News - Carl and James box clever in Bangkok

Battling to avoid a place in the final week our four remaining entrepreneurs are going halfway across the world to Bangkok to strike it rich in the sport and leisure industry.

Roughing it again in a £12 a night hostel they have to adapt to the Thai capital's mix of culture and hedonism.

Natalie and Lucy are hoping it will be third time lucky for their partnership. They find a hostel and negotiate with the owner of a spa upstairs to offer massages to travel-weary backpackers as part of a 'pamper party'.

Sports fans James and Carl opt to try and cash in on the popularity of Muay Thai boxing. They successfully sell their idea to a couple of ex-pat tour operators for a website selling tickets to tourists, earning a commission from the stadium.

Next in the guys' sights is a luxury spa with no hotel contacts. Working through the night on another flashy business plan, they find 39 potential partner hotels in just a day and the baht come rolling in.

After a long hot slog the entrepreneurs meet to reveal the winners. Counting in all their costs Natalie and Lucy have made just 5971 baht, less than they started with. James and Carl are this week's clear winners, their two inspired ideas netting 35,380 baht.

The guys use their combined pot of winnings for one final blow-out in Bangkok before flying home.

This marks the end of Natalie and Lucy's alliance as next week they'll be going head-to-head in Hong Kong.
