Pippa Middleton Takes Her Famous Butt For A Run

Run, Pippa! Run!

One of the world’s most famous British behinds was accented by a pair of tiny jogging shorts on Thursday when Pippa Middleton went for a run near her London.

Demonstrating perfect form, the Duchess of Cambridge‘s sister looked like no stranger to pavement as she got some quality cardio in for the day.

Wonder how far she ran? Last we heard, Pippa finished a 50-mile duathlon across Scotland! What ridiculous feat of physical endurance is she training for now?
