One documentary that you really must see is Breaking 2. The scientific team from Nike go in search of runners that can complete a marathon in under two hours.
They don’t only want to see the fastest runner in the world but also people who could run faster. After the tests, three runners are selected that could break the marathon target of two hours: Eliud Kipchoge from Kenya, Lelisa Desisa from Ethiopia and Zersenay Tadese from Eritrea. The athletes are brought together to find out the quickest way to complete 42.2 kilometres.
