Tempting Fortune

Twelve Brits land in South Africa to begin a gruelling 18-day trek. Will they spend any of their prize pot along the way? When a single shower costs £1000, the bill can rack up quickly...

Alliances are starting to form, and as bodies ache and morale drops, the temptations are becoming harder to resist.

A vast ideological split has formed between the trekkers. Will any of them trade a chunk of the prize money for an evening in a living room that's just like home?

Fatigue is setting in and the mood in the group is at an all-time low. They could do with a pick-me-up - just like a lavish party that's plonked right in their path...

The prize fund has taken some hits and the trekkers are divided. But will that stop anyone from spending more of it on a trip to a cocktail bar?

The trekkers enter the final stretch of their journey, and the prize money is tantalisingly close. But a bombshell rule change throws everything up in the air.
