It's really easy actually, its not really a obstacle course- its a maze- so you just step on places where there isn't much ice (i did that) and then you won't slide. then work out where you will slide on the piece of ice you will step on, that helps, and then keep on doing that. or if it is the WATER one (i never remember which gyms they are hee hee!) then keep stepping on the tile's to make the water go up and then down until you reach the gym leader, really easy, both of them! hope i helped! teehee!
