Bobsleigh, also called bobsled, is an exciting winter sport. Teams of two or four athletes race down a special icy track. They use a super-fast, gravity-powered sleigh. The goal is to finish the twisting, turning course in the quickest time. The International Bobsleigh and Skeleton Federation helps organize these thrilling races worldwide.
This sport began in the late 1800s in St. Moritz, Switzerland. Rich visitors from Victorian Britain first used simple sleds. These sleds were like those used for deliveries or toboggans. Over time, these grew into the bobsleighs, luges, and skeleton sleds we know today. At first, people raced on town streets. But it became too crowded, so bobsledding moved to special tracks. The Cresta Run is the oldest track. It has hosted two Olympic Winter Games and is still used today.
Modern bobsleigh teams aim for the fastest total time over several runs. The four-man event has been in almost every Winter Olympics since 1924. The two-man event started in 1932. Women first competed in a two-woman event at the 2002 Winter Olympics. A new women's single-person event, called monobob, joined the 2022 Winter Olympics.

What's in a Name? The Story of Bobsleigh
The name "bobsleigh" comes from how early racers moved. They would "bob" their bodies back and forth inside the sled. This helped them gain more speed!
The Exciting Start of Bobsleigh History
How Bobsleigh Began
People have enjoyed sledding for a long time. But bobsleigh as a sport started more recently. It began thanks to a hotel owner named Caspar Badrutt in St. Moritz, Switzerland. He wanted his wealthy English guests to stay all winter. To keep them entertained, he offered fun activities.
In the 1870s, some adventurous guests started using delivery sleds for fun. They raced these sleds down the icy streets of St. Moritz. Soon, they added steering to their sleds. This made the rides longer and faster. However, racing in town became a problem. People worried about safety with sleds speeding through the streets. So, Mr. Badrutt built a special ice track outside of town. This track, called Cresta, was just for his guests to enjoy their new sport safely.
Bobsleigh Becomes a Competitive Sport
Formal bobsleigh races began on the Cresta Run in 1884. This track was built each year by guests and local people. It is still used today and has hosted skeleton events at two Winter Olympic Games. The Cresta Run is special because it uses natural ice, not artificial cooling.
The first bobsleigh club started in 1897. A track built just for bobsleds opened in 1902. Over time, tracks changed from simple straight lines to complex twisting courses. The sleds also improved. They went from wooden designs to sleek fiberglass and metal ones.
The International Bobsleigh and Skeleton Federation (IBSF) was created in 1923. Men's four-man bobsleigh was part of the very first Winter Olympics in 1924. The men's two-man event joined in 1932. Bobsleigh has been in almost every Winter Olympics since then. Women's bobsleigh races started in the US in 1983. The two-woman event became an Olympic sport at the 2002 Winter Olympics.
Countries like Germany and Switzerland are very strong in bobsleigh. Germany has won many medals in international races since the 1990s. Italy, Austria, Canada, and the United States also have great bobsleigh teams. These fast sleds can reach speeds of over 150 kilometers per hour (93 mph)! The world record speed was 157.06 km/h (97.59 mph) in 2019.
Bobsleigh in the Modern Era
Amazing Bobsleigh Tracks
Today's bobsleigh tracks are built from concrete and covered with a thick layer of ice. They are designed to be super fast and challenging. Each track must have at least one straight part and a "labyrinth." A labyrinth is a section with three quick turns, one after another.
A good modern track is usually about 1200 to 1300 meters (3,900 to 4,300 feet) long. It has at least fifteen exciting curves. Sleds can go faster than 120 kilometers per hour (75 mph) on these tracks! In some curves, the athletes feel a force up to 5 times the force of gravity. This is like feeling five times your own weight! Many bobsleigh tracks are also used for luge and skeleton sports. Some tracks even let tourists experience a bobsleigh ride.
High-Tech Sleighs and Skilled Crews
Modern bobsleighs are made from light metals and strong composite materials. They have special steel runners and an aerodynamic shape. This design helps them cut through the air quickly. A four-person sled can be up to 3.80 meters (12.5 feet) long. A two-person sled is up to 2.70 meters (8.9 feet) long.
In 1952, rules were added for the maximum weight of the sled and crew. This makes the competition fair for all teams. The maximum weight for a four-man team is 630 kg (1,389 lb). For a two-man team, it's 390 kg (860 lb). For a two-woman team, it's 340 kg (750 lb). Teams can add metal weights to reach these limits.
Bobsleigh crews used to have five or six people. But in the 1930s, this changed to two or four people. A four-person crew has a pilot, a brakeman, and two pushers. Athletes are chosen for their speed and strength. They need this to push the sled fast at the start. The pilot is very important. They steer the sled with skill to find the fastest path down the track.
The steering system uses two metal rings. These rings control a pulley system that turns the front runners. Pilots make small, careful adjustments to steer. Big movements at high speeds could cause a crash. After crossing the finish line, the brakeman pulls a lever to stop the sled. Women compete in two-woman bobsleigh. Men compete in both two- and four-man events. Since 2014, women can also be part of four-person teams.
Monobob: Racing Solo
A "monobob" is a bobsleigh for just one person. These single-person sleds were first used for adaptive bobsleigh. This is for athletes who can drive but not push a heavy sled. They were also used for younger athletes. These younger athletes might not be strong enough yet to push a two- or four-person sled.
After the 2018 Winter Olympics, women's monobob became an Olympic sport. It was added for the 2022 Winter Olympics. This helped make the number of women's and men's bobsleigh events equal. Modern monobobs are made by a special builder. They must weigh at least 162 kg (357 lb) without the athlete. With the athlete, the total weight can be up to 247 kg (545 lb).
How Bobsleigh Races Work
Races start with the crew pushing the sled for up to 50 meters (164 feet). Then they jump in! The pilot doesn't need to steer much at the very start. Special grooves in the ice guide the sled. A strong push is important, but it's rarely the only thing that decides the winner.
After the push, the sled's speed depends on many things. These include its weight, how aerodynamic it is, the runners, the ice condition, and the pilot's skill. Race times are measured in hundredths of a second. Even tiny mistakes can change the final results.
Most races have two runs, or "heats." The times from these two runs are added together to find the winner. At the Olympic Winter Games and World Championships, all competitions have four heats. The team with the fastest total time wins the gold!
