Nothing can stop Pippa Middleton! The 31-year-old English socialite was the epitome of #FitnessGoals over the weekend when she completed the Safaricom Marathon in Kenya, Africa, People confirmed. The 26.2 mile journey wasn’t your average walk in the park though, as Middleton was tasked with handling the scorching East African heat and exhausting high-altitude air at more than 5,000 feet. And just last week, the beautiful brunette traded her trainers for a bicycle when she teamed up with brother James Middleton for a 54-mile bike ride from London to Brighton to benefit the British Heart Foundation.
