W8R1 and ran 28 minutes for the first time! Deliberately slowed down at several points (thanks all for the tips about this) so that I had enough energy to get to the end. Still can't really believe I am doing this, and neither can my family!
Anyway, just about halfway through the cool down walk I suddenly found myself face to face with four large cows who were blocking the exit to the field. Had to quickly back track, stagger up a hill to the top path, climb over a gate and take the long way home! Now giving myself a long rest...
