Reach and hold a measured flying speed, then decelerate safely

Maximum locomotor speed is assessed after the departure phase, when the athlete is already upright. This lesson uses a measured 30 m build-up followed by a 20 m fly zone divided into entry and exit halves. The goal is not simply to attack the first fly gate: the learner arrives tall, cycles the limbs without reaching, preserves cadence across both halves, continues beyond the last sensor and then eases down across a long runoff. Comparing entry-half and exit-half velocities reveals whether speed was maintained or merely peaked and faded. A coach decides eligibility, environmental limits, build-up length, target intensity, repetition count and recovery; the learner executes the pass, recognises tension or asymmetry and never chases an extra high-speed exposure.

What you will produceThe learner completes two supervised 30 m build plus 20 m fly passes whose entry and exit halves are valid, closely matched and followed by controlled long-runoff deceleration.

1 · Permission and limits

Know exactly what you may do

You may

  • Maximum locomotor speed: Point out the run-in, 10 m flying split and deceleration finish. Walk the whole route before running. Start below sprint pace and increase speed smoothly through the run-in; do not blast the first three steps as a separate acceleration test.
  • During an authorised attempt, Through the flying zone, place each foot down and back close under the hips; keep the ankle firm without reaching forward. Keep the same action for several steps beyond the finish. Do not dip, lunge or look sideways at the timer.
  • Mark the build-up, fly and runoff zones, save both flying splits and record whether the learner completed the full braking zone under control.

Qualified help is required for

  • Review high-speed running history, present pain or asymmetry, environmental conditions and runoff space before approving a flying-speed exposure.
  • Choose the locomotor mode, run-in length, target intensity, timing zone, trial number, rest, surface and environmental limits.
  • Measure the same run-in for every pass, keep the timing display outside the runner's sightline, verify gate alignment and withhold another exposure until breathing, gait and readiness recover.

Never do this from the page alone

  • Attempt all-out speed after an inadequate run-in, on a crowded or slippery lane, or when the braking distance is shortened.
  • Do not lengthen the build-up, chase an extra fast pass or reduce the braking zone after seeing a favourable split.
  • Stop for pain, tightness, new asymmetry, loss of upright mechanics or inability to use the complete runoff without abrupt braking.

2 · Get ready

Gather what you need and check the starting conditions

What you need

  • A straight level lane with marked run-in, flying zone and long deceleration zone
  • Electronic timing gates or validated continuous-speed equipment
  • Cones or high-contrast ground marks
  • Secure footwear appropriate to the surface
  • A flying-speed record with locomotor mode, run-in length, gate spacing, surface, wind, footwear, entry and exit split, validity, symptoms and runoff outcome.

Before you start

  • Inspect the full lane, including the space beyond the finish gate.
  • Confirm run-in and flying-zone distances, wind or indoor conditions and the exact timing method.
  • Report recent hamstring, calf, Achilles or back symptoms and any long break from high-speed running.
  • Show the learner where to build speed, where the timed fly begins and where braking is allowed. Ask them to point to all three zones correctly before the first run-through.
  • Build speed in stages and rehearse arriving tall through the fly zone while continuing past the last gate; none of these preparatory runs is a maximum trial.

3 · The method

Follow these steps in order

  1. Survey the build, fly and runoff

    Walk from the rolling approach mark through the 30 m build, both 10 m fly sectors and the final runoff cone. Identify where upright fast running begins and where easing down is permitted.

    Why: A maximum-velocity pass needs enough approach to organise speed and much more space after measurement to reduce it safely.

    Check: The learner can point to approach, fly entry, fly midpoint, fly exit and full-stop boundary.

  2. Choose a rolling approach rhythm

    Enter the build from relaxed movement, then increase cadence and amplitude in planned stages. Do not imitate a crouched race start or attack the first steps.

    Why: A repeatable rolling approach reduces variation unrelated to upright velocity.

    Check: The 30 m build uses the same check marks and no abrupt early burst.

