Gels are brilliant when used properly but can cause severe stomach cramps if you can't process them. So make sure you DO try a gel at some point during a long hard run, long slow runs won't replicate race pace feeling.Possibly of more importance then gels (and sugars) can be electrolytes which keep the dreaded cramp at bay.

Maybe the sweet spot is the marathon distance. Any shorter and you definitely don't need it. Any longer and you probably can't take in enough to make much difference.

nerraw1111 wrote: » Question is whether you need them or not. In contrast to Enduro, other top guys in ultra running rely on gels, such as arguably the best ultra (trail) runner in the world at the moment, Killian Jornet. He also eats jam and nutella but try sticking them down your shorts. http://www.irunfar.com/2011/10/race-nutrition-with-kilian-jornet.html That said, he doesn't take anything during (short for him) 6 hour runs. Like anything in this sport, it depends on the individual.

Sure, it's definitely adding fuel to the tank, and I do it occasionally myself in races in extreme circumstances. But there are much better (and nicer) ways of fueling up (in general). I definitely don't agree that the aproximate distance from Marathon to Athens, plus a few hundred extra yards for the king to see the finish line, is likely to be a sweetspot for thousands of millions of human evolution. Why would it be? There is nothing special about the marathon distance. It's just another completely arbritary distance.
How many gels do you reckon John Tracey consumed when he set the Irish marathon record? (or used in training for that matter).

You can run slower if you want and burn more fat, but ideally you want to just about run out of glycogen on the finish line. Also, the more glycogen you burn relative to fat, the faster you can go.

Don't they put their own drinks out on the course in advance? Reminds me, I've a vague memory of Jerry Kiernan talking about it. I think he said both himself and Treacy only used water, and there was something about the '84 Olympic marathon, and some shenanigans with runners stealing each others drinks. Kiernan accused Treacy of stealing his, because someone had taken Treacy's and he knew Kiernan's was just water :pac:

It definitely doesn't fit in with my own personal experience (and whilst one person conforming to the theory doesn't really show anything, one person definitively not conforming to the theory shows that at the very least its not absolutely correct).

I doubt that the upper limit is signficantly higher than 26 miles in anyone. But, maybe for the likes of John Treacy it was higher, and knowing that it made sense to just take in water. That's why I think it's a different story for ultras where fat burning has to have a bigger influence.
There are much better sources to draw on, including your own in-built fuel tank (fat) if you train your system appropriately.

My farthest training run was 34km(no gels etc.) and felt relatively ok during it but how do know when your body is fat burning as opposed to burning carbs. i have taken gels during marathon but only took because a lot of other people were rather than feeling i needed them.
