Kate Hudson wants to compete in a triathlon.

The 'Fool's Gold' star has revealed she loves being physically active and is keen to test her competitive streak by taking part in the three-sport event.

She said: "Sports are big in my life. I swim, run, bike and dance, play volleyball and soccer, and I want to start training for a triathlon. I'm one of those people who love to be active."

The 29-year-old blonde beauty said her love of sport helped her lose 50lbs after her son Ryder — her child with ex-husband Christ Robinson — was born four years ago.

Instead of working out in a gym, Kate decided to have fun while she lost weight, playing the sports she enjoyed.

She said: "Life is too short to be concerned with anything but having a great time."
