Pippa Middleton is on the move! The beautiful Brit completed the Safaricom Marathon this week in Kenya, Africa, and needless to say, we're impressed. Not only did the royal-in-law run 26.2 miles in the blazing heat, but she did it in high-altitude air at more than 5,000 feet. Kate Middleton's sister ran the marathon to raise funds for the charity Tusk Trust, of which her brother-in-law Prince William is a patron.

But this isn't the only thing Pippa added to her athletic résumé this month—last week she teamed up with her brother James Middleton for a 54-mile charity bike ride from London to Brighton that benefited the British Heart Foundation. Talk about #fitspo.
