Day 5 - done!
I ran exactly 18.5km in exactly 90:00. This was off my anticipated pace, but I don't think it is because of a lack of fitness. I met some old friends last night and had a bit too much beer.
Incidentally, I could have picked up the pace a bit but am not sure how hard I should push the long run. Today was basically zero effort, although my legs were a bit tired the last 2km or so. How much effort should I be putting into these long runs?
