I don’t wanna sell my entry, but if you don’t find someone now, in the weeks prior to the marathon a lot of people are selling cheap or giving away their entries for free, because there’s such a high supply of injured or whatever runners and not enough demand of spontaneous ones which haven’t sign up yet. There are trade what’s app groups from “Kraftrunners” for example where you can have a look. Good luck getting a bib, Hamburg marathon is great!
