I'd say I was lucky!
I had to tease it back into shape/roundness with a vice to get it close enough to build the wheel and keep the spoke tension even-ish.
The
"pot hole" was at the bottom of a nice down hill on a bend, I hit it at about 30-35 mph and rolled the trike, twice! according to the spectators
.
Evidently I was the second person to come off because of it that morning!
I was uninjured but it ripped my pannier bag.
I did a quick (about 3/4 hr) rebuild at the roadside (loosened all the spokes, straightened the rim and re-tensioned/trued, sort of
) then finished the "Sportive" slowly
.
But the brake was very grabby and locked the wheel if I used it.
Weirdly it didn't damage the tyre or puncture, even though the spokes were bowed at the flat spot.
