Mountainbiking in Vienna

I'm reaching out for fellow mountainbikers in and around Vienna. For my first activity here as a consul of the Vienna biking group I have chosen a not so difficult tour. It is a round trip of about 30 km and will take us appr. 2,5 hours. Breaks not included ;-) We will do Protected content . Starting point is the train station in Liesing. We'll meet just outside the station near the post office at 10 am.
Please attend only if you have a mountainbike. The tour is not suitable for streetbikes, roadbikes or citybikes. There are some roots and rocks on our way.
I also insist in wearing a helmet while on the bike.
As there is no place to get food and drinks along the way (except one, which is too near from the starting point), please bring along some snacks and plenty of water or whatever you choose to drink while doing sports. I did the tour today and found a nice place where we can have a break and eat our snacks.
I want to make clear, that everybody is responsible for his own safety and health. I am just the one who guides this tour and takes care, that we can get along as a group and nobody gets lost ;-)
