Carb Loading When & How

I don't know about super-long walks, but from Marathons general opinion is you can't store that much extra by doing traditional carb-loading, i.e. going low carb for a couple of days of hard training then stuffing yourself with pasta.

You should store as much as you need by tapering, so if you've been training for long distances, cut down dramatically over the last week or so and rest entirely two days before your challenge, eating as much as you normally do. Keep it balanced, so don't shy away from protein and fat too. I'm keen on a big spaghetti bolognese the night before an endurance event!

Have a good breakfast (I recommend double porridge) and given the time you'll be out there, bring lots of easy to digest on-the-go food. Energy bars and the like are good, but you may find you get sick of sweet stuff. I take pretzels on long runs for a salty carb hit.

Good luck!

honestly you can do it the night before.

I`ve been advised to eat at least 10 times my bodyweight in Kilos for the 3 weeks before the challenge...Thats a staggering 800-900 gramms of carbs a day...Thats ten time what i normally eat in a week !

you're body can only store so much water and glycogen. That is limited by how much muscle you have. Only reason I could think of why you would need to eat that many carbs would be to put on body fat, but you're doing a walk, not swimming the english channel.
