go out with them. I only know this from my experience of bitter disappointment after actually paying these cowboys and receiving....well nothing really. Several charities who had been involved with them have expressed resentment to them and refuse to be involved with them again.
