TWO events are in the triathlon calendar at a top garden.

Stourhead is hosting an Immortal Triathlon on Saturday (May 14) and Sunday (May 15).

More than 500 triathletes will be heading to the estate for either a sprint distance or middle distance event.

The event, which is in its third year, has been organised by Immortal Sport.

"The event at Stourhead is a real highlight of the year for us at Immortal Sport," said race director Steve Elliot.

"It is such a beautiful location, and it is great to work with the National Trust to host an event with such a 'wow factor' for the athletes from start to finish."

Registration is open until midnight on Wednesday.
