, Switzerland. He had been frustrated that his hotel was only busy during the summer months.

. However, with increased numbers this led some guests to search for new diversions. In the early 1870s some adventurous Englishmen began adapting boys' delivery sleds for recreational purposes. However, when they began colliding with pedestrians in the icy lanes, alleyways and roads of St. Moritz, this led to the invention of "steering means" for the sleds. The basic bobsleigh (bobsled) consisted of two crestas (skeleton sleds) attached together with a board that had a steering mechanism at the front. The ability to steer meant the sleds could make longer runs through the town. Longer runs also meant higher speeds on curves. Local sentiment about these informal competitions varied, but eventually complaints grew so vociferous that Badrutt had to do something. His solution, in the late 1870s, was to build a basic natural-ice run for his guests outside the town near the small hamlet named Cresta. He took action because he did not want to make enemies in the town, and he had worked hard and invested a lot of time and money in popularizing wintering in St. Moritz, so he was not going to let boredom induce customers not to visit the area.

It is not known how much the original track evolved in the early years as the three sports matured and stabilized. The first club was formed in 1897, and the first purpose-built track solely for bobsleds opened in 1902 outside St. Moritz. Over the years, bobsleigh tracks evolved from straight runs to twisting and turning tracks. The original wooden sleds gave way to streamlined fiberglass and metal ones. The

. Bobsleigh is also contested at American, European, and World Cup championships. Germany and Switzerland have proven the most successful bobsleighing nations, measured by overall success in European, World, World Cup, and Olympic championships. Since the 1990s Germans have dominated in international competition, having won more medals than any other nation. Italy, Austria, Canada and the United States also have strong bobsleigh traditions. Bobsleighs can attain speeds of , with the reported world record being .

, including crew, is (4-man), (2-man), or (2-woman), which can be reached via the addition of metal weights. The bobsleighs themselves are designed to be as light as possible to allow dynamic positioning of mass through the turns of the bobsleigh course. Although bobsleighs once were ridden by five or six, crews were reduced in the 1930s to either two or four people. The four-person crew consists of a pilot, a brakeman, and two pushers. Athletes are selected for their speed and strength, which are necessary to push the sleigh to a competitive speed at the start of the race. Pilots must have the skill, timing, and finesse to steer the sleigh along the path, or "line", that will produce the greatest speed. In modern bobsleighs, the steering system consists of two metal rings that actuate a pulley system located in the forward cowling that turns the front runners. For example, to turn left, the pilot would pull the left ring. Only subtle steering adjustments are necessary to guide the sled; at speeds up to , anything larger would result in a crash. The pilot does most of the steering, and the brakeman stops the sled after crossing the finish line by pulling the sled's brake lever. Women compete in women's bobsleigh (which is always two-woman) and men in both two- and four-man competitions. Women were confirmed as being able to compete in any four-"man" bobsleigh event, as from 25 September 2014, either as part of a mixed-sex team or an all-female team. However, because women are on average lighter than men (and thus at a competitive disadvantage in a gravity sport), and because most sliding nations have fewer women able to compete than men, this option has not proved popular with teams.


Monobob

A single-person bobsleigh is called a "monobob". Single-person sleds were introduced into international competition for both adaptive bobsleigh (for athletes who are able to drive a sled but not push) and as a youth sport (for younger athletes who have not yet developed the ability to push a heavy two- or four-person sled). After the
2018 Winter Olympics , nations = 93 , athletes = 2,922 (1,680 men and 1,242 women) , events = 102 in 7 sports (15 disciplines) , opening = , closing = , opened_by = President Moon Jae-in , cauldron = Kim Yun-a , stadium = Pyeongchang Olympic Stadium , winte ...
, the International Olympic Committee and the IBSF agreed to add women's monobob as an Olympic sport for the

, so that there would be an equal number of women's and men's events in bobsleigh. Prior to the 2020–21 competitive season, monobobs were traditionally constructed on one-piece chassis. Starting with the 2020–21 season, competitors in IBSF-sanctioned races must use articulated (two-section) monobobs manufactured by the IBSF's sole source sled builder, iXent. The sled must weigh a minimum of without the athlete (but including timing equipment and any ballast weights) and a maximum of including the athlete; runners are the same as for two-person bobsleighs. This implies a maximum athlete weight limit of .


Racing

Individual runs down the course, or "heats", begin from a standing start, with the crew pushing the sled for up to before boarding; though the pilot does not steer, grooves in the ice make steering unnecessary until the sled leaves the starting area. While poor form during the initial push can lose a team the heat, it is otherwise rarely, if ever, decisive. Over the rest of the course, a sleigh's speed depends on its weight, aerodynamics, runners, the condition of the ice, and the skill of the pilot. Race times are recorded in hundredths of seconds, so even seemingly minor errors – especially those at the beginning, which affect the remainder of the heat – can have a measurable impact on the final race standings. The men's and women's standings for normal races are calculated over the aggregate of two runs or heats. At the Olympic Winter Games and World Championships, all competitions (for both men and women) consist of four heats.

Safety


Brain trauma

Sledding at a competitive level involves sledders repeatedly subjecting themselves to high-G forces and multiple small collisions of their head into their helmet as sharp turns are taken. Additionally, when mistakes happen and the sled crashes, there are no "seatbelts" or other protections; the sledders can simply be falling down the course at high speed with their helmet grinding along the surface or bouncing off the interior of the sled. One sledder described his experience during crashes as being equivalent to his head being inside a jet engine. Even ignoring crashes, repetitive shaking from small imperfections in the course is hypothesized to cause small tears in the brain, especially if performed repeatedly. The culture of competitive bobsledders (especially before this danger was recognized) also made injured participants hesitant to speak up and request breaks, fearful of being dropped from the team. Bobsledders who train frequently have reported issues such as chronic headaches, a heightened sensitivity to bright lights and loud noises, forgetfulness, a "mental fog", and psychological problems. Repeated mild brain trauma has caused issues for boxers, rugby players, and football players with

A brain scan of one bobsledder, Christina Smith, revealed damage to the rear and frontal lobes, consistent with micro-tears in the brain's white matter.
