Henry is repeating his fantastic effort last year and taking part in this fundraising event for the charity Money for Madagascar.

MfM supports orphaned and vulnerable children in one of the poorest countries on earth. They give children who have been orphaned, abandoned, abused or homeless a shelter, food, healthcare, education, water, sanitation and loving care.

Their forest and livelihood projects also enable families to sustainably support themselves, whilst protecting and restoring Madagascar's unique forests.

The cross-bay walk is around eight to ten miles and can be pretty arduous wading through rivers, tough under foot and dealing with sun, wind or rain driving across the bay.
