For personal running training—either before or after work—there are routes available in Jülich right from your doorstep: those living in the villages can always find opportunities for a “loop” through the paved field paths.
Especially attractive are the urban running paths along the Rur dam—toward the Baggersee Barmen or Baggersee Kirchberg.
Around the research center Jülich, there are diverse routes that lead along fields and through wooded paths.
Experienced runners with higher expectations will find a wide range of options on the Sophienhöhe, including elevation potential.
