There's no stopping Pippa Middleton!
The 32-year-old sister of the Duchess of Cambridge completed a nearly 50-mile swim-run race in Stockholm, Sweden on Monday, Sept. 8, with a smile on her face!
A day after her birthday, Kate Middleton's younger sister partook in ÖTILLÖ, which is a race where teams of two swim between 26 islands and run over them. In total, Pippa swam 6.2 miles and ran 40.4 miles. Talk about impressive!
