How to delete a tournament?

Hi there.
I accidently created a tournament with wrong settings. How can I delete it again? It takes place in 4 days. I don't even see it listed on the arena schedule. I think, because it's too far off in the distance.
Thanks!

I routinely create a weekly tournament 5-6 days in advance and it always shows up on the team page. Go to your team page and you will see it. Then you can just edit it

Hi Whitesn4ke
I don't have a team. The tournament is not listed at the team page. I am member of exactly one team which is not related to the tournament whatsoever.
But thanks for your idea.

I just found it !!
If anyone of you should ever run into this: Simply go to arena tournaments. Then, right under the rankings - left hand side, there is an entry "My tournaments".
