Run Faster: The #1 Speed Secret Most Runners Get Wrong

Main summary

Educational

Main ideas / lessons

  • Race speed depends less on how high you lift your knees and more on what happens in the milliseconds after your foot contacts the ground.
  • Elite sprinters achieve very short ground contact time (GCT)—their foot hits and leaves the track so quickly that it may not be visible in normal viewing speed.
  • Many common sprint drills can be helpful for coordination, but if you spend too much time doing them in a slow, rhythmic way, they can reinforce “soft” footwork/patterns that limit speed.
  • To improve sprinting speed, you should train for:
    • Short ground contact time
    • Stiffness in the ankles/hips and a rigid, “spring-like” lower leg
    • Proper use of the body’s stretch-shortening cycle via tendons (especially the Achilles), not just muscle strength.
  • Speed is framed as a learnable skill: intentional rehearsal of fast mechanics makes sprinting feel “automatic” at track meets.

Key concepts and quantitative claim

  • Ground contact time definition: how long the foot stays in contact with the ground each stride.
  • Typical ranges (as stated):
    • Recreational runner: ~250–300 milliseconds
    • Top-speed sprinter: ~80–90 milliseconds
    • Top humans are described as being “a tenth of a second” or less.

Why ground contact time matters (as explained)

  • Sprinting is not about “pushing the ground for a long time.”
  • Instead, it’s about applying force quickly in a short window:
    • Legs should be under the body
    • The runner should hit the ground fast and leave fast
  • Longer contact is described as slower, energy-wasting, “leaky” motion.
  • Analogy:
    • A ball with proper pressure bounces quickly
    • An under-inflated ball rebounds sluggishly
    • Your body should behave similarly by minimizing wasted absorption.

Core idea: the goal is fast force application + fast release, not prolonged contact.

Methodology / training instructions

1) Prioritize ground contact mechanics over knee height

  • Don’t over-focus on “lift knees high.”
  • Use cues that emphasize fast foot strike and rapid departure, such as:
    • “Punch in the ground, get off fast.”
    • “Quick ground contact—hit the ground quicker.”
  • Mechanical targets mentioned:
    • Stiff ankles
    • Stiff hips
    • Foot landing under the center of mass
    • Push away quickly after contact
    • Keep the body tight/compact

2) Use drills strategically (primer vs speed-specific)

  • Recognize drill roles:
    • Primer drills for warm-ups/motor skills (acceptable), including:
      • A skips
      • Marches
      • High knees
    • Problem: if these are done only in a slow, dragging way, they can slow down speed development.
  • For speed development (especially on speed days), warm-ups and drills should become more specific and faster, such as:
    • Bounces
    • Power skips
    • Cycling drills
    • Drills that emphasize quick ground contact
  • Drill mindset:
    • Speed requires intentionality
    • Rehearse mechanics repeatedly so they become second nature

3) Drills recommended to improve ground contact time (examples)

  • Bent knee bound (called “underrated” and “number one”)
  • High knees (stated as helpful for GCT too)
  • Single-leg cycling drills
  • Pogo hops (front/back/side/side variants mentioned)
  • Bent knee bounce and straight leg bounce
  • Straight leg bounds
  • Power skips

General rule for pogo/hopping work:

  • Vary intent:
    • sometimes land and stop
    • sometimes be explosive
    • sometimes stay very bouncy
  • Pogo work is described as reinforcing being “quick on the ground.”

4) Train ankle/tendon stiffness via the stretch-shortening cycle (“tendon secret”)

  • Main claim: the key spring behavior is tendon stiffness, not simply muscle.
  • Achilles tendon is highlighted as critical:
    • If weak, “springs are weak,” limiting sprinting speed.
  • Training goal:
    • Strengthen and utilize the tendon’s stretch → snapback → force return
  • Important execution idea:
    • Do not absorb/flatland the energy; use it to launch forward

Suggested training styles (as stated):

  • Time-under-tension (iso stuff) to build capacity
  • Bouncy/reactive work, including:
    • Pogo hops
    • Hurdle hops
    • Resisted sprints
    • Weighted bouncy/strength versions

Frequency note:

  • Bouncy/reactive work should be done every other day (not necessarily daily), per the guidance given.

5) Practical cues and execution rules

  • Athletes should sound/feel:
    • light and quick, not heavy and big
  • Landing goal:
    • “hot lava” metaphor—lift and place quickly (“pop”)
  • Efficiency:
    • Don’t be lazy with drills; be quick and efficient

Overall takeaway / conclusion

  • Speed is not about maximizing knee lift height.
  • It comes from short, stiff, fast ground contact and using ankle/tendon stiffness to avoid wasted energy.
  • Add the emphasized mechanics and drills into training weekly, focusing on what your foot does at ground contact to improve sprint times.
