I should not worry about the Brian Robinson (after all he is over 80). It is only about 78 miles and everyone starts off together for the first 6 miles of closed roads before the climbing starts. I am going to use it as a test event after my recent injury and if I can get round at all I shall be satisfied. The weather will be a big factor, since Saddleworth Moor is a pig most of the time and we were very lucky last year with perfect windless, hot conditions.
Nevertheless, the weather is something that every rider will have to endure and a bit of 'Flandrian' spirit will go a long way.
