I'm not going to suggest Silverdale for tomorrow in case I put a curse on the weather - we'll keep it to 9am Denholmgate, 9.30 Keighley and take it from there.
MTB alternative option - 9am from Co-op car park in Hebden Bridge - give me a ring/text if you are thinking of coming. Route will involve going 'over the hills and far away'. And a cafe stop, hopefully. Ian.
