M&S reckon brains are quite important, so they took some advice from the British Nutrition Foundation and made their new brain food range, which makes it easier to get vitamins and minerals our noggins need.

So if you're a person with a brain, you might want to give their new brain ball a try.

It's made of delicious dates and berries, filled with almond butter and packed with nutrients like iron and zinc, which help to keep your brain running smoothly.

This is not just food. This is M&S brain food.

This is a global player original podcast.

So this is a bit of a special episode for Big Fish, a bonus episode of sorts.

We're going to be talking about the Jungle Ultra with my friend and Vogue's close friend and trainer, John Belton,

with whom I flew to Peru to undertake this, what do you call it,

ghastly challenge of mental resilience and physicality?

I'd probably call it something different now than I did at the start before it even happened.

But yeah, ghastly is definitely one of the words I'd use.

Gasly's a good word.

An epic five-day stage race through the Amazon jungle.

So for those of you that did not follow the race,

it is a 230-kilometer self-sufficient foot race

through the Amazon jungle.

Starting at altitude, up about five hours from Kusko, an ending down in the Amazon basin.

And self-sufficient means that you have to carry all of your equipment, you have to ration all of your food for the five stages.

If you eat too much, you will have no food. There is not extra food. If you eat too little,

you will have extra food to carry. And if you eat too much, then you will have no food. And

there is no way of topping up. You will be pulled from the race if you misjudge that.

You also carry your hammock and the trusty hammock, I can't wait to talk about the hammock.
