Great tips! Fueling was the one aspect of 50ks I had down, thanks in large part to my cast iron stomach. I try ALLL the new foods on race day! 😆 My last 6 hour race, I waited until mile 14 to start fueling, and I performed terribly and didn't meet any of my goals. Lesson learned... don't get complacent, pay attention to the details from the start.

I like these video focusing on nutrition and it seems that few ultra distance runner are not eating enough . Great content as always , thank you for sharing Claire these top athletes advice .

Loved this one! I'm 2 weeks from my first ultra and this really helped!

Great video ! I plan to share this with alot of my endurance runner friends.

you don't need lots of carbs if you are fat adapted, maybe Scott is running at higher intensity (definitely is) but if I eat carbs I get sick, so I mostly eat fat and protein.

Where do we stand on using Tylenol or Ibuprofen during ultras?

What about folks who have 20 grams or less of carbs per day (no grains, just a few berries)? Becoming "fat adapted" allows you to effectively burn body fat or consumed fat (zero seed oils, only animal fat or butter), but only if you do not raise your insulin levels by consuming carbs.. Fatty beef and eggs, repeat. Don't feed the bad bacteria. It wasn't until after I turned 60 that I found the low-carb folks and fixed my gut issues. My primary issue is electrolytes. It is so expensive I try bulk components from amazon. But they all look the same and I don't know if I can trust that the contents are what they say are. White powders from whatever origin. Always terrified it is some toxin from China. Is this okay?: (potassium citrate, magnesium citrate, calcium lactate, mined salt)
