The early climbs: Duncan Ridge and Coosa Bald in the dark
You start at 5 AM and almost immediately the course points up. The opening stretch runs the Duncan Ridge Trail toward Coosa Bald, and it is no warm-up: the first eight or so miles stack several thousand feet of climbing, including a long pull of around 2,300 feet up to Coosa Bald. The footing is rugged, rooty singletrack, you are doing it by headlamp, and the climbs are steep enough that you should be hiking the hard pitches from the gun.
This is where the race gets lost before most people realize it. The temptation is to push the early grade because your legs feel fresh and the field is bunched up, and that is exactly the trap. Hike the steeps with purpose, keep your effort honest, and treat this block as the price of admission, not the place to make a move. Burn matches here and you will have nothing left for the gravel and the back half.
