Had to get up at daft o'clock to do this, took a different route (for safety) and concentrated on Laura telling me to go easy, not get too tired , or over confident.
Oddly my breathing was easier, and at one point I didn't feel as if I was really moving much, but the buildings passed by so I guess I was!. Then she was telling me I had 60 seconds to go, so I gave her 90.
Checking the stats on return and the whole run kept under 160bpm, but averaged at 8.7 kmph. I feel so pleased, I think I can do this.
13 hour shift ahead now. Good luck to everyone today.
