Finally got hold of a pedometer. It only marks miles, so now I know I ran for 25 minutes and went 2.1 miles. By my calculations that is not very good - only a bit faster than a brisk 4 miles an hour walk. You guys who have graduated, did you get faster automatically or do you have to push the pace eventually? However, 3 months ago I couldn't run for 5 minutes, let alone 25 so this does work!
