This girl is on fire!
Some people are content to eat cake on their birthdays, but Pippa Middleton decided to celebrate the day after turning 32 by participating in an arduous 75-kilometer (almost 47 miles) race on Monday.

You could say she truly labored on Labor Day! HA!
The Otillo Swimrun World Championship takes place every year in Sweden, and consists of six miles of swimming in the Baltic Sea and 40 miles of running.
Pippa and her brother James Middleton completed the course in 13 hours and 4 minutes along with their teammates James Matthews and Jons Bartholdson!
The socialite and her team competed for the Michael Matthews Foundation, which builds schools in needy areas throughout the world.
This wasn't her first time at the rodeo, though!
Pips completed a 54-mile bicycle race from London to Brighton earlier this summer, and participated in the Bosphorus Cross Continental Swimming Race in Turkey.
We are in awe!
