I envy you. I've been training for the Big Dam Bridge 100, and I'm still taking 4 hrs and 45 minutes to do my 50 miles test run.
That's too slow and they will cut me at the 50 mile mark if I can't chop 45 minutes off that. I hope that the course is flatter than my test course, but they are just across the river from each other, and have about the same elevation spread of about 400 feet between highest and lowest points and they are both mostly in the foothills of the Ouachitas. So I'm not sure what will happen.
