I don't know why people don't review such products more when it is a very important part of our training prep. I bought SiS and Maurten and will be experimenting over the next few months, so this content is very helpful
1) Isn't fructose the main culprit for gut issues? 2) Isn't a 1 : 0.8 ratio increasing the amount of fructose consumption? What is your take on nutrition in ultra endurance events like ultra marathons or full distance Ironman?
Hey, good questions! So: 1) while fructose can cause GI upset for some, I wouldn't say it's the main culprit. More often than not it's something else. There are a few other studies (not just the one mentioned in this video) that suggest that glucose co-ingested with fructose reduced the prevalence of GI symptoms compared to glucose alone in the atheltes investigated. 2) yes it's increasing the amount of fructose consumed, but with the above point in mind that shouldn't matter 🙂 As always it's about practice. You should always practice race nutrition before the event and it should be possible to tell whether it's specifically the race nutrition products you use that are giving you gut issues. Truth be told, nutrition for an ironman and ultra distance races follow the same principle as general carbohydrate intake guidance for racing. Depending on the race and the conditions, priority may shift (eg. Hydration over nutrition, nutrition over hydration) and the race length and intensity might influence food choices (eg. Solid over gels). I did a video on carbohydrates per hour for racing, and this could be used as guidance for an ironman and ultra distance events too.

You're welcome, glad you found it helpful 😊 and obviously I agree with what you mentioned about training prep 😉
Thanks for the video! Going to try our the SiS product for a race this weekend instead of my usual Maurten.
You're welcome! I wouldn't usually suggest trying anything new on race day, so practice it first! Good luck with your race 💪
Another awesome topic. 👍🏽
Thanks Andrew!
