Start/Finish at Ulmerfeld‑Hausmening, entrance to the Forstheide, Amstetten, Lower Austria, Austria
ABU Amstetten (Austria Backyard Ultra – Amstheide-Forstheide 2026) is a charity Backyard Ultra held at the Forstheide near Ulmerfeld‑Hausmening in Amstetten. The event follows the Backyard Ultra open-ended format — “last (wo)man standing” — with a new 6.706 km lap starting every hour and the race continuing until only one runner remains. The organisers present the event as community‑focused and inclusive, welcoming both running beginners and experienced ultrarunners while directing net proceeds to charitable causes.
The course is a mixed forest and trail route with short road sections and is well marked; each lap has approximately 30 metres of elevation gain and a maximum height near 291 m. Support at the venue includes on‑site catering, music/MC entertainment, parking and changing/shower facilities, and a team challenge (teams of three) with La Sportiva prizes for winning teams. Practical notes for competitors include check‑in from 07:00–08:30, an official 09:00 race start, and a requirement for headlamps and reflective clothing for any night running.
