Depends on what you mean with “the future events”. There are several Websites with upcoming Unicycle Events all over the world. But i think you mean German or Saxon events. Well all websites are in german language.
First there is the page of german unicycling federation: www.einradverband.de/index.php?article_id=614, its for whole germany as well es the german cycling federation at hwww.einrad-bdr.de/?page=termine. Another private page is at einradfahren.de/index.php?module=mod_events&action=index&menu_id=78. www.einradtag.de/node/12 lists events of Saxony.
Here at unicyclist.com we have two threads, the first Terminsammlung 2014 is for whole germany, the second Anstehende Termine Sachsen is only for Saxony.
Did I answer your question with that?
