My 1st Spartan DEKA Fit experience

Movement is a privilege. This Saturday, I put mine to the test once again at the country’s inaugural Spartan DEKA Fit race.

DEKA Fit is a standardized indoor fitness race. Ten 500-meter runs alternate with ten functional training zones, making the whole event one continuous test of endurance, strength, and movement efficiency. Every run taxes your pacing and aerobic control before you enter a station that asks something completely different from your body.

The first half builds the burn. The SkiErg demands upper-body power and rhythm. Dead ball wall squats load the legs. Box jump-overs require explosiveness and coordination just as fatigue begins to accumulate. The RowErg brings back the pull, and med ball sit-ups test the core while your breathing is already ragged.

The second half is about grip and grit. Farmer’s carries test total-body tension and posture. The BikeErg drives the heart rate up. Dead ball carries ask for brute strength and stability while moving a load. Burpee broad jumps strip everything down to explosive power and mental control.

Then come the wall balls: high reps, full body, rewarding those who can pace, aim, and hold form when exhausted.

Unlike obstacle course racing, DEKA has no surprise obstacles. Every course is the same, which makes it a true benchmark. The question it asks is simple: how well can your body keep working across different movements as fatigue piles up.

Why put myself through this?

For years, my fitness revolved around running and hiking. I have come to believe that cardio alone is not enough, especially as we age. Strength and conditioning matter more with every passing year.

In her book Forever Strong: A New Science-Based Strategy for Aging Well, Dr. Gabrielle Lyon calls skeletal muscle “the organ of longevity.” Muscle is not just for movement or looks. It plays a central role in how long, and how well, we live.

But, according to Dr. Lyon, having muscle is not the whole story. It has to be usable under real-world demands. That is what functional fitness means: the ability to carry, hinge, push, pull, rotate, and brace, and to produce force again and again without breaking down. It is not lifting a weight once. It is sustaining effort while tired, off-balance or carrying a load. Functional fitness turns muscle from a biological asset into a longevity tool you can actually use.

This matters most when we consider the biggest risks of aging: falls and frailty. Loss of strength and coordination raises the risk of falling, and a single fall can lead to hospitalization and rapid decline. Functional training builds balance, reaction time, joint stability, and the ability to absorb force. The goal is not just to live longer, but to avoid breaking down while living.

The way I see it, there is a hierarchy. Muscle mass is the foundation. Strength is the ability to produce force. Functional capacity is strength you can use in real conditions. Endurance is the support system. Many endurance athletes, myself included until recently, turn this order upside down.

This is why I have turned to hybrid training. I still value a strong cardiovascular engine. But high-volume endurance training on its own does little to build muscle and can even work against it. Without strength work, years of mileage can quietly lead toward frailty.

Before the race, I asked ChatGPT to project my DEKA Fit time based on my latest HYROX result. It predicted from 1:15 to 1:22, with an outside chance of about 1:12.

I finished in 1:02. Not too shabby.
