This week I will attempt to climb the three highest mountains in Scotland, England and Wales within 24 hours. This will involve many a blister, creaky knees, very little sleep, and possibly (definitely) a few tears. It may also involve mountain lions, wildlings and flare guns. You never know.

It's all for a great charity, Crisis.

For those of you who aren't familiar with the work that they do, Crisis is the National Charity for single homeless people. They are dedicated to ending homelessness by delivering life-changing services and campaigning for change.

So please, dig deep and donate!

Much love, Giulia.
