Roadbike ultramarathons

Hello

I am writing in English as I am not using German at all (maybe I know this langueage a bit, but find much more efficiency in English).

At the begining I would like to present myself, I am from Poland, I participate in localy organised roadbike ultramarathons. I am looking for forums, information and people engaged in organising roadbike ultramarathons events in Austria

I would be appreciated if you share any information (links, contacts) that would allow me to get demanded information.

regards
