In 2018, Ecotrail Brussels will be a race part of the 2018 Delhalle Challenge.
The Delhalle is the oldest nature running challenge in Belgium. It gathers a total of 14 races spread out over the whole year. This challenge was started in 1982 and the name Delhalle comes from Leon Delhalle who has supported the whole project from the very begining and passed away in 1981.
The motto of the xg-hallenge is "organized by runners and for runners". And the high quality of the events has made the success of this circuit.
