Here's a different kind of race. On June 20-21, 2009, the 1st Red Bull Road Rage downhill race was held in Italy, in Cortina d'Ampezzo. The event is a 5 km downhill race, on an asphalt road, with contestants competing in heats of four, starting with 100 and racing over two days until the final eliminations.
The course has 13 hairpins and descends more than 400 m in the 5 km. Here is what it looks like:
The winner this year, ex-pro Mauro Bettin, clocked in at a top speed of 98 km/h, or 60.9 mph. I have personally ridden at 90 km/h on the Scenic Highway in West Virginia and there is no way that I could do it on a road like this! I personally cannot stand the flavour of Red Bull but I have to admire their marketing instinct. It must have been an amazing event.
