As the next stage of my midlife crisis, I’m taking part in a four day ultra across the frigid wastes of Mongolia. Four days of running, 25 miles a day wearing ice spikes, across the 100-mile frozen Lake Khovsgol on the Russian border. Sleeping in tents on the lake at night.

It's cold. Very very cold. Down to minus 40C.

I'm doing it for charity - to raise money for underprivileged children, to help feed, house and educate them - and give them the time and space to have fun, and just to be kids.

So please dig deep for the Jack Price Project (feeding and teaching underprivileged kids in Bali).