  3. Finish rising before fly entry

    By the last build marker, bring the torso upright with the pelvis tall and head quiet. Direct attention down the corridor rather than toward a sensor.

    Why: The fly zone is intended to sample upright locomotion, not the transition out of projection.

    Check: Side view shows stable torso height before the first timing beam.

  4. Cycle down beneath the pelvis

    Through the entry half, lift and recover the leg, then drive the foot down near the body's vertical line. Let stride length emerge from speed; never cast the shin forward.

    Why: A forward cast creates braking and often a visible backside recovery pattern.

    Check: Contacts occur close beneath the pelvis with no conspicuous heel-first reach.

  5. Preserve rhythm through the midpoint

    Cross the middle sensor without changing expression, arm sweep or contact timing. Keep hands loose, jaw soft and shoulders quiet while cadence remains brisk.

    Why: Many athletes strain at a landmark and lose velocity in the exit half.

    Check: Video and sector clocks show no midpoint lunge, lateral drift or sudden cadence disruption.

  6. Hold the exit half, not your breath

    Continue the same upright pattern across the second 10 m. If tightness or asymmetry appears, abandon the speed target and move into a gradual safe runoff.

    Why: Exit-half maintenance is useful only while movement remains organised and symptom-free.

    Check: Exit velocity stays within the coach's maintenance band and breathing remains unforced.

  7. Ignore the final clock

    Look beyond the last beam and continue fast for the provider-marked buffer steps. Do not dip, glance sideways or prepare a stopping plant.

    Why: Anticipating the sensor causes premature deceleration and contaminates the exit split.

    Check: The last beam is crossed in normal upright rhythm without a finish gesture.

  8. Bleed speed across the runoff

    After the buffer, reduce cadence gradually, allow shorter steps and remain on the straight corridor until walking. Turn only beyond the full-stop boundary.

    Why: A sharp plant or high-speed turn adds an unnecessary eccentric braking event.

    Check: The learner reaches a walk within the runoff without skid, cut, stumble or lane exit.

  9. Calculate maintenance before ranking

    Convert each 10 m sector to metres per second and divide exit velocity by entry velocity. Validate upright mechanics and environment before choosing the best pass.

    Why: The fastest entry half may produce a poor complete fly exposure if velocity collapses afterward.

    Check: The report shows entry velocity, exit velocity, maintenance percentage, wind or indoor status and technical validity.

4 · Worked example

See the whole method used once

Scenario

A trained runner uses an indoor straight with a rolling 30 m build, two consecutive 10 m fly sectors, a short buffer and a 35 m runoff.

Walkthrough

  1. The coach verifies sensor spacing, marks three approach checkpoints and records still indoor conditions before the high-speed warm-up.
  2. Pass A covers the entry half in 1.09 s and the exit half in 1.16 s: about 9.17 then 8.62 m/s, or roughly 94% maintenance; video shows straining at midpoint.
  3. After full recovery, Pass B records 1.12 s and 1.13 s: about 8.93 then 8.85 m/s, or roughly 99% maintenance, with quiet shoulders and contacts beneath the pelvis.
  4. Pass C is not requested because the planned exposure is complete; the learner does not chase Pass A's faster entry value.
  5. Both authorised passes continue beyond the last beam and end as a walk inside the 35 m runoff.
  6. The report selects Pass B as the cleaner maximum-velocity sample and retains Pass A as evidence of entry-speed fade.

Result

Pass B provides a valid 8.93 m/s entry and 8.85 m/s exit with approximately 99% maintenance in this indoor fly configuration. It does not measure departure acceleration or justify more all-out running.

