Scratch and Elimination Races

Introduction: Two Classic Mass-Start Disciplines

Scratch and elimination races are among the oldest and most spectacular formats in Track Racing. Both disciplines start as a Start from the Line on the track – all riders begin simultaneously and fight for the best placing. The decisive difference lies in the objective: In the scratch, only the order across the finish line at the end of the race distance counts. In the elimination race (international: Elimination Race, colloquially also Devil or Miss and Out), the last rider each lap is removed from the race at fixed intervals until only one winner remains.

These two formats shape the character of many track competitions – from local club races to the Track World Championships. They are also a fixed part of the Omnium and require not only raw power but above all positioning, timing and tactical intelligence on the 250-meter oval.

Comparison of Both Disciplines

Scratch: Mass start → steady Race Speed → tactical attacks → final sprint → finish order by placing

Elimination: Mass start → Lap 1 (last out) → Lap 2 (last out) → … → Final with 2–3 riders → final elimination sprint

Rules and Distances

In a Scratch Format, all participants start simultaneously. There are no intermediate sprints, no points and no eliminations during the race. What matters is solely the order when crossing the finish line after completing the prescribed distance.

Typical distances at International Cycling Union competitions:

The course layout follows the standardized 250-meter oval. Riders must comply with track rules and positioning; violations such as blocking the fast lane can result in disqualification.

Tactics in Scratch

Scratch races often appear from the outside like "simple riding around" – in fact, the tactics are highly complex:

  1. Early phase (laps 1–20): The field establishes a common pace. Riders save energy in the slipstream and observe competitors. Early attacks are rarely successful but can test weaker riders.
  2. Middle phase (laps 21–45): This is where it is decided whether the race stays calm or breaks up. Powerful riders try to split the field; sprinters keep the pace high enough to prevent overtaking maneuvers.
  3. Final phase (last 5–10 laps): Positioning becomes decisive. Anyone too far back loses contact in the final sprint. The top positions (top 3–5) are worth their weight in gold.

Important: In scratch, the fastest sprinter does not automatically win – anyone riding the last three laps from position 15 has practically no chance of victory, no matter how explosive the final sprint is.

Typical Race Scenarios

  • High-pace sprint race: The field rides fast from the start; sprinters dominate, breakaway riders have little chance.
  • Breakaway race: A small group gets away; the main field hesitates with the chase – often followed by gripping catch-up drama.
  • Fragmented field: Multiple attacks split the peloton; endurance and awareness decide the victory.

Elimination Race: Every Lap Counts

Basic Principle and Rules

In the elimination race, the rule is: After each lap, the last rider is eliminated, measured at the finish line. The race ends when only one rider remains – or at UCI competitions, when the last two or three riders compete against each other in the final sprint.

Key rule characteristics:

  • Mass start like in scratch, but then permanently high intensity
  • Elimination occurs every full lap (250 m on standard track)
  • In case of a tie at the line, a Finish Line Photo decides
  • Riders who are one lap down are not automatically eliminated – what matters is the position at the finish line per lap
  • After elimination, riders leave the track via the inner lane and may no longer influence the race

Elimination intensity: With 20 starters and 250-m laps: 19 elimination laps until the winner – that equals almost 5 km of pure high-intensity effort without a break. Heart rate and lactate remain continuously in the competition zone.

Special Features and Tactical Nuances

The elimination race is tactically more ruthless than scratch, because each individual lap represents a mini-decision:

  1. No hiding: Anyone settling at the back of the field risks elimination every lap.
  2. Pace control: Strong riders set a high pace to eliminate weaker competitors early.
  3. Blocking tactics: Occasionally riders try to slow opponents through lateral movements – commissaires monitor this strictly according to velodrome rules.
  4. Final laps: When only a few riders remain in the race, tactics change: suddenly sprint speed matters more than endurance.

Role in the Omnium and Competition Calendar

Since the UCI omnium reform, scratch and elimination have been a fixed part of the multi-event scoring. Unlike the points race or the individual pursuit, there are no intermediate sprints or time trials here – only placings.

The omnium scoring for both disciplines follows the classic model:

  • Place 1: 40 points
  • Place 2: 38 points
  • Down to place 20 (1 point)

Omnium Day: Discipline Schedule

1
Time trial
2
Individual pursuit
3
Elimination (high load)
4
Scratch (endurance peak)
5
Points race
  1. The elimination race often takes place before the scratch – riders must manage their tactics to score points in both disciplines.
  2. Anyone eliminated early in the elimination can still catch up in the scratch – and vice versa.
  3. Overall omnium winners are often riders who do not dominate any single discipline but consistently finish in the top 5 in both scratch and elimination.

Physical Demands and Equipment

Both disciplines place high demands on anaerobic capacity, sprint power and tactical endurance. Unlike the individual pursuit, there is no pacing strategy over a fixed time – the pace is dictated by the field.

