Notes
Finally did it - 20mins @16kmh. Not expected - I thought 10mins or 3km would be my limit - and not as hard as I expected either, though it was very difficult for the last 4min. The rest of the time felt fast but I wasn't tiring much. When I looked at the clock it was 16mins, so I thought a big effort to get to 5km was on. Then it's just over 1min to get the full 20mins done. Supershoes help, and I have done a couple of maximum efforts in the last 2 weeks. Plus weight is around 75kg. Once I got to 10mins I felt anything more was a bonus and wanted to get to 15mins, but when I checked it was 16mins and not far to go- better than starting again another time anyway.
