Also worth mentioning, is that my Garmin may be recording my cadence as my heartrate, I hope this is the case, it has been discussed in the Garmin thread. It may mean my max heartrate is not what I thought it was (I always thought a max heartrate of 186 for a 58 year seemed high!), it is something called 'cadence lock'. Just fyi for you garmin users

Maurten sounds quite interesting, though only theoretically for me because my stomach copes fine with ordinary gels and sweets (and probably wouldn't mind if I munched sausage rolls and iced sponge cake while running) and the only barrier to me fuelling during long runs is my near-total inability to do more than one thing at a time, including running + eating.

I do pretty much all of my training without food/water unless I know it will be hot and even then, I'm not always that kind to myself! I figure that come race day, my body will be pleased to see any water/gel...

I'm with OTG on not drinking or eating on training runs, though I normally allow myself one marathon paced run with some fuel just to practice.
I can't imagine swilling half a litre of energy drink on one go and then carrying on running!
On the basis that in theory we can all absorb 60-90g of carbs per hour, I do a gel every 25 minutes or so (that's about 22g, so on average closer to 50g per hour). And make sure I get them down early. There's no point waiting until later when your guts in a mess anyway due to fatigue (is my rationale, anyway!) and as someone once said a gel in your stomach is still outside of your body, so I'd rather get carbs into my bloodstream at the start, after 3 miles, 6 miles, 9 miles etc and then if I get nauseous at 15 or 18 miles I know I've already taken on board a load of usable carbs that should see me through to the end.
I asked on the 3:15 thread what people thought about energy drinks in marathons and the general view there was that they are ok for either a) placebo / mouth swill effect or b) drip feeding a few more carbs slowly, but never a whole bottle quickly.
Maurten is intriguing but I'd need a new mortage to afford them!

Exactly this.

I'm fine with fuelling, especially on easy runs. The only issue I have with the longest runs (including the marathon itself) is that I can't take too much sweet stuff. The solution is to have some savoury snacks early and keep the sugar until later.
When I did the virtual London marathon in 2020 I did 10km loops to my house and had a right stash of food. Mini-pork pies...😋
As for *not* taking anything, if I'm running a lot then I get to the point that I can do a two hour run in the morning with nothing except a drink of water before I set off. However I've found I can't if it is later in the day, I have really run out of energy on a post work long run when I've not taken anything. Not entirely sure why.

My first marathon which is also my PB I took nothing apart from water at the stations. Nowadays I take a few shot bloks. On my couple of ultras I took a picnic🤪

No matter how much one would think not fueling or drinking is an other accomplishment besides running 42195m.
If one would like to do it as pleasant and fast as possible, fueling and drinking will make it better. It’s just physics. But it also needs training to get use to it and find out what will work.

I don't think there is any doubt that fuelling is beneficial during a raced marathon where you're looking to achieve the best outcome possible. My only query would be whether the same is needed in training, especially if sticking to the "usual" approach of running long runs at an "easy" pace.
For race day, we all need to find out what works for us as individuals, and in the usual "normal distribution" of physiology, most of us will need the same sort of thing - carbs, regularly, before gastric distress. Some may be able to avoid carbs through their own unique physiology or adaptation through training, and some may find that their bodies respond to carbs in a different way so can only take them on later, or will have unavoidable gastric distress.
The difficulty with training and fuelling is that you are rarely putting yourself in a race simulation position where the fuel you are putting in and the effort you are putting out are in any way comparable with marathon race day so marathons, especially the first, will be a journey into the unknown; so there is mileage in testing out fuelling in slower runs or shorter runs as that may be the best that can be achieved, but it will also be different on race day!
