Listen to me horribly mispronounce Bart's name, his kind correction, and then Bart explain the situation in Belgium:

"Starting today, we have entered the 'Exit Strategy' in Belgium - groups of 20 can go for a run - but no competitions until at least 7/31."

Western Europe has a VERY organized trail running scene - routes not only have their own webpages, but are all are clearly marked and identified.  Bart explains the difference between "GR" routes, and the new "Extra Trail" designation.
