The Skeleton sled and athlete combined weight limits are 120 kg for men and 92 kg for women with ballast allowed to meet maximum sled weights.

2.1 The Sled

Different

IBSF

Bobsleds are precision-engineered machines constructed primarily from steel and fibreglass composites. Key specifications vary by event: Monobob: Standardised IBSF-supplied sled, weight 162 kg (357 lb). All athletes use identical sleds to equalise equipment, making the event purely about driving ...

If an athlete is under the maximum combined weight, ballast may be added to the sled up to the sled weight limit.; Sled dimensi...

3.1 Track Specifications

Different

IBSF

Bobsled tracks are purpose-built, artificially refrigerated ice channels. Track construction uses reinforced concrete with embedded ammonia or brine refrigeration pipes to maintain ice temperature.

IBSF

Track length: 1200–1650 m (3937–5413 ft) from the skeleton/bobsled start to the finish; Vertical drop: 100–150 m (328–492 ft) from start to finish; Number of curves: 15–20 curves, including S-curves, hairpins, and high-banked turns

3.1 Venue Specifications

Different

Purpose-built artificially refrigerated ice tracks.

IBSF

Races held on artificially refrigerated tracks (shared with bobsled and luge).

4.1 Competitors and Officials

Different

IBSF

Two-man/monobob: 1 pilot + 1 brakeman (two-man) or 1 pilot (monobob). Four-man: 1 pilot + 1 brakeman + 2 pushers.

Olympic and World Championship events consist of 4 runs over 2 days (2 runs per day). World Cup and lower-tier events may use 2 runs in a single day.

IBSF

Olympic and World Championship: 4 runs over 2 days (2 runs per day). Combined cumulative time of all 4 runs determines the final ranking.; World Cup: 2 runs in a single day (combined time). Top 20 after run 1 advance to run 2.; Training: 3–6 official training runs over the days preceding competit...

5.1 Core Rules

Different

IBSF

Start: crew pushes sled from standstill for approximately 50 m before loading. Start time (measured at a specific point) is a critical competitive factor.

IBSF

Athlete must cross the finish line on the sled. Separating from the sled before the finish results in a DNF.

6.1 Scoring System

Different

IBSF

Combined time of all runs (typically 4 runs) determines final ranking. Times recorded to 1/100th second.

IBSF

Combined time of all 4 runs determines final ranking. Times recorded to 1/100th second.

6.2 Split Times

Different

IBSF

In addition to start and finish times, intermediate split times are recorded at designated points along the track (typically 3–5 splits). These help analysts assess where time is gained or lost and are broadcast to spectators in real-time.

IBSF

Intermediate (split) times recorded at 3–5 points along the track; Start time (0–50 m) is a key split, as the push phase is the only athlete-powered portion of the run; Split times help coaches and athletes analyze performance through specific track sections

7.1 Infractions and Consequences

Different

IBSF

Key Fact: Brake applied before finish results in disqualification for that run.

IBSF

Key Fact: Runner temperature exceeds limit results in DSQ for that run.

8.1 Safety Protocols

Different

IBSF

Track walls lined with specialized ice and concrete. High-G-force curves profiled to contain sleds.

IBSF

Chin guard helmet mandatory due to head-first position. Track padding at high-impact zones.

Section 3: Playing Area

Different

IBSF

Bobsled tracks are purpose-built, artificially refrigerated ice channels. Track construction uses reinforced concrete with embedded ammonia or brine refrigeration pipes to maintain ice temperature.

IBSF

Track length: 1200–1650 m (3937–5413 ft) from the skeleton/bobsled start to the finish; Vertical drop: 100–150 m (328–492 ft) from start to finish; Number of curves: 15–20 curves, including S-curves, hairpins, and high-banked turns
