I'm not sure how many ultra/distance runners are on here yet, but I figured I'd ask anyway: what is your go-to for calories late in long races? For me, someone who usually loses their stomach late, I've had a lot of success with Ensure. I grew some apparently long term palate-fatigue with that during the Mohican 100 a couple weeks ago, so I'm experimenting with CarboPro and hope that works for my next race in early August.