For scratch and elimination, the same equipment requirements apply as for all track races:

  • Fixed gear on track bike without freewheel
  • Typical gearing: 90–104 inches (depending on track and rider profile)
  • Aerodynamic helmets and close-fitting jerseys for minimal air resistance

Training and Preparation

Training Components for Scratch

  1. Long track interval sessions: 40–60 laps at steady pace with simulated final sprint in the last 5 laps.
  2. Group riding: Training in the peloton on the track to perfect positioning and slipstream use.
  3. Sprint follow-ups: After 30 minutes of endurance load, several 200-m sprints – simulates the scratch final.
  4. Tactical briefings: Video analysis of world championship races; recognize patterns in attacks and field reactions.

Training Components for Elimination Races

  1. Elimination simulations: Training groups with deliberately varying pace; last rider each lap must complete an extra sprint.
  2. Repeated Sprint Ability (RSA): 6–8 sprints of 15 seconds with 45 seconds rest – trains the ability to go full gas lap after lap.
  3. Position training: Exercises where riders must work from the back to the front without overheating the field.
  4. Mental training: Visualize each lap as an individual decision; build stress resistance under sustained load.

Checklist: Preparation for Scratch or Elimination

  • ✓ Gearing and equipment checked on race day (fixed gear, tire pressure, wheel condition)
  • ✓ Course plan and start list studied (number of opponents, known sprinters vs. endurance riders)
  • ✓ Warm-up program: 20–30 minutes of increasing intensity, at least two short sprints
  • ✓ Start position noted (scratch: often evenly distributed; elimination: aim for position near the front)
  • ✓ Tactics discussed with coach (attack or wait? Who to watch?)
  • ✓ Hydration and nutrition completed in the hours before the race
  • ✓ Rule knowledge: keep fast lane clear, no intentional blocking
  • ✓ After the race: debriefing – which lap / which maneuver was decisive?

Tip: In the elimination race, it pays to hold second or third position from the slipstream – too far forward means permanent lead work, too far back means elimination danger every lap.

Blocking the upper lane or intentionally slowing opponents leads to warning or disqualification. Commissaires decide in doubt in favor of fair race dynamics.

Notable Riders and Defining Moments

Historically, riders like Bradley Wiggins, Mark Cavendish (in early track years) and Elia Viviani have impressed with dominant scratch performances in the omnium. In the elimination race, riders with a pursuit background often shine – explosive acceleration combined with a high pain threshold.

Spectacular elimination finals with only two remaining riders overtaking each other in every corner are among the most emotional moments of any track world championship. In scratch, it is often long-built attacks and gripping chases that captivate the audience.

Frequently Asked Questions about Scratch and Elimination Races

Question
Answer
What is the main difference between a scratch race and an elimination race?
Both formats start as a mass start on the track, with all riders beginning simultaneously. In the scratch, only the finishing order after the full prescribed distance counts—there are no intermediate sprints, points, or eliminations during the race. In the elimination race (also called Devil or Miss and Out), the last rider across the finish line is removed after each lap until one winner remains, or until the last two or three riders contest a final sprint at UCI events.
How long are typical UCI scratch races for men and women?
At UCI competitions on a 250-metre track, men elite usually ride 15 km (60 laps), while women elite race 10 km (40 laps). Juniors and U23 typically cover 7.5–10 km (30–40 laps). In the omnium, the scratch portion follows the same distances: 10 km for women and 15 km for men, with points awarded according to omnium scoring.
How does elimination work each lap, and what happens in a tie?
Elimination is measured at the finish line after every full lap on the standard 250-metre oval. Being one lap down does not automatically eliminate a rider; what matters is the position at that finish-line check. If two riders are tied at the line, a photo finish decides who is eliminated. After elimination, riders leave via the inner lane and must not influence the race further.
Why is positioning so critical in the final laps of a scratch race?
In the last 5–10 laps, top positions (roughly the top 3–5) become decisive because riders too far back often lose contact in the final sprint. The page stresses that the fastest sprinter does not automatically win: anyone entering the last three laps from around position 15 has practically no chance of victory, regardless of how explosive their sprint is. Energy saving in the slipstream earlier only pays off if you can still move into those front positions before the finale.
How are scratch and elimination scored in the omnium?
Since the UCI omnium reform, both disciplines are fixed parts of the multi-event scoring and award points only by placing—not via intermediate sprints or time trials. First place scores 40 points, second 38, and scoring continues down to place 20 with 1 point. Elimination often comes before scratch on omnium day, so riders must balance effort across both events; early elimination can still be offset by a strong scratch result, and overall winners often finish consistently in the top five in both.
How do the physical demands of scratch and elimination differ?
Scratch over about 60 laps leans more aerobic (around 55 percent aerobic, 35 percent anaerobic lactic, and 10 percent anaerobic alactic in the final), with wave-like intensity that peaks late. Elimination with roughly 20 starters is shorter but stays consistently hard: about 30 percent aerobic, 55 percent anaerobic lactic, and 15 percent anaerobic alactic. With 20 starters that means nearly 5 km of high-intensity effort across 19 elimination laps, with heart rate and lactate remaining in the competition zone throughout.
Which tactics and start positions help most in an elimination race?
Settling at the back risks elimination every lap, so strong riders often force a high pace early to remove weaker competitors. Holding second or third wheel in the slipstream is often smarter than leading every lap, because constant lead work burns energy while sitting too far back invites danger each time. Commissaires strictly police blocking or slowing opponents with lateral moves; blocking the upper lane or intentional obstruction can mean a warning or disqualification.
