Whoop whoop - only 9 minutes to some people but compared to where I started it's a bloody miracle I can do this!
No problems with the run itself but my left foot is now slightly swollen with some mild pain. I think I will rest over the weekend and complete run 3 on Monday evening after purchasing some proper shoes rather than continuing to run in pumps.
Thanks everyone for the support so far. You're all really helping to give me that motivation I need.
