Endurance Loop Event

Norm's Helium Loops is an endurance running event focused on vertical gain and repetition. The event operates for a maximum duration of 12 hours, spanning from sunrise to sunset. Participants attempt to complete as many laps as possible on a 5.5 km loop course. Each individual loop includes 250 m of climbing, and there is no specific time limit enforced for the completion of a single lap.

Runners can aim for specific distance milestones based on the number of completed loops:

  • 4 loops for a half marathon distance with 1,000 m of elevation gain
  • 8 loops for a marathon distance
  • 18 loops for a 100 km distance

The event also features a specific category called Norm's Half Marathon. This is a four-loop race where participants can begin their effort at any time within a specified four-hour window.

The event provides a fully marked course to guide runners. The race headquarters is located indoors and includes facilities such as toilets, showers, and refreshments. First aid cover is present throughout the duration of the event. All participants receive a memento for taking part, and prizes are awarded to the overall male and female winners. For those requiring accommodation, camping on Saturday night is available upon request. Visit the organization's website for the most recent information.
