The first 1000m was ok with heart, but legs were slightly stiff (i did warm up for 6min before)
Second 1000m was the best, felt loose, felt 70-75% of max effort.
Third 1000m was similar t second, maybe just under 80%
Fourth 1000m getting tired, around 85%
Last 1000m ok, i guess because mentaly knew that is a last one!
Rest as i said was long for me, i would say nearly fooly recovered. I would say after first 20s of rest my breathing was getting to normal.
I think that's it!
p.s. sorry for mistakes, my spelling doesn't work!
