Pippa Middleton's Brother-in-Law Spencer Matthews Goes Shirtless at the Beach Ahead of Crazy New Marathon Goal

Spencer Matthews is putting his fit figure on display!

The 35-year-old British reality star, who happens to be Pippa Middleton‘s brother-in-law, was spotted at the beach with his wife Vogue Williams on Monday (July 15) in Marbella, Spain.

Spencer is the younger brother of Pippa‘s husband James Matthews. He has been seen on shows like Made in Chelsea, Celebrity MasterChef, and The Jump.

Spencer is getting ready to attempt a world record by 30 marathons in 30 days, all on the sand in the desert.

“I love adventure and taking risks, and I knew that I wanted to run a marathon every day. Thirty days was the most I could get away with, with work and Vogue and the kids, but I wanted to pick somewhere really hot, as I loved the Marathon de Sables, so I just cooked up the idea and combined the two things,” Spencer told T3.
