Pippa Middleton scales Matterhorn in honour of fiancé’s brother

Speaking about the impressive climb, the party planner revealed that she chose to take on the challenge in memory of her fiancé James Matthew's brother, Michael Matthews, who died climbing Everest in 1999.

Matthews was just 22 when he summitted Everest and the youngest Brit ever to have scaled the peak at the time.

The extreme sports fan made the 4478-metre climb in Swizerland with her brother James Middleton over the last few days.

They spent 15 minutes at the top before starting their equally treacherous descent.

The climb was not just a feat of human nature, it was also to raise money for the Michael Matthews Foundation which builds schools in remote areas.

"It was humbling to have been able to climb one of the world's most beautiful mountains and raise money for a charity created in memory of an extraordinary young man who lost his life on another peak” said Pippa of the achievement.

Despite her husband-to-be also being very active, he chose not to join Pippa on her adventure due to emotional reasons.

Pippa is known for her impressive fitness, having completed the brutal Great Wall Marathon in northern China, finishing 13th overall in the women's race.

She also conquered a 4,800-kilometre charity cycle ride across America with brother James in 2014.
