O’Briain to tackle Zambezi River for Comic Relief

A team of stars including Irish comic Dara O’Briain will brave crocodiles, hippos and huge rapids by tackling more than 100km (more than 60 miles) of the Zambezi River.

The group – which also includes actress Chelsee Healey, Radio 1’s Greg James, Jack Dee, ex-Spice Girl Mel C and triple jumper Phillips Idowu – will be pushed to the limit as they take on the back-breaking journey in dugout boats, canoes and white water rafts for Comic Relief.
