Spencer Matthews has been on quite the life journey. When the public first encountered the Eton-educated cheeky chappy, he was a notorious bad boy on the 2011 season of E4’s scripted reality show Made in Chelsea. But by 2018, Matthews had embraced stability via marriage to Irish model Vogue Williams. Then came another recent swerve: Matthews’ endurance athlete era.

In 2024, his Great Desert Challenge saw him complete 30 marathons in 30 days, breaking a world record. At the tail end of 2025, he completed seven Ironmans on seven continents for Project Se7en, raising funds for UK charity James’ Place.
