I decided it was too slippery and treacherous to do Run 3 outside today so I did it on the trusty treadmill. It was another good session. I've really enjoyed this week and have really felt like I've made some progress.
Feeling ever so slightly nervous about Run 3 next week... But I will do the build up to it and see how I go. With it being Easter and having a few days off work, I might jig things around a bit so I can repeat Run 3 if I feel the need.
