Kate meets London Marathon participants at Kensington Palace

The Duchess of Cambridge played host to London Marathon participants at a special reception at Kensington Palace on Wednesday (Apr. 19). Kate, who will be cheering on runnersfrom the sidelines on race day, spoke to the athletes about the different reasons they are competing in the 26-mile run. She wished them luck with their final preparations before the team took part in a training session with coach Nick Anderson.

The mother of two dressed down for the occasion, stepping out in skinny jeans and a white, red and black striped jumper.

Her dark, glossy hair was styled effortlessly in loose curls that tumbled onto her shoulders, and as for makeup, she opted for a simple smoky eye created with dark brown liner, eye shadow in a similar hue and lashings of mascara. A subtle sweep of coral blush balanced her beauty look, while a defined brow pulled everything together nicely.
