With just a day to go before the opening ceremony of the London Olympics, all eyes were on Kate Middleton as well as Princes William and Harry as they took part in sports day at Bacon's College, a secondary school in East London.

The trio visited the school to launch a program called Coach Core -- an initiative aimed at training talented young athletes (ages 16 to 19) in London's most impoverished neighbourhoods to become coaches.

While Harry took to the basketball court and William played some football with students on the soccer pitch, the focus was, of course, on Kate as she played table tennis in a chic, fitted grey and white A-line dress from British design store Hobbs. The Duchess paired the frock, which reportedly cost £35 (or approximately $60), with a perfectly placed white belt, low beige wedges and her stunning blue engagement ring from Will.

The event is a kick-off to the Royal family's hectic Olympic schedule. Starting tomorrow with the Olympic opening ceremony, Kate, Will and Harry will attend nearly every summer games' event, including field hockey, soccer, basketball and beach volleyball.

Which means, lucky us, we're sure to see many more regal spottings over the next couple weeks.

Check out some of the images from the event.
