Hey! Glad to hear 😊 I know you asked the best way to refuel, but there are quite a few factors to not feeling fatigued after that sort of run. In a nutshell 1) getting your pre-run nutrition right 2) consuming enough calories during the run (if running >90 mins) and 3) optimising post-run nutrition. You can find a link to a video on recovery nutrition and protein below - hope it helps! kzfaq.info/get/bejne/eMV8ebWInrHDd4E.html

The 10g/kg carb load rule surprised me a lot. I have my first half marathon coming up and I was curious about your thoughts on electrolyte and isotonic drinks. Do you have any specific recommendations? And is it best to drink them before, during or after the event and how much in advance/after? Greetings from Antwerp, Belgium
@NutritionTriathlon 10 ай бұрын
I think it surprises a lot of people 🙂 Before a half marathon I'd recommend a drink with electrolytes, chiefly sodium, with your breakfast, probably something like 2-3 hours before. This should contain around 500mg sodium in 500ml of fluid. That should be enough hydration wise to cover you across the race. As for whether you consume any drinks during the race, that's down to personal preference and how long it'll take you to complete it. You shouldn't really need hydration as such over a half marathon, drinking to thirst is fine because it's a relatively short race. For example, you could just use gels and only consume small amounts of water to thirst. Afterwards I normally recommend about 500ml of fluid every hour for at least 2 hours, and again 500mg of sodium per 500ml of fluid is good for rehydration. Then you can be dictated by thirst. Hope that helps!

Thanks for the tip! I’m 2 weeks out from my first half marathon(first race at all). I am a weightlifter and finally decided to take up running haha. Im pretty heavy 5’9 255lbs. Should I adjust the 30g carb amount during the race you recommended based on my size or just keep it the same. My target time is 1:55. Thanks!
@NutritionTriathlon 2 жыл бұрын
Hey, you're welcome! Great to hear you've got into running, I hope you enjoy your first half marathon! 😃 Good question! I would say it's probably worth just sticking with the 30g per hour (so 60g overall). Firstly, that should be enough if you've eaten well in the days before your race and eaten a decent breakfast. Secondly, if it's only two weeks away then it's probably better to err on the side of caution with regards to nutrition. Ideally you'd want to practice your nutrition strategy at least 6 weeks out to make sure you can tolerate things okay and play around as needed. With that said, it's not wrong to try more 🙂 but you're then just running the risk (excuse the pun!) of having tummy upset but probably not much in the way of performance benefits. Hopefully that helps, let me know if you've got any more questions! Good luck with it and have fun 😃🏃♂️

hallo, thanks for the very helpful video. i ordered an energy gel for an upcoming half marathon. i realized that on the packaging it says, it consists of 99% Honey. Now my question: can i simply mix normal honey and water in a soft flask and use this as my nutrition during the run? or will the mixture with water do some sort of changing the effect the body processes the carbs from the honey? salute ✌🏼
@NutritionTriathlon Жыл бұрын
Hi Niko 🙂 you're welcome! So yes, I can't see any particular reason why mixing it with water would be a problem. You would just need to make sure you're still consuming your target carbohydrate intake if it is diluted in water, and also just text this to make sure you tolerate it OK. Try it multiple times for runs before your half marathon and if you don't get any problems then it should be fine 👍 hope that helps

Hi James, Quick question: How come carb loading is recommended for 1-2days prior to race day to have any effect, but energy gels containing carbs are easy absorbed right away during the race? If carb loading requires more time, wouldn’t the gels also need more time? Just trying to get a better understanding, thanks!
@NutritionTriathlon 3 ай бұрын
Brilliant question! Love it. It's mostly a numbers game. You're trying to saturate glycogen stores to max capacity, which is around 2000 calories worth of carbohydrates. You can't do that in one meal and so you need to do it in multiple meals, which is then your carb load period 🙂 hope that makes sense!
@friponX Жыл бұрын
Regarding energy gels during a half marathon, is it advisable to take in the entire gel in one go? Or is it okay to consume it partially but increase the consumption frequency like half at a time?
@NutritionTriathlon Жыл бұрын
Whichever you prefer really. As long as you're consuming the same amount overall - whichever works for you best. Practice in training and see 🙂
@james08022 8 ай бұрын
I am intrigued by the different rates of carb intake based on finish time. Why would it not be the same rate of intake regardless? Thanks!
@NutritionTriathlon 8 ай бұрын
Really great question. Broadly this comes down to "need" and the risk versus benefit of taking on nutrition. The quicker you complete the race, the less likely you are to need nutrition due to a lower chance of stores running out. The longer it takes you, by nature the higher the risk that your stores will replete and negatively impact performance. So those taking longer will have higher needs. Additionally, it takes time for nutrition to be absorbed and used by your body. Again, less benefit for shorter timeframe, more for longer duration. However, it's not wrong at all to consume the same amount as for the longer distance - and there's a growing trend of elite athletes doing this. It's just got to be practised in training, at race intensities, to ensure you can tolerate it. Hope that helps 🙂

