Tököli Parkerdő provides the setting for this road running festival with an ultra heart, based at PLACC Rendezvényközpont. The XX. Szufla Futófesztivál is the "SZUFLA (Szigethalmi Ultrafutók) running festival," and this is significant as it also marks the 20th anniversary of the local ultrarunning club.
The day combines challenging runs with a community atmosphere. The course begins and ends at PLACC, featuring road sections through the park forest. It attracts ultra runners, newcomers, and children. The event has become the area’s “iconic running race,” and this edition is being observed as a major festive occasion, rather than simply another race day.
