Football fans have come from all over the world to watch the World Cup matches, but not many can say they travelled across South America on foot.

Four England fans walked for 100 days from Argentina to Brazil to raise money to build a water well in the host country, which has been suffering from drought.

Adam Burns says they walked a total of 1,966km (1,121 miles) , a reference to the year the last time England won the World Cup.

For the BBC's Real Fans series he told Franz Strasser that along the way they faced extreme heat, were charged at by bulls, and picked up what they thought was a stray dog.
