Also, while the exact route information is apparently a closely guarded secret not to be revealed until we check in the day before the race, we do know that it is roughly the same as last year's course except in the opposite direction. Simon, the super posting TR veteran from Vancouver has posted the following breakdown based on reversing the numbers from last year.

I did the metric to english conversions and Day 5 is even more intimidating than it seems in metric. It breaks out to 67.6 miles and 8,528 feet of gain. The good news is that those numbers are almost exactly the same as my Day 3 on the Kokopelli Trail so I know what that is going to feel like. It's not going to tickle.
