The Duchess of Cambridge’s sister swept her brown hair back into a ponytail and kept her jewellery to a minimum.

Since giving birth to baby Arthur eight months ago, Pippa has regularly been spotted pushing her son in his pram along the affluent London streets.

Last week she was seen pounding the pavements of the Chelsea Embankment as she went for a run with her little boy in a jogging stroller.

Pippa showed off her toned physique in a navy blue fitted vest top with a pink lining and let her long dark hair flow behind her as she ran.

Running with a buggy is a good way for new mums to return to fitness, though it’s generally recommended that babies should be around six to nine months of age so that they are able to sit up and hold their head properly. 

The Middleton sisters are both gifted sportswomen, with Pippa’s sister Kate taking part in a charity sailing regatta last week.

She and the Duke of Cambridge hosted the inaugural King’s Cup to raise awareness and funds for eight of Their Royal Highnesses’ patronages.

The event saw the royal couple go head to head as skippers of individual sailing boats, in an eight boat regatta. 

Prince William and Kate finished in third and eighth place respectively but put on a sportsman like display at the prize-giving ceremony, congratulating winning skipper Bear Grylls as he was presented with the trophy.

The Duchess of Cambridge was then handed a large wooden spoon after finishing in last place in the race.
