Climb high and come down safely: Here’s how to specifically train for elevation gain in trail running.
Trail running begins where the pavement ends. And it only gets truly exciting with added elevation gain. Whether it’s a steep climb or a technical downhill: if you want to succeed off-road, you should focus on specific uphill and downhill trainings. While climbing sends your heart rate soaring, steep descents challenge your coordination, muscles, and technique.
The steeper the climb, the more your stride shifts to the forefoot and the shorter your steps become. It’s important to keep your hips "high" (avoid a seated posture), which improves your center of gravity. Still, don’t lean your upper body too far forward, as this can impair breathing. Even on tough, steep sections, keep your gaze forward rather than directly down at your feet. Active arm movement is crucial as your arms set the rhythm and support your running motion. Taking small steps helps you stay less winded. Running in switchbacks also saves energy.
The worst muscle soreness in trail running usually comes from the downhills, not the climbs. On fast, flowing descents, try to keep your stride low and avoid excessive jumping to reduce strain on tendons and joints. Despite the slope, aim to land softly and dynamically on the midfoot or forefoot rather than harshly on the heels. Spread arms and strong core tension help maintain balance.
So what does specific hill training actually look like? Whether you’re a hill or flat runner, most of your training should be in the aerobic endurance zone — i.e., at a steady, easy heart rate. If your season goal includes a mountain run, you can continue with most of your regular runs. Like every runner, mountain runners mainly train their base endurance. And that’s best developed on flat terrain. In other words: if you want to be fast in uphills, you also need to train a lot in the valley.
There are, however, some specific training variations tailored for future mountain goats. These should be adapted based on your season goals and the course profile. It’s important to differentiate between mountain runs that end at the summit and trail runs that include significant elevation gain but also lots of descending. For runs with downhill sections, downhill training must be done in advance, as the eccentric muscle load from descending can lead to serious soreness if not practiced regularly.
