Just completed 25mins non stop and in the rain. Not very fast yet during the run but did manage to up the pace as Laura suggested for the last minute. A good app to use as well is the Nike+gps. It costs a £1.49 but it well spent I think because it tracks where you run and the distance and speed. When I graduate I'll be using this all the while as there is loads more that it will as well. To everyone who is doing this, keep going as it does get easier as your fitness level increases.
