DK Summit, (called DK's Snowboard Cross in Europe, Japan and Oceania), is a track in Mario Kart Wii. The biggest threat on this circuit is the pink, sludgy snow that'll slow racers down to a crawl if touched. After you're launched out of the huge cannon, note the blue half-pipe pads dotted along the wall though - you can chain boost off these for a nice chunk of the course. Similarly, when you reach the skating Shy Guys, do the same thing, paying particular attention to the diagonal tracks in the snow which give away the perfect racing line to take. Alternatively, if you have a speed boosting power-up of any sort, simply blaze down the center of this half-pipe, overtaking pretty much everyone in the process while they mess around trying to avoid the pink sludge.
