Just after Foxton, climbing up one of the steep hills the rear hanger on my bike gave way throwing the rear mech into the spokes, which bent the mech. After a few minutes pulling the mech from between the spokes I resigned myself to walking the rest (3 miles) of the way home, although that was helped somewhat for the first 1/2 mile by freewheeling down the slope to the coast.
Fortunately there was time to get the bike up to cyclelife in Alnwick, who sourced and replaced the rear hanger and mech.
When I picked the bike up I managed to get a staple through the tyre & get a puncture, fortunately when I picked the bike up I also bought a spare inner tube.
