Henry just kicked off the Commando Challenge weekend, with a glimpse at a mystery shoot in London involving The Royal Marines.
We can't wait to find out what that's all about!
In the meantime stay tuned for updates from Devon, where Henry will be taking part in the Commando Challenge tomorrow. We'll be talking to him, and hopefully bringing you live coverage from Woodbury Common.
And don't forget you can still contribute to his fundraising page. ONE DAY TO GO!
