I once thought it'd be a good idea to take my fix to Cornwall. Hadn't been riding fixed long at this point, and wasn't in the best of shape. Rode to the train station, got on a train, arrived near St Ives. Then remembered what bastards the hills were. Went up several stupidly steep hills at about 2km/h and then struggled to keep control spinning out down the steep approach into St Ives. Not the best idea I ever had. Bike remained idle for the rest of the week...
