Austria Backyard Ultra - Loosdorf TRAIL 2025

The start of the ABU Series 2025!

How many rounds do you dare?

7 laps is more than a marathon.

15 laps is 100 km.

24 laps is 100 miles.


The first Backyard Ultra in the Mostviertel!

The Backyard Ultra mode is very simple.

Every hour the runners start a 6.706 km (=4.167 miles) long course. You have exactly one hour to do this. If you don't finish the round on time and don't start again, you're out!

No late start! Very easy! ;-)


The event runs until there is only one runner left on the course. => open end

The race takes place according to the official Backyard Ultra regulations of the American original.

What awaits you in Loosdorf:


We are delighted to be hosting the first Backyard in the beautiful Mostviertel region.

The run will take place in Loosdorf/Albrechtsberg an der Pielach, near the Prinz company.

The route begins on asphalt for around 300 meters before turning onto a wide single trail along the Pielach. After around 1.5 kilometers, the route turns right onto a dirt track, where there is a turning point after another 500 meters.The route then leads back into the forest, where you have to overcome 150 meters of altitude over the next 1.5 kilometers before you reach the Loosdorf summit cross.

The way back is via forest roads and a small asphalt section back onto the single trail and the settlement road.

With an elevation gain of around 150 meters, the route is quite challenging, but most of it is on single trails, which makes this event an absolute highlight that you shouldn't miss out on.

  • The route is sufficiently marked and secured by marshals. After 10 laps at the latest, you already know the way blindly. 😉

  • The route is mostly on wide asphalt roads. There is only one long, steep climb to run. The rest is flat.

  • In the start-finish area there is space for chairs, a cool box, a sleeping tent or a small pavilion for the runners. First come - first serve! Runners who drop out early must give up space in the start-finish area. This allows runners who are still in the race to move closer to the starting line.

  • Sanitary facilities are available near the start-finish area.

  • Refreshment station is in the start-finish area. There is no aid station on the route.

  • Inappropriate behavior on the running course (especially throwing away trash) will be punished with immediate disqualification.

  • The run takes place at your own risk and on your own responsibility on a route that is not closed off or monitored. On roads, the StVO must be followed and the traffic observed. Vehicles are to be expected on the running track.

The participant is responsible for accidents or injuries of any kind and must take out adequate insurance himself. The landowner and the organizer are not liable for this.
