How the free tier works: one Try It Out preview gives you the Watch-Ready crash course (tool 1) of every sport — not just this one — so you can sample the whole platform. The Season Pass then opens all eight tools of every module, the cross-sport toolkit, and your full SpectatorIQ.

The field guide

What to know before the next one

Running off-road, usually on mountain terrain, from short technical races to 100-mile ultras with tens of thousands of metres of climbing. Pace is meaningless here; what matters is climbing, descending and keeping going.

The events that matter

UTMB Mont-Blanc — Every August. Around 170km with 10,000 metres of climbing, circling Mont Blanc. The sport's most prestigious race.
Western States 100 — Every June. The oldest 100-mile trail race, in California.
World Mountain and Trail Running Championships — Every two years. The formal world titles across short and long trail.
Ultra-trail Cape Town and the Otter African Trail Run — Every year. South Africa's two internationally known trail events.

Five things to watch the first time

Watch the climbing rate rather than the pace. On a steep climb, walking fast is often faster than running.
Watch the descents. Races are lost by runners who cannot descend, and quads give out long before lungs do.
Watch the aid stations in ultras. What a runner eats and how long they stop decides the last 30 kilometres.
Watch the cut-offs at each checkpoint. In long ultras most of the field is racing those, not the leaders.

Where it is played

France, Spain, Italy, the United States, Britain, Switzerland, Japan, South Africa and across the Nordic countries.

Who plays it, and from what age

The sport skews older than road running — ultra performance peaks surprisingly late, often in the thirties and forties. Entry-level trail races are typically 5 to 15 kilometres.

Who sets the standard

France, Spain and the United States lead the ultra scene; Uganda, Kenya and Ethiopia are increasingly strong at shorter mountain distances.

The South African angle

South Africa's terrain makes it a natural trail nation. The Otter African Trail Run on the Garden Route is regarded as one of the world's great trail races, Ultra-trail Cape Town draws international fields, and Table Mountain is one of the finest urban trail networks anywhere.

Words you will hear

vert — Vertical metres of climbing. The real measure of a trail course.
an aid station — A checkpoint with food, water and often a drop bag.
a DNF — Did not finish. Common and not shameful in ultras.
power hiking — Deliberately walking a climb fast rather than running it.
