With speeds exceeding 150 km/h and races decided in fractions of a second, bobsleigh is known as the 'F1 on Ice.' At the 2026 Milano-Cortina Winter Olympics, athletes showcased thrilling races that pushed the limits of human capability. In this fierce competition, it's not just the athletes' strength and courage that determine the medal color. Bobsleigh is evolving into a crystallization of sports science, integrating the latest training trends and technological advancements. From minute air resistance to the friction between the runner and the ice, and the athletes' explosive start power, every element must be precisely designed and managed to achieve top records. This article will delve into how such scientific approaches influenced the competition at this Olympics.
The 'start,' approximately the first 50 meters after pushing off, is crucial in bobsleigh, dictating more than half of the final result. Athletes must generate explosive speed and acceleration during the push and boarding phases. To achieve this, modern bobsleigh training provides programs optimized for each athlete's characteristics through a data-driven scientific approach. Essential training includes not only high-intensity weight training but also exercises that build explosive power, such as jump squats, hurdle drills, and Olympic lifts. In particular, personalized training methods are being introduced, such as adjusting training intensity based on analysis of athletes' muscle characteristics and genetics. Furthermore, efforts to shave off even 0.01 seconds continue, with experiments dividing the optimal boarding points into 1-meter intervals to identify the best acceleration and intensively training those specific boarding points.
Bobsleigh training faces significant limitations due to climate, time, and space. There are not many bobsleigh tracks worldwide, and opportunities for training on actual competition tracks are limited. To overcome these hurdles, Virtual Reality (VR) simulators have become key training tools. VR simulators virtually replicate over 10 competition tracks worldwide, including the 2026 Milano-Cortina Olympic track, allowing athletes to experience driving as if they were on the actual course. They reproduce the sled's shaking, tilting, and even the sound of friction with the ice surface, providing a highly immersive training environment. Additionally, artificial environment facilities like positive and negative pressure chambers enable acclimatization training at high altitudes and physical recovery, significantly contributing to athletes' condition management and performance enhancement.
While a bobsleigh might appear simple, it is an epitome of advanced scientific technology. Particularly, aerodynamic design to minimize air resistance is as crucial as in F1 racing cars. Lightweight new materials like carbon fiber are used to reduce the sled's weight while maintaining robustness, and the optimal exterior shape is determined through Computational Fluid Dynamics (CFD) analysis and wind tunnel experiments. The shape of the sled's front nose plays a key role in reducing air resistance, and designs with sharp angles, similar to stealth aircraft, are part of these efforts. These technological advancements create decisive differences in competitions decided by 0.01 seconds.
Another key factor determining bobsleigh's speed is the runner (blade) and the athletes' spikes. Research to optimize the friction between the runner and the ice surface is constantly underway. Research into domesticating the equipment for micro-processing the surface of the sled runners is also active, which is said to bring a 0.2-0.3 second improvement in record times. The spikes embedded in the athletes' shoe soles are also products of advanced technology. In Germany, global companies like BMW utilize 3D printing technology to analyze each athlete's driving characteristics and foot pressure, producing custom spike plates. They also develop studs by impregnating special alloys with ionic nitrogen to ensure maximum grip and wear resistance. These minute technological differences create tremendous speed differences on the ice.
Bobsleigh is a dangerous sport, with speeds approaching 150 km/h and centrifugal forces of several tons. Therefore, technological advancements for athlete safety are also addressed with importance. Innovations in safety equipment, such as seatbelts to prevent rollovers inside the sled and HIP (Head Impact Protector) development to prevent head injuries, are continuously being made. Furthermore, Omega, the official timekeeper of the Olympics, introduced the first-ever 'Virtual Photo Finish' for bobsleigh at the 2026 Milano-Cortina Winter Olympics, combined with AI-powered computer vision technology, to deliver more dynamic insights into critical moments and the flow of the competition. Thus, bobsleigh is not only a sport challenging human limits but also a stage for constantly evolving cutting-edge technology, setting the direction for future winter sports.
Bobsleigh is akin to art, created by the combination of athletes' relentless efforts and cutting-edge scientific technology. The dedication of athletes striving for 0.01-second improvements, alongside scientists and engineers supporting them, creates astonishing dramas every time. The bobsleigh competitions at the 2026 Milano-Cortina Winter Olympics vividly demonstrated the fruits of these efforts, inspiring anticipation for the unlimited development potential of the bobsleigh discipline.

Q1: Why is the bobsleigh start so important?
A1: Bobsleigh has no engine, so the initial acceleration gained by athletes pushing the sled during the start phase significantly impacts the overall race time. In actual competitions, the start ranking often closely matches the final ranking.
Q2: How are VR simulators used in bobsleigh training?
A2: VR simulators virtually replicate various bobsleigh tracks worldwide, allowing athletes to repeatedly practice and familiarize themselves with course navigation techniques without time and space constraints. They provide a training effect similar to real competition by reproducing the shaking, tilting, and friction sounds of the actual track.
Q3: Why are bobsleigh sleds so expensive?
A3: Bobsleigh sleds must be lightweight yet strong, and they are custom-built incorporating advanced scientific technologies such as aerodynamic design, use of new materials, and precise runner processing. The cost of a four-person sled can exceed 100 million Korean Won.
Q4: How is South Korea contributing to bobsleigh technology development?
A4: South Korea has installed positive and negative pressure chambers and virtual reality simulation training facilities at the Pyeongchang Sliding Center to support national team training, a world-first initiative. Additionally, efforts are being made in equipment technology development, such as research for domesticating sled runner surface processing equipment.
