On this week's show Martin speak to the co-founder of Strava Mark Gainey about segments, set up, the Rim to Rim and the future. We remember American track star Gabriele Grunewald, young Brit track stars re-write the record books, Kara Goucher runs Leadville, Kenyan marathoner banned for rat poison. We talk summer speed work to sharpen you up, you rate your run, talk about what keeps you going, wear your MT kit at Comrades and stand on the MT podium.
