Yxbacken Extreme Challenge by E2C

Yxbacken Extreme Challenge by E2C is a hill race held in Norrköping's own ski slope. The race is described as challenging - in 2024, five tough laps were completed in the hill - and it caters both to competitive runners and families through a separate children's race. E2C is the title partner, and the event combines competition, children's activities, and subsequent prize and photo ceremonies.

The 2024 race was held on October 19, and E2C was the title partner for the fourth year. The 2024 children's race had approximately 50 participating children who received medals at the finish line; the winners received wreaths at the award ceremony. Photographer Magnus Media took pictures published on the race's Facebook page. About 300 participants in the first edition; in 2023, the event was photographed by Magnus Andersson (Magnusmedia.nu); the children's race Lilla Yxbackenloppet by E2C was added in 2024.
