gelled strobe down low left of the photographer and another strobe on the ledge to the right of the skier shooting up. not sure about the light on the pipes but could just be a speedlight zoomed in.
RX a low to the ground left, behind and about 45 degrees off the angle of the camera, gelled pink
RX camera right, pointed pretty much directly at the wall and skier, 90+ degrees off the angle of the camera.
Speedlight, probably some sort of modifier (snoot?) a little to the right of the first RX.
shot with a 1d and the 24mm f1.4 because if I had the gear you had and I wanted this shot I would feel like a boss with this combo in my hand. And that's part of the fun.
