invisible goblins with hammers

i'm the guy in the front.

it was the 3rd run of the day. just shakin loose cobwebs and warming up. not riding aggressively or even doing anything hard when (right around :30) my bike suddenly decides to spontaneously abort the drive train. rear derailleur was shorn in 2 and shot off in multiple directions, chain kinked and twisted beyond repair, 4 spokes blew out.

i'm not a new rider, was on a capable machine that gets regular care, didn't not clip anything, hit a rock, shift gears. aside from invisible goblins with hammers, i have no idea what might have caused this.

any ideas?

Sounds like it's a chain issue. Either a stiff link or perhaps more probable a rivet that weren't properly seated.

Weird. Rear derailleur into spokes?

Could have been a stone or stick flicked up and jammed in the chain?
Maybe the derailleur had been damaged in a crash previously, so was weakened?

sometimes these things just happen.
