This is it!
“I could not be happier to take part in the Gibraltar Rock Run with my brother and his fellow Royal Marines especially during such a momentous occasion. I will remember this day fondly."
The run is just one of the many events planned for this weekend in Gibraltar, as the UK celebrates the 350th anniversary of the formation of The Royal Marines. We will be there to bring you updates and we'll also be talking to Henry!
So if you have any questions about his participation in the run, or his work with The Royal Marines Charitable Trust Fund, please leave them in the comments section.
And don't forget to keep cheering Henry on with your donations and messages on his official fundraising page. Help him reach his target! - Gibraltar, here we come.
