Once again, the 37th edition features a 4-mile run from Haren to Groningen. The Menzis Groningen 4-mile run will take place this year on Sunday 8 October. The day before the Groningen 4-mile, you also get the chance to take part in the 4Mijl4You. Here you can do the exact same course on your roller skates, in a cool go-cart, or just walking.