@@NutritionTriathlon hey. Thanks for your quick reply. I meant how many grams of carbs per kg in a normal training period training for an ironman with about 10-15h of training a week. Since I have seen your supersapiens videos and read the „Glucose Trick“ book and aim to get my glucose curve flat I ask myself if I should even take carbs or if I do so how many
@NutritionTriathlon 2 жыл бұрын
Gotcha! Just off the top of my head, I suspect around 3-6 g of carbs per kg of bodyweight per day would be about right for 10-15 hours of ironman training. Maybe more depending on intensity. Unless you have a specific reason not to eat them, carbs are essential for anyone training for any ironman. Don't worry about making your glucose level 'flat' either - it's normal for it to go up and down 🙂 I hope that answers your question, but let me know if it doesn't or you have more!

@@NutritionTriathlon thank you very much. Really helpful!!! After my gcm plugged and read the book I was worried how to take so many carbs in without spiking.

@NutritionTriathlon 2 жыл бұрын
Totally normal for your glucose levels to spike and then come back down! 🙂 That's just a normal bodily process. If you do keep seeing really high glucose levels though it can serve as a good prompt to consider what you're eating and the macronutrient split. So for example, are those meals lacking protein, fibre or fat? It can prompt you to just double check those sorts of things!

If you're looking to carry your own drink then you could essentially pick any of the other sports brands that are out there. Common ones like maurten, science in sport, neversecond and precision hydration all do carbohydrate based drinks with electrolytes in them. Depending which you go for, you could just add a small amount of normal table salt (about 0.8g of table salt per 500ml of fluid is a good starting point). That would also mean you could combine your carbohydrate and hydration needs. If you wanted to use gels or other food for nutrition then you could make and carry your own electrolyte drink, essentially just water/squash with normal table salt. If you're making your own then about 1g of normal table salt per 500ml of fluid should be about correct. This is quite individual and you might need more, but it's a good starting place. Hope that helps a little bit?

@NutritionTriathlon 11 ай бұрын
For the average runner? Caffeine, and that's about it. Quite honestly, there are very few supplements with any proven benefit, and the ones that do have a benefit aren't particularly helpful for endurance athletes. Focus on a healthy diet, do the basics right like balancing training load, recovering properly and getting enough sleep. Optimise protein and carbohydrate intake, and optimise meals around training. For the vast majority of runners, supplements are unnecessary.

Last week I did a 10mile run and it went pretty well. This week I was supposed to do the same distance but I couldn’t finish the last 2km. I’m still trying to figure out what works for me in terms o food. But would you say that’s mostly related to nutrition?
@NutritionTriathlon Жыл бұрын

@danielcarlossmd Жыл бұрын
I think I just didn’t have the strength to keep going. I didn’t feel hurt or exhausted, which is the confusion part. From my research I’ve learned that a single gel during the run isn’t enough for me, given I run the 10mile in 1:40h. And from my calculation, for the 21km I’ll have to take three.
@danielcarlossmd Жыл бұрын
Another strange part is that this is my second attempt to run my first half marathon. The first time I wasn’t paying attention to nutrition at all besides having a pre training meal. I managed to run 20km without taking any gel whatsoever and without carb loading (intentionally). But when I tried the 21km I had to start walking in the last kilometers because I didn’t have the strength anymore.

@@NutritionTriathlon that's an interesting question. There is definitely a line in the sand somewhere. I'm saying shorter races don't require food fueling.

Of course, if the goal is simply to complete it, then anything goes.
@NutritionTriathlon 9 ай бұрын
A 5k and a half marathon are very different. The reason why half marathon fuelling is important is because we only have enough carb stores for about 90 mins of hard, steady exercise, and that's if we have full glycogen reserves to start with (which many people don't). Fuelling stops critically low glycogen levels and can be very important for a half marathon. 5km on the other hand - yes, no need for any nutrition during it!
