Calories during long runs

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.

I’ve only done ultras up to 50 miles and luckily have an iron stomach...but, late in the race is when I’m really craving real food: PB&J, soup, etc.   I have tried Ensure too and it definitely hits the spot.   

This is embarrassing but the best thing I’ve ever eaten late in a race was Doritos and Mountain Dew.  Just tasted so good!  

I've done multiple ultras but nothing further than 50 miles. I have a sensitive stomach as well and have found Tailwind works great for me. A few sips of Coke later in the race can help settle my stomach as well.

Agree with @Elena - my go to is always Tailwind. That and I've recently started using Spring energy and found them really easy to digest and keep down. 

The longest ultra I have done to date is a 50 and I have had the best luck later in the race with lemon Larabars, tailwind, coke, broth, bacon, and potato chips. I am training for a 100 so I will have to get back to you on what works for those later miles 🙂

Lara Bars have been a training and early race staple for years. Those bars have been gradually dying out for me. The only ones I can still do are blueberry, cherry, lemon, and lime. I usually can't stand them anymore past about mile 30. At Mohican, I grabbed a bottle of Ensure from my crew early (about mile 14) because I was feeling low on energy for whatever reason and ended up sticking to mostly liquid calories the whole rest of the race. 

I've got a few 100ks under my belt (no buckle yet, though!) and while I try to start with honey stingers and picky bars, homemade pb&J, and muffins... Torwards the end I do like to have beef jerky or bacon, and lots of coke and ginger-ale to suppliment the norm. I have done a few 50 milers with tailwind and honey stingers, but personally get really tired of it.  I have used ensure during my last 50 and my first half ironman.


Best of luck at your next race!
