I have know about this since entering my 10km race - my understanding is you can enter for this after doing the race i am in. Not thinking M but 10km.
Reasons for doing it
1) we are going to go to Easter Island and what a great way to see the island so kills two birds with one stone
2)my partner might join me on the 10km.
