Field note 01 · Desierto de los Leones

Before the city wakes,
the forest does.

Desierto de los Leones at first light — a local way into Mexico City, one unhurried kilometre at a time.

Mexico City · 16 km · +720 m

At 6:10, the city still feels far away. The first thing you notice is not the elevation. It is the quiet: wet earth, pine needles, the small sound of shoes finding the path.

A running morning is not a checklist of highlights. It is an invitation to borrow the rhythm of a place.

Not a route to collect. A place to enter.

From the forest edge, the trail rises without asking permission. The ground is soft in places, rocky in others. You settle into the honest work of climbing; there is no need to perform for anyone.

At 2,800 metres the air gives back less than you expect. Runners who arrive from sea level and treat this as an ordinary sixteen kilometres learn the difference somewhere in the second hour. The correction is not fitness. It is patience.

The right local run makes a new city feel less like an itinerary and more like a memory.

07:38 — the first viewpoint

You reach a clearing as cloud moves through the lower trees. Someone shares a piece of fruit. You learn the name of a distant ridge in Spanish. A guidebook could tell you the altitude; it cannot give you this pause.

Then the descent, which is its own argument: pine litter over hard-packed dirt, fast if you trust it, punishing if you fight it. By the time the forest opens back toward the road, the city has woken up without you, and that is the whole point of leaving early.

What to know before you go

The park is open year round. The dry season, roughly November to April, gives the most reliable footing; the rains arrive in the afternoons of summer and the descent turns slick. Go at first light, carry your own water, and treat the altitude as the main event rather than a footnote.
