Kashiwa No Ha Soukai Marathon 2018

Hello!

I'm an Spanish athlete and I'd like to run this marathon. BuT I don't get any information about it.

Do you konw if is there a web or a blog or something like them to get info and, probably, to do my entry.

If anyone ran it and explain more thing about it, perfect!

Thank you very much and best regards from Madrid, Spain.