5 · Right and wrong

Compare correct or safer execution with the common wrong version

Right and wrong comparison
MomentRight / saferWrong / riskierWhy it matters
Using the build-upIncrease rhythm through the same 30 m checkpoints and arrive upright before fly entry.Explode from a crouch and reach full effort in the opening metres.That substitutes a start test for a repeatable rolling approach.
Foot recovery at upright speedRecover compactly and strike down near the pelvis line.Throw the shin forward to manufacture stride length.Casting ahead creates a braking contact and disrupts fast cyclic action.
Crossing the midpointKeep face, hands and shoulders quiet while preserving cadence.Clench, lunge or surge because a sensor is visible.Landmark tension can create a fast entry followed by an exit-half fade.
Selecting the best passPrefer a valid, technically organised pass with strong velocity maintenance.Rank only the quickest entry 10 m despite a large second-half loss.Maximum-velocity execution includes sustaining the fly zone, not touching one early peak.
Leaving the fly zoneMaintain rhythm beyond the last beam before gradually easing down.Plant, dip or look at the clock as soon as the exit sensor arrives.Finish anticipation corrupts the exit value and increases sudden braking demand.
Deciding on another exposureStop at the pre-authorised count after a clean pass.Add repetitions until the display shows a personal record.Extra maximum-velocity contacts increase load while fatigue can hide emerging asymmetry.

6 · Common mistakes

Spot the error and apply the correction

Common mistakes and corrections
MistakeFix
The athlete begins each build-up at a different approach pace.Use the same rolling entry and three approach checkpoints before comparing fly sectors.
Upright posture is still changing at the first sensor.Lengthen or reorganise the provider-controlled build rather than forcing more effort inside the fly zone.
The lower leg casts ahead in pursuit of a longer stride.Return to a submaximal upright rehearsal and cue compact recovery followed by a downward strike.
A fast first half hides a clear second-half fade.Convert and display both velocities plus the exit-to-entry maintenance percentage.
The runner tightens at the midpoint marker.Move attention beyond fly exit and rehearse crossing all sensors without a gesture.
The runoff is shortened to fit another repetition.Keep the full marked stopping distance; remove the repetition, never the deceleration space.

7 · Practice

Turn the steps into a usable skill

First session

  1. Walk the entire rolling approach, 30 m build, entry half, exit half, buffer and 35 m runoff while naming each boundary.
  2. Rehearse two progressive builds below high speed, using approach checkpoints and finishing upright before fly entry.
  3. Perform one submaximal fly pass to practise compact leg recovery, quiet midpoint crossing and a complete runoff.
  4. After coach-timed recovery, complete no more than two authorised high-speed passes with both sector clocks active.
  5. Calculate entry velocity, exit velocity and maintenance percentage before discussing the fastest display.
  6. End the exposure after the planned clean pass and review one upright video landmark rather than adding another run.

Repeat plan

A later high-speed session repeats approach check marks, sensor geometry, footwear, surface and environmental record. The coach may progress approach rhythm or target velocity only after both fly halves remain technically organised and the runoff stays effortless. Assisted towing, overspeed devices, additional passes and weekly loading are separate provider decisions, never learner-selected extensions.

Progress when

  • The rolling approach reaches upright posture at the same pre-entry location on consecutive passes.
  • Entry and exit velocities are repeatable and maintenance remains inside the provider's band.
  • Compact recovery, down-under contact and quiet midpoint rhythm persist as velocity rises.
  • The learner completes the buffer and long runoff without symptom, stumble or abrupt braking.

Do not progress when

  • A faster entry sector produces growing exit fade, reach or upper-body strain.
  • Wind, sensor spacing, approach marks, surface or footwear no longer match the comparison setup.
  • Cadence becomes irregular or one side visibly shortens during upright running.
  • Hamstring, calf, Achilles, hip or back tightness, pain, a pop or reduced runoff control appears.

8 · Check the result

Measure what changed

Maximum-velocity fly profile: entry-half velocity, exit-half velocity and exit-to-entry maintenance percentage after a fixed rolling build

How: Fix rolling entry, build checkpoints, consecutive 10 m sectors, sensor model, surface, footwear and indoor or wind record. Convert each valid sector time to velocity and retain technical video notes.

Good result: Two passes reproduce upright entry and sector velocities within tolerance, with strong second-half maintenance, organised contacts and safe runoff.

This does not prove: A fly profile does not establish fixed-start acceleration, reaction ability, curved or change-of-direction speed, competition readiness or safety elsewhere.
