As much as I love running I cant listen to any of the strained, contrived and inane podcasts about the subject but that is different thread.
Usually the same, but recently started listening to the British Ultra Running Podcast by James Elson and Dan Lawson, both quite handy runners (and James is the RD for the Centurion events). Recent episode about the Arc of Attrition was interesting (was down there volunteering on that, great event despite getting stuck in the snow trying to get there), and another interesting episode is the one where they interviewed Jon Steele, RD of the Hardmoors series. They spent quite a bit of time talking about the Hardmoors 55 last year that got a lot of bad press after the papers (and later Radio 2, gotta love Jeremy Vine) misreported that runners were rescued by Mountain Rescue, despite Mountain Rescue themselves praising both the organisers and the runners for being well equipped, well prepared and experienced for the conditions, and MR had simply offered to assist with transporting runners back to race HQ.
