Celebrity Race Across the World Premieres at 8 p.m. on BBC One and iPlayer

Overview

• Four duos take part: Anita Rani with her father Bal, Dylan Llewellyn with his mother Jackie, Tyler West with partner Molly Rainford, and Roman Kemp with his sister Harley Moon Kemp.
• The route runs 5,900km from Isla Mujeres, off Mexico’s east coast, to the remote Península de La Guajira in Colombia, with progress revealed checkpoint by checkpoint.
• The celebrity edition is a condensed four-episode series on BBC One and BBC iPlayer.
• Camera operators travel with each team but remain detached and offer no hints or directional help, as described by contestant Harley Moon Kemp.
• Producers say they intervene only to stop actions deemed “stupidly dangerous,” and multi-skilled agents accompany teams to provide security and medical support.
