Strangely, the Skater actually seems to struggle on this level. There are many twists and turns, and there's no telling how far the ramps will fling you. So sadly, he isn't a recommendation for this level.
The Runner has above average everything, meaning you can simply navigate through the level. Take advantage of how far forward you can see into the level, and plan changes from there.
The Lizard jumps a lot higher, but it will not go as fast as the Runner, meaning all jumps need to be taken at the end of the ramp, and it will fall quite fast, meaning gravity has to be changed to another side of the tunnel. Slowly edge your way through the level, and the Lizard becomes an option as well.
Overall, this level is a little harder than the ones surrounding it in the Winter Games, but not much of a problem to most players who have come this far.
