A triathlon started by Olympic stars Alistair and Jonny Brownlee is coming to Harewood this summer.

The medal-winning brothers, from Bramhope, successfully launched their Brownlee Tri series last year.

Now the Brownlees have teamed up with Macmillan Cancer Support to get behind what will now be called the Macmillan Brownlee Tri in West Sussex, on June 15, and at Harewood House on Sunday, September 21.

As part of the partnership the charity will have more than 300 competitors raising money, while triathletes Jonny and Alistair are due to appear on each day.

Designed to appeal to a range of abilities and ages, both events will include sprint and super-sprint competitions for youths and adults, along with a sprint relay.

In a joint statement the Brownlees said: “We’re delighted that such a fantastic charity has chosen to partner with the Brownlee Tri. Triathlon is a great way to get active and competing for Macmillan Cancer Support provides the perfect motivation.

"Petworth House and Harewood House are two brilliant locations for a triathlon and we hope as many people as possible will join us."

Triathlon team manager at Macmillan, Hayley Short, added: “We are thrilled to be the new title partner for the Brownlee Tri Series.”

Competitors will receive free training plans, goodie bags and prizes and a triathlon insurance discount - for more details visit macmillanbrownleetri.com.

Alistair Brownlee won the gold medal in the triathlon at the London 2012 Olympics, while Jonny took the bronze.
