Hey there,

I’ve been an S&C coach in professional and Olympic sport for 30 years, so I know your time is valuable. My aim here is simple — to give you something valuable in return for just a few minutes of your time.

Why I Built SpeedSig

Over the last decade, while studying running in field sports for my PhD, I collected thousands of samples from professional athletes. What I discovered was a blind spot in our testing and monitoring framework.

We track isometric strength, hops, jumps, distances, and speeds run…
But what we don’t measure is how our athletes actually run.

When I started analyzing those running patterns and linking them to both performance and injury, my priorities as a coach changed. That insight became the foundation for SpeedSig — a simple, field-based system to quantify the kinetics, kinematics, and stability of running at all speeds using the GPS units you already deploy.

SpeedSig was built by a coach, for coaches.

The Problem With Early Versions

Here’s the truth: biomechanics can feel overwhelming.

There are so many interrelated variables — and they shift with speed.
Early versions of SpeedSig were powerful but dense. One EPL club said to me, **“SpeedSig is going to be great… we just don’t know how.”**
And they were right.
That feedback was a turning point. We needed to make SpeedSig faster, simpler, and easier to act on.

Introducing SpeedSig 3.0

Today, I’m excited to announce the upcoming release of SpeedSig 3.0 — rebuilt from the ground up based on how coaches actually make decisions.

Here’s what’s new:

✅ Simplified Group & Individual Screens
Clean card and list layouts that show only the five most impactful variables — the ones that drive speed variability.

✅ Colour-Based Analytics
Each variable is coded green, red, or white based on performance, asymmetry, and trend. This clarity means your eyes are instantly drawn to what matters most.

✅ Speed-Specific Analysis
View mechanical patterns across low, moderate, and high speeds — uniquely available in SpeedSig.

✅ Deep Dive & Integrated Education
Click a pattern and you’ll see what it means, how to coach it, and which drills or cues to target. Strength & conditioning, sports science, and medical teams can now speak the same language.

✅ Tech Stack Integration
SpeedSig 3.0 fits alongside the systems you already trust — force plates, isometric tests, eccentric hamstring data, and GPS. It doesn’t replace anything; it connects everything.

The Tech Stack Problem

After three decades in this game, I’ve seen the rise of our current performance tech stack. I was there for the first day of:

GPS tracking
Eccentric hamstring testing
Commercialized dual force plates

Spend enough time with these systems — and make enough mistakes — and you eventually find the gaps. That’s the problem SpeedSig was built to solve.

I wrote about this recently in our blog:
👉 Gym Data vs Running Biomechanics

SpeedSig 3.0 cuts through the noise, fills the gaps, and shows how to integrate every piece of your tech stack into one operational system.

Why It Matters

Because mechanics are the engine of our sport.

When your staff can see the patterns and coach them efficiently, change happens faster.
You get cleaner mechanics, more repeatable outputs in rehab, clearer go/no-go decisions — and athletes running better, later in the game.

Most importantly, you get one language across departments.

SpeedSig was built by a coach, to answer the questions I know coaches are asking.
SpeedSig 3.0 makes those answers easier to see — and easier to act on.
