The Duchess of Cambridge sports a tracksuit for Wimbledon tennis event

The Duchess of Cambridge showed her sporty side once again at a tennis engagement on Wednesday (Jan. 17), trading a chic red coat for an athletic tracksuit on her second outing of the day. The 36-year-old was on hand to see the work of the Wimbledon Junior Tennis Initiative at Bond Primary School in Mitcham.

A patron of the All England Lawn Tennis and Croquet Club, Kate paired a white Clarice track jacket, which retails for $222, with black leggings that featured a white stripes down the side and a pair of Nike sneakers.

Kate also wore her engagement ring during the tennis visit, which she had previously taken off during her earlier visit at Great Ormond Street Hospital. The mother-of-two had visited the hospital wearing a chic red coat from Boden, priced at $377, which she teamed with nude tights, a simple black clutch bag and Annoushka Baroque Pearl Drops earrings - which she kept on during the tennis trip.

A keen tennis player herself, Kate got stuck in during a tennis training session with a group of school children. The Duchess showcased her talents as she caught the tennis balls that were being thrown her way. Before leaving, Kate was gifted with some tennis rackets for her two children, Prince George, four, and Princess Charlotte, two. Charlotte in particular will no doubt be thrilled to receive the present, having recently started tennis lessons herself at London's exclusive Hurlingham Club.

The Duchess of Cambridge recently revealed that George is also learning how to play, but at his age, admitted he just "wants to whack a ball". Kate opened up about her son during a visit to the Lawn Tennis Association in October, where she took part in drills with children and spoke to tennis coaches and players including Johanna Konta, Britain's No.1 tennis player. Kate asked LTA coach Sam Richardson for advice. He later revealed: "She says with George just being four he wants to whack a ball, so she was asking what sort of stuff should she be doing. They will struggle at that age to hit a ball. She said he's interested in it, but more in whacking the ball."
