Whether you call it bobsleigh or bobsled, the sport originated in St. Moritz, Switzerland, during the late 1860s as a recreational activity for English tourists who modified traditional delivery sleds for racing. The sport evolved from these informal races on icy village streets to more organized competitions, leading Casper Badrutt to build the Cresta Run in 1884, the world's first natural ice track. The modern bobsleigh was developed in 1888 by connecting two skeleton sleds with a wooden board and adding a steering mechanism. Today, only about 17 professional bobsleigh tracks exist worldwide, with the St. Moritz-Celerina Olympic Bobrun remaining the last major natural ice track, hand-built annually from snow and water.

The sport is defined by extreme physical demands and precise engineering, with athletes experiencing G-Forces (gravitational force) up to 5G during high-speed turns. These forces can be so intense that they may compress an athlete's spine over time. Success in bobsleigh often depends on the initial push, leading teams to recruit world-class sprinters to accelerate the heavy sleds—which can weigh up to 630 kilograms (approximately 1,400 pounds) for a four-person team. While early participants used a rhythmic "bobbing" motion to increase momentum—giving the sport its name—modern teams remain as still and aerodynamic as possible to minimize air resistance and maintain speeds that can reach 90 miles per hour.
