The group I was with fell a couple of hours behind my pace. So I was doing the same. Jumping on the wheel of pickups and solo’ing it.
I totally did a gas station stop at the last 20 and chugged a 20oz of coke. 
My hands, too, were the most noticeable. I thought I had blisters, but they were just really sore.
Considering how many repeat faces I saw along the way riding at the same pace, I’d put money on us crossing paths.
