Low Carb Lifestyle and Running

You should watch the film Run on Fat. This is the first 6 minutes. The full film is available on dietdoctor.com
Run on Fat

Endurance runners can be fat adapted using ketogenesis rather than using glycogens. It does take some time to get used to this.

Try reading up on Prof Tim Noakes and his more recent work on Low Carb performance athletes.
A low carb skeptic friend of mine who is also a distance runner suddenly became more interested in LCHF when I told him that the great Tim Noakes was an advocate.

No, I've run 5k and 10k a few times with virtually no carbs in my diet. It was fine. Actually, I was never able to run 10k until I went low carb.

Any carbs you have in your body from an 'eatwell' style plate will last you between 18-20 MILES

Hi @Sam5350 , I lowish carb (50-80g per day) and exercise on it with no problem. Not that I've ever done a marathon, but if ever I do (!) I hope to not hit the dreaded 'wall' they talk about because I'm already running on fat rather than carbs, so with luck my body doesn't need to go through that conversion stage during the (as yet hypothetical) marathon.

And nice one for going for it! I only started exercising regularly a couple of years ago, and wish I'd started sooner! I'm trimmer now and have more stamina. Parkrun is my new favourite thing - and I'm running my first 10k race a week on Sunday! Slowly mind, but still, I'll get round!

Have had to cut back my running training AGAIN thanks to a screwy foot, but am cycling and swimming a good deal in the meantime. I am not running on Tarmac until the race itself - I don't mind temporarily wrecking my foot as a result of the race, but I'll be well cheesed off if I aggravate the problem again BEFOREHAND and scupper my chances of that medal! And my body seems to thrive on eggs, Peperami and pork scratchings..... no pasta party for ME!

Go for it!
