I stayed seated on climbs so I've not had experience with this. If you don't do something to maintain speed as you stand, it will, to the rider behind you, likely appear as you have shifted into reverse; you'll hit the trailing rider's front wheel in all probability. That generally puts him on the ground, hard.
