Strange test. Just went by laps not measured distance
First lap was about 8 min
Second a bit faster but around the same
4 laps in 32 min
6 in just 55 min
then 9 in 1:10
each lap I stopped to ( try) to calculate distance speed etc no longer than 30 sec rest
All weird but it was a hard effort
Time change and only 5:30 sleep (dog) but 65 HRV so I felt decent
163.6
