Morning ride

A Sunday morning is perfect for an early morning ride. Started at 6:30. Not bad for an evening person.
Unfortunately I ran into technical problems after 3 hours. A sideplate of the chain snapped and got stuck in the rear derailleur bending it inwards enough to get it stuck between the spokes of the rear wheel. The wheel and frame are intact but I need to replace the derailleur, the chain and the derailleur hanger.
