Choosing a first trail race: climb, kit and pace
Trail racing uses the same legs as road racing and almost none of the same assumptions. Pace stops meaning anything, the distance on the entry page is a rough guide, and the finish time depends more on the ground than on fitness.
Read the elevation, not the distance
A flat 20 km on forest paths and a 20 km with 1000 metres of climbing are different sports. For a first trail race, the useful number is elevation gain per kilometre. As a rough guide, under about 20 metres is runnable, around 40 is a hard day with walking in it, and above that the race becomes a hike with running sections.
Organisers publish the profile and often a cut-off at each checkpoint. Both matter more than the headline distance.
Walking is part of the plan
Experienced trail runners walk the steep climbs deliberately, hands on thighs, and run the flats and descents. Treating every climb as something to be run is the fastest way to arrive at halfway with nothing left. Practising the walk is a session in itself.
Descending is the other half, and it is the part that leaves road runners unable to walk down stairs for three days. Much of the damage comes from braking forces rather than general fatigue, which is why eccentric training protects the legs on descents.
Mandatory kit is not a suggestion
Most mountain races publish a required kit list and check it at registration or at random on course. A missing item means a penalty or a refused start, and the list exists because weather at altitude changes faster than the race does.
- Waterproof jacket with taped seams, hood included.
- Phone, charged, with the organiser’s number saved.
- Water capacity stated by the organiser, usually a litre or more.
- Food for the full time between aid stations.
- Emergency blanket and whistle.
Shoes and feet
Grip matters more than cushioning on anything steep or wet, and a shoe that works on dry forest paths can be useless on mud. Feet also swell over hours, so trail shoes are usually bought half a size up from road shoes, and tested on a long run before the race rather than during it.
Whatever the race, the organiser’s own page has the profile, the checkpoint cut-offs and the kit list, so read all three before paying the entry.
