Yes, that's happened to my bottoms as well. There's a rough-edged hole encrusted with blood and tissue on one side and gritty soil on the other. They weren't new but they were/are perfect for this weather with having reflectors on the back and being so warm all over (apart from the ventilation in the knee area of one leg).Ouch. I did that last winter. Apart from it being a bit ouchy, I tore a hole in my brand new 2XU running tights which was annoying!
