Peter Stocker from SV Erndtebrück took in Osrblie at the Summer Biathlon World Championships in 1998 in part and arrived there in three races used. In the sprint race he was 57th, 52nd in the pursuit race and with Gerald Zielinsky , Frank Röttgen and Martin Kalpein 13th and last in the relay race. Nationally, he was one of the most successful summer biathletes in the early 2000s. At the first German championships in Clausthal-Zellerfeld in 1999 , he won the silver medal in the small-caliber sprint behind Roman Böttcher . A year later he was able to become runner-up again behind Böttcher in the small-caliber sprint in the same place, as this time in the pursuit race. In 2001, Stöcker won silver again in Jagdhaus , now with the small-bore squadron of the Westphalia regional association. His daughter Nina is also a successful young athlete in athletics and summer biathlon.
