Prince Harry hopped on a treadmill inside a test chamber during a visit to the BAFTA headquarters in London today. He was participating in the launch of Walking With the Wounded's Everest 2012 Expedition. Harry was involved with the organization's North Pole attempt last year and was named a patron of its latest adventure this afternoon. It's been a busy day for the prince, after he also made an appearance at the Royal Air Force's Honington base to meet with servicemen and women this morning. Harry will return to the line of duty himself later this year when he'll serve as an Apache pilot in Afghanistan. Until then, it looks like Harry is enjoying juggling work and fun since he hit the town with pal David Beckham last week.
