Olympic and world champion Michael Johnson chats to Brendan Foster as he organises the 30th staging of the Great North Run.
In this BBC ONE documentary, Michael feels the buzz as veterans, fun runners and fundraisers talk of the pain and pleasure of taking part.
One of the greatest long distance runners of all time, Haile Gebrselassie, tells him of his pride at taking part this year for the first time; and Michael shares the intimate and sometimes heart-rending stories of those who have benefited from the millions the run raises for charity.
