As I was reading though some new on people out having adventure I found a race that is not really like a race but more of a challenge. The event called the Tour Divide Starts either in Banff, Alberta or Antelope Wells, New Mexico and ends at the opposite location. Up until a documentary called, "Conquer the Divide," came out there were about 30 people who participated each year, now there is about 100 people signing up.
The nice thing about this event is there is no time limit and no awards it is more about the personal accomplishment and completing the 2745 miles on a mountain bike would be a huge success. If you are interested in the race check out their website at tourdivide.org.
