Went with some friends at the weekend. Got absolutely blackened with mud on the canal path. Having a white bike at least makes it easy to identify all the bits that need cleaned (ie, all the bits).
Stopped for satisfying lunch at the Bridge Inn, Ratho. Had a pint of the Summer Storm. I'm not normally a wheat beer fan but I couldn't resist the name given the weather we'd been riding through.
Stayed out late in the end and got the train back from Uphall. If I do it again I'd look for a different route as I don't have any bikes that are suited to the alternately rough and claggy terrain along the canal.
