And this is the anecdote of the day :
Today, running was on the evening program, but I was in a very bad form, not because of something physical, but because of some anger about a chat just before running... I decided on an extreme short loop some 2.5 km... I mesured time on only part of that track
1,44 km in about 8 minutes = 10,8 km/h (No idea what I did the rest of the track, anyway, my mobile fell first, open, battery loose, was busy to reassemble first... grrrr, ... somewhat after, I decided to measure time anyway
