In my 60th year, Natalie and I are starting the celebrations in style by taking on the formidable Royal Marines 'Bottom Field' and 'Endurance Course' in a back-to-back challenge. We are raising funds for a fab cause, close to our hearts, the Royal Marines Charity. The elite PTI team at Commando Training Centre Royal Marines will push us through the hardest military training challenge, so we can experience a small part of what it takes to be part of the World's finest military force.
