Pippa Middleton competed in a 5K in Britain Saturday, and everybody's favorite Maid of Honor looked like she had not even broken a sweat at the finish line!
Pippa's race was part of the GE Blenheim Triathlon which takes place every year on the grounds of Blenheim Palace.
Kate's sister ran with two male friends, and finished the 5K course in 25 mins., 30 secs.
"People were excited to see her," said Alex Coulson, one of the event's organizers.
