Dubai has never been shy about ambitious ideas. From indoor ski slopes in the desert to record-setting skyscrapers, the city has built a reputation for redefining what is possible. Now it is turning that ambition toward endurance sport with a proposal that has runners around the world paying attention: a 93-kilometer air-conditioned tunnel designed for running.

If built, it would be the longest climate-controlled running corridor ever attempted—an uninterrupted, weather-proof route stretching across large sections of the city.

Why This Matters to Runners

Dubai’s extreme climate is the driving force behind the proposal. For much of the year, outdoor running is limited to early mornings or late evenings, with daytime temperatures frequently exceeding 100°F (38°C) and high humidity compounding the stress on the body.

An enclosed, air-conditioned running tunnel would eliminate those constraints. Runners could train year-round, at any hour, without concern for heat illness, sun exposure, or traffic. For recreational runners, older athletes, and those new to the sport, that kind of consistency could be transformative.

Training Benefits—and Limitations

From a training standpoint, the advantages are clear:

• Stable temperatures

• Predictable, impact-friendly surfaces

• Long, uninterrupted distances

• A fully traffic-free environment

At the same time, running has always been shaped by the elements. Wind, hills, heat, and changing conditions are part of how runners adapt and improve. For competitive athletes, the tunnel would likely serve as a supplement, not a substitute—ideal for recovery runs, high-mileage days, or summer training, but not a replacement for real-world conditions.

What Would Something Like This Cost?

No official cost estimate has been released, but based on comparable large-scale urban infrastructure projects, a realistic figure can be narrowed to a much tighter range than early speculation suggests.

A purpose-built, enclosed running corridor with full climate control—without the complexity of deep metro tunneling—would likely cost between $120 million and $180 million per kilometer.

Applied to a 93-kilometer project, that places the total estimated cost in the range of:

$12 billion to $17 billion (USD)

That estimate includes structural construction, climate control and ventilation systems, lighting, safety infrastructure, and multiple access points—but assumes a design optimized specifically for runners rather than heavy transport use.

Sustainability Will Decide Its Legacy

Cooling nearly 100 kilometers of enclosed space in the desert raises obvious questions about energy use. Dubai officials have suggested renewable energy and advanced efficiency systems would be incorporated, though details remain limited.

Ultimately, the project’s long-term acceptance may hinge as much on sustainability as on ambition.

A Glimpse at the Future of Running Cities

Even if the full 93 kilometers never materialize, the concept itself reflects a broader shift: cities increasingly recognize running infrastructure as a public-health investment, not a luxury.

From protected running paths to car-free zones and illuminated night routes, urban design is evolving. Dubai’s proposal simply pushes that idea to its extreme.

Final Thoughts

A 93-kilometer air-conditioned running tunnel sounds futuristic—but so did many of Dubai’s previous projects before they became reality.

It won’t replace roads, trails, or the need to train in real conditions. But it could redefine what year-round running looks like in extreme climates—and open the sport to thousands who might otherwise never lace up.

For runners, that makes this idea worth watching closely.
