Well, if you were ever going to DNF a ride, it sounds like you picked a good one.
FYI, for various unusual circumstances, they can sometimes extend the time on intermediate checkpoints. If you're running late on an intermediate checkpoint, but still in good shape to go on, keep going and worry about it later. I'm not suggesting y'all should have done it there, but something to keep in mind for the future.
