Bobsleigh
Winter sliding sport in which teams of 2 or 4 push a streamlined sled down a twisting refrigerated ice track, reaching speeds of 150+ km/h.
What is Bobsleigh?
Bobsleigh is a team winter sport in which crews of 2 or 4 athletes push a streamlined sled at the start of a refrigerated ice track, jump in, and steer down the twisting course reaching speeds of 130-155 km/h. The sport was invented in Switzerland in the late 1870s when a St Moritz hotel guest attached two skeletons together with a plank. Modern bobsleighs are hi-tech aluminium and composite shells with steel runners; the pilot steers via ropes/cables connected to the front runners, and the brakeman pulls the brake at the finish. The sport has been in the Winter Olympics since 1924 (2-man since 1932; women's 2-woman added 2002; women's monobob 2022). Track lengths ~1,300-1,700 m with 15-20 turns; G-forces in tight corners exceed 5g. Germany (with Kaillie Humphries switching from Canada, and Francesco Friedrich for men) dominates the modern era.

How it works
Objective
Complete the track in the fastest time; win by lowest sum of times across all runs.
Match structure
Competition = 4 runs (2 per day) over 2 days. Team pushes off, jumps in, pilot steers down 15-20 turns; brakeman brakes at finish. Fastest total time across runs wins.
Rules
Basic rules
Fast push start
Team pushes sled for ~50 m from starting handles; then all jump in — first pusher (or brakeman) in last.
Pilot steers
Only pilot handles ropes/steering cables.
Complete the track
Sled must cross finish upright with all crew still onboard.
Brake at finish
Brakeman pulls brake handle to slow sled after finish line.
4 runs summed
Winter Olympics + World Champs use 4-run format.
Weight minimums
Sled + crew total mass regulated: 2-man 390 kg, 4-man 630 kg.
Advanced rules
Runner grinding banned
Only IBSF-approved runner steel and blade profile — polishing techniques regulated.
Team weight (2-man/4-man/2-woman)
Fixed maximum crew + sled weight; teams add ballast to reach max for stability.
Aerodynamics
IBSF regulates sled shape; wind-tunnel tested but tightly bound to spec.
Sled inspection
Post-race inspection ensures compliance with dimensions/weight/runner spec.
Progressive fields
Top 20 in first 2 runs advance to final 2 runs at Olympics.
Scoring
Fastest sum of times across 4 runs wins.
| Action | Points |
|---|---|
| Run time | Recorded to 0.01 sec (0.001 unofficial) |
| 4-run total | Sum of all 4 run times; lowest wins |
| Photofinish | In case of tied cumulative to 0.01 sec, use unrounded times |
Win condition · Lowest cumulative time across all 4 runs wins.
Playing area
Called
artificial ice track
Dimensions
1,300-1,700 m long; typically 15-20 turns; vertical drop 100-150 m.
Refrigerated concrete track with 5-10 cm ice layer. Banked curves (some near-vertical) shaped in concrete substrate.
Equipment
Bobsleigh
Aluminium and composite shell; 2-man: 165 cm long, 170 kg minimum. 4-man: 250 cm long, 210 kg min. Steel runners.
Helmet
Full-face helmet with chin protection.
Suit
Aerodynamic Lycra racing suit.
Spiked shoes
Push-start spikes for start acceleration.
Ropes / steering cables
Pilot pulls left/right ropes attached to front runners.
Brake handle
Brakeman pulls at finish to slow sled.
Officiating
IBSF timing rules; photocells at start/finish for split times.

- Track Judges
- IBSF Race Committee
- Push Judges (start)
Strategies
Great start = fast time
Start push accounts for ~30% of run time; explosive start critical.
Racing line
Optimal turn entry/exit — high entry, apex at 60% turn.
Minimize steering
Every steering correction slows sled — pilot aims for smooth line.
Runner temperature
Cold runners glide faster; teams monitor runner temp.
Terminology
- Pilot
- Driver — steers sled with ropes/cables.
- Brakeman
- Last person in — pulls brake handle at finish.
- Pusher
- Middle team member (4-man) — pushes at start, then loads.
- Push start
- First 50 m — team pushes sled from starting handles.
- Kreisel
- 360° full-loop turn — most famous at Königssee.
- Runners
- Steel blades under sled contacting ice.
- Split time
- Time at intermediate points on track.
- Loading
- Team jumping into sled after pushing.
- Sled inspection
- Post-race check for dimensions/weight/runner compliance.
- Monobob
- Solo bobsleigh event for women, added Beijing 2022.

Frequently asked
How fast do bobsleighs go?+
150-155 km/h (93-96 mph) on the fastest tracks (Whistler, St Moritz). G-forces in tight corners exceed 5g.
How many people in a bobsleigh?+
2-man / 2-woman: pilot + brakeman. 4-man: pilot + 2 pushers + brakeman. New (2022) event: Monobob (solo, women only, Olympic).
Is bobsleigh Olympic?+
Yes — since first Winter Olympics 1924 for men (2-man and 4-man). Women's 2-woman since 2002. Monobob (solo women) added Beijing 2022.
How dangerous is bobsleigh?+
Serious injuries and deaths do occur but are rare with modern equipment. Nodar Kumaritashvili (Georgia luge) died in Vancouver 2010 practice; sled crashes usually result in bruises or broken bones.
Who won 'Cool Runnings' Jamaica?+
The 1988 Jamaica Bobsled Team competed in Calgary and famously crashed but became global folk heroes — inspiring 1993 Disney film. Jamaica has continued to compete in every Winter Olympics since.
How does the pilot steer?+
Pilot pulls left/right ropes/cables connected to front runners — very subtle inputs (~2-3 mm rope pull) redirect the sled.
