Marathon races near Calw

The Bottwartal Marathon is a running weekend held in mid-October in Baden-Wurttemberg's Bottwartal region. It began as a marathon but now includes multiple races. Initially featuring a marathon and a 10K, the event expanded to offer a half marathon, walking events, and a Run & Fun Day for children and students. The organization relies on local club support, with eight clubs from Beilstein, Gronau, Grossbottwar, Murr, Kleinbottwar, Oberstenfeld, Steinheim, and Winzerhausen collaborating through an ORGA team, each club managing its segment. Werner Neumann of Oberstenfeld initiated the race to unite several Bottwartal clubs for a significant running event. The original start and finish were at the Bottwartalkellerei in Grossbottwar, enabling a course with northern and southern loops for the marathon and half marathon. The event later relocated to Steinheim, the "Urmenschenstadt," due to organizational and logistical considerations, with Gerhard Petermann succeeding Neumann as leader. The race has received the most popular marathon medal award six times and is one of Baden-Wurttemberg's largest running events.

The Bottwartal-Marathon is the largest running event in the Bottwartal, a wine-growing region in southern Germany. Its routes pass vineyards and historic half-timbered towns. The race weekend offers many distances beyond just the marathon. Children's, youth, and inclusion races begin the event at Riedstadion in Steinheim an der Murr. Adult runners can select from 5 km, 10 km, a half marathon, 30 km, the full marathon, a relay marathon, or the 52 km Urmensch Ultra. Steinheim an der Murr serves as the primary starting point for longer races, including the 10 km, 30 km, marathon, relay, and ultra. The 5 km race begins in Grossbottwar, and the half marathon starts in Gronau. The marathon follows a loop through the southern and northern Bottwartal. The half marathon features a flat finish for a quicker final stretch. Time limits range from two hours for the 5 km and 10 km races to six hours for the marathon and relay. The 52 km ultra has a seven-and-a-half-hour limit.

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.
