5,000 runners have already registered for this year’s edition of the ING Night Marathon in Luxembourg, taking place on May 27. This means that there are no more starting numbers for the marathon, semi-marathon or the very popular team-marathon available.

The only categories still available are the mini-marathon, the mini mini-marathon and the 5k Run for Success. It appears the 2017 edition of Luxembourg’s most famous marathon promises to be a big one.
