Bain De Sang is a 9a route in Saint Loup of switzerland that was climbed from Fred Nicole for the first time in 1993. Since then this crimpy wall has seen some repeats from strong climbers like Manolo, Scarian, Graham, Pou, Lammberti, Rouling and the female fenomenom called Josune Bereziartu
Some climbers like Iker Pou disputed about the grade of the route saying that it seemed a grade easier than the benchmark 9a route, ''action directe'' but Fred Nicole said that the route has ''changed'' since he and his brother climbed it in 1993.
