Update (9-5-10): Report on final results
In what is the swan song for the Grand Teton 100 (the other distances will continue), 2010 Leadville 100 winner, Duncan Callahan, and 2010 Vermont 100 winner, Andy Jones-Wilkins, have run to a near draw halfway through, with Callahan taking a slight lead heading out for the closing 50 miles (live results, lagged).
Ty Draney's 2009 course record of 19:19:51 is on the line (as are eternal GT100 CR bragging rights) on what is turning out to be a warm day at the Grand Targhee Resort.
The GT100 races over a 25 mile clover leaf course, with about 5,000 vertical feet per lap.
1. Duncan Callahan 8:30
2. Andy Jones-Wilkins 8:31:30
