Eningen unter Achalm周辺のMarathonレース

The Wald(Ultra)Marathon Calw is a 46 km forest ultramarathon beginning in Calw-Altburg, Baden-Württemberg. Scheduled for December, it directs runners onto hilly terrain rather than a fast road course. The longest route extends slightly beyond marathon distance, but the elevation gain and forest trails give it the feel of a mountain endurance run rather than just a few extra kilometers. The course crosses the wooded hills surrounding Calw-Altburg, with Baden and Swabian scenery as the setting. Organizers classify the difficulty as 4 out of 5. The 46 km route demands significant endurance and proficiency on steep or mountain-like terrain. This race is considered a regional ultra classic, emphasizing a challenging day on the trails over achieving a personal best.
