24 hours to my first vertical climb - Vail, CO

Sitting in the airport at Dulles International waiting for our flight to Denver.  Really looking forward to the beginning of our vacation.  But before the vacation, I thought about signing up for a La Sportiva Hill climb which is 7.5 miles and starts at 8500 feet in elevation and ends at 10,300.  Yea, for a guy who runs races at 1,000 feet elevation, this should be a hoot.  I can only imagine what I will be feeling like by mile 5..I bet the lungs will be burning....well, boarding in about 20 minutes so will check back in later this week...I'm out.
