Mile 45 this happened!

Lack of communication meant that while the head of the pelaton was slowing down....the rear of the pelaton (Andy Lowery) was speeding up to nearly 30 mph.
Laws of physics say this won't end well. Swerving to avoid Dominic, Andy was launched high into the air, landing with a thump stroke crunch in the carriageway.
Suspected broken/dislocated shoulder & collarbone meant he couldn't continue.
