Why Aletheia

Runners Train Hard. But Most Never Train Smart.

Most runners only see what’s on the surface; pace, distance, and heart rate. But that’s not what causes injury or limits performance. Aletheia Run reveals the hidden forces that truly matter.
Running Blind

The Old Way

You log miles. You watch your pace. Maybe your heart rate too. But you’re still plateauing; or worse, getting injured. Traditional tools don’t show how your body moves or what’s breaking down.
Train Smarter with Force PORTRAIT Insights

The Aletheia Run Way

With just a lightweight sensor and our app, Aletheia Run analyzes the forces your body produces; step-by-step. You get clear, visual feedback that shows where you’re strong, where you’re unstable, and how to improve.

Efficiency

Efficiency measures how much energy you could be losing to excessive motion in your form. A lower efficiency score suggests that your form may be using more energy than necessary while a higher efficiency score suggests that you have a form with economical energy usage.

  • Maximize Your Energy Use – Reduce wasted movement and keep your energy focused on forward motion.
  • Improve Your Running Economy – A higher efficiency score means you’re running smoother and using less effort per step.
  • Refine Your Form – Identify areas like excessive arm swing or overstriding that could be costing you energy.

Variation

Variation measures how much your form changes from one stride to the next. A lower variation score suggests that you may have inconsistencies in your form while a higher variation score suggests that your form is consistent.

  • Find Your Rhythm – A consistent stride leads to better efficiency and lower injury risk.
  • Minimize Unnecessary Adjustments – Less variation means smoother, more predictable movement patterns.
  • Stay in Control – Detect inconsistencies in footstrike, cadence, or posture before they impact performance.

Impact

Impact measures the strength of the forces that your body experiences as you contact the ground. A lower impact score suggests that you are stressing your body by exposing it to large forces while a higher impact score suggests that you are mitigating the stress that your body experiences.

  • Protect Your Joints – Lower impact means less stress on your body with every step.
  • Absorb Force Efficiently – A controlled landing reduces excessive force traveling up your legs.
  • Optimize Ground Contact – Identify if you're landing too hard and adjust for a softer, more controlled stride.

Braking

Braking measures how much you decelerate while your feet are in contact with the ground. A lower braking score suggests that your form is causing you to lose energy by temporarily slowing yourself down with each stride while a higher braking score suggests that you have a smooth form that allows you to conserve energy.

  • Keep Your Momentum – Reduce sudden slowdowns that waste energy.
  • Smooth Transitions – A high braking score means less deceleration, leading to better endurance.
  • Land Efficiently – Minimize braking forces by keeping foot placement aligned with your center of mass.

Sway

Sway measures lateral (side-to-side) motion in your form. A lower sway score suggests that your form has excessive lateral motion while a higher sway score suggests that your motion is in alignment with the direction that you are running.

  • Run in a Straight Line – Reduce side-to-side movement that takes energy away from forward motion.
  • Improve Stability – A higher sway score means better core control and balance.
  • Stay Aligned – Detect excessive hip or torso motion that may be holding you back.

Endurance

Endurance measures how consistent your form is from the middle to the end of your session. A lower endurance score suggests that your form noticeably changes by the end of your run while a higher endurance score suggests that your form stays consistent through the end of your run. Endurance is only calculated when you are running for at least 9 consecutive intervals.

  • Maintain Your Form Longer – A high endurance score shows you’re keeping good posture and stride even as you fatigue.
  • Run Strong to the Finish – Identify when your form starts breaking down so you can push through effectively.
  • Improve Long-Term Performance – Build stamina by recognizing how fatigue affects your running mechanics.

Warmup

Warmup measures how consistent your form is from the start to the middle of your session. A lower warmup score suggests that your form noticeably changes by the middle

  • Ease Into Your Stride – A proper warmup leads to smoother, more efficient movement.
  • Reduce Injury Risk – Gradually improving form early on prepares your body for the full run.
  • Find Your Optimal State Faster – A high warmup score means your mechanics stabilize quickly, leading to better runs.

Injury Diagnostics

Prevent injuries before they happen with in-depth diagnostics that highlight potential risk factors and guide corrective actions.

Hip Mobility

Hip mobility measures the range of motion in your hips to ensure fluid and efficient running. Improving hip mobility can enhance your stride length and running efficiency, reducing the risk of injury.

  • Measures hip's backward movement (hip extension).
  • Limited hip extension can cause low back and hamstring injuries.
  • Keep the hip mobility scale low; yellow or red means more hip exercises are needed.

Hip Stability

Hip stability evaluates the control and strength of your hips to maintain proper alignment. Enhanced hip stability helps prevent injuries and improves overall running form.

  • Strength and control to keep pelvis steady during side-to-side movement.
  • Reduces risk of injuries like low back pain and IT band syndrome.
  • Low hip stability scale is good; yellow or red suggests the need for strength exercises.

Portrait Symmetry

Your Portrait Symmetry Score helps measure how evenly your left and right legs move during each step. A higher score means your motion is more balanced. Your score is based on three types of symmetry:

  • Forward Symmetry – Compares how much force your left and right leg generate as they push forward.
  • Vertical Symmetry – Compares how evenly your legs move up and down.
  • Lateral Symmetry – Compares side-to-side movement between your left and right leg.

FAQs

You got questions?
We have answers.

What makes Aletheia different from a Garmin or Whoop?

Most wearables track pace or heart rate. We track the quality of your movement. Nothing else on the market visualizes force like this.

What devices does the app work with?

iPhone now. Android and Apple Watch coming soon.

What if I don’t like it?

Cancel any time during the trial — no charge. After that, cancel your annual membership at any time.

Do I need to run a certain way for it to work?

Nope. Aletheia Run works on roads, trails, treadmills and tracks.

Is this for beginners or pros?

Either. This is meant for all levels.
