At the Red Bull Hare Scramble this year, there was a certain part of that track that caught a couple riders off guard. Er, a couple dozen.
As you can see, the edge of the narrow track to the top of the mountain was a fairly steep and deep pit. Unfortunately, it was very difficult to avoid. Rider after rider fell to the same fate in a hilarious/pathetic pileup.
One can only imagine what they were all thinking down there...
