Germans have dominated international competition during the 1990s, winning more medals than any other nation. Bobsleigh is also popular in Italy, Austria, the United States, and Canada. Bobsleighs may reach speeds of up to 150 km/h (93 mph), with a purported world record of 201 km/h (125 mph). In fact, Germany has held the top spot in both two-man and four-man events since the 1992 Winter Olympics in Albertville. The United States has been second each time, while Russia has been third. The IBSF World Championships are held every year. The first took place in Switzerland in 1954; before that time, national champions were determined by domestic competitions. Since those early days, the sport has become popular worldwide, with nations such as Australia, Canada, France, Germany, Italy, Japan, South Korea, Sweden, and the United States competing regularly in the sport. At the Olympic level, Germany's two-man team is led by Felix Merkel and Christian Poser, while their four-man squad is made up of Alexander Kasjanov, Andre Schulze, Markus Waldherr, and Tobias Wendt.
