Even her tracksuit bottoms are posh! Kate works up a sweat in a pair of £220 designer joggers while taking part in tennis workshop with Judy Murray in Edinburgh

The Duchess of Cambridge was spotted laughing raucously with Judy Murray today as she carried out a number of engagements in Edinburgh, pictured right. Kate, 34, visited Craigmount High School, in the west of the city, where Andy Murray's mother hosted a Tennis on the Road coaching clinic, left. Judy founded the project in 2014 with the idea of increasing coaching capacity and growing the game at a grassroots level. The Duchess looked her usual stylish self in a recycled a dark green Max Mara coat she had previously worn on Christmas Day while attending church in Sandringham.
