Yay! Week 5 completed by myself and my canine companion Jet.
Run 1 went fine.
Run 2, two lots of 8 minutes was not great. It was a warm evening. The first minute of the first run was agony on the knees for some reason (I've had this before- not sure why) but I kept going and the knees became OK. The last 30 seconds of the second run was really hard, I nearly stopped. My canine companion took the cool down walk as an opportunity to go and jump in the local lake. I arrived home, red in the face and melting with my canine companion dripping and covered in duckweed. Unfortunately we had a visitor - my other half's boss, who immediately shook my sweaty hand.
Strangely run 3 went fine.
