Garry Doolan is the sort of ultra runner who runs the really crazy stuff - recently he started The Line - a Mark Cockbain event starting in the north of England and travelling approximately 330 miles down the Meridian Line of the UK to Brighton. He chats to Kate and Robin about Mark's events, plus others such as Huw William's Pen Llyn Ultras, GB Ultras, NAV4 and all the variables you can get in events in the ultra world. They also discuss the demons suffered when something goes wrong and you have to DNF.
