Eliud Kipchoge's attempt to break the 2-hour marathon barrier was either a commendable attempt to test the outer limits of human endurance... or a deeply cynical marketing ploy to convince you to buy some runners. David Epstein, author of "The Sports Gene" is better placed than most to separate corporate speak from genuine athletic curiosity, and as Kipchoge's attempt fell 25 seconds short, there's the question of just how fast a marathon can be run by a human being. The GAA championships got underway for another summer this weekend, and Sligo were put to the pin of their collar to beat New York in the Bronx last night. Charlie Harrison, their veteran all-star full-back joins us to tell us why they felt the world was against them in the run-up. Plus there's Richie Sadlier's attempt at racing immortality, Tyson Fury's answering machine, and another chance to hear Lance Armstrong telling us what he's on.
