[1] The European Ultramarathon Cup began after the fall of the Berlin Wall before that year's Rennsteiglauf, at the time the biggest sporting event in East Germany.
Representatives from the Rennsteiglauf, the Biel running days, and the Swabian Alb Marathon met to organize the first series.
It was expanded to an annual series with a yearly award ceremony in 2002.
The weighting factor was calculated based on the best finishing times during the previous year and is normalized on the finishing time of the 100 km Del Passatore.
The runners were ranked based on their average score.
