Trail running training plan: get fitter and faster in just four weeks
Our off-road trail running training plan will help you get fitter, faster and stronger in just half an hour three times a week
Swap tarmac for the trail with our four-week trail running training plan – and you could melt fat and burn 10% more calories than normal.
Trail running has exploded in popularity in recent years, particularly during lockdown when people craved ways to keep fit and connect with nature.
And, considering the body benefits you can get just by heading off the beaten track, it's not surprising that so many people have invested in a pair of the best trail running shoes and headed into the great outdoors.
The constant challenge of different terrains, gradients and environments – whether you’re running through grassy fields, on forest paths, over rocky hills or beaches – not only helps build fitness, but also bodily strength.
'Running on uneven ground forces us to engage our core and upper leg muscles more than normal,’ explains personal trainer Scott Laidler. ‘It helps develop stronger muscles in our lower legs, ankles and feet, while also targeting our ligaments and connective tissues, which helps improve our power and drive, and over time reduces our risk of impact injury.’
It’s a great cardio workout too. There’s no chance of relaxing into a predictable jogging pattern. With sudden shifts in gradients and the potential en-route obstacle, you’ll ramp your heart rate up in no time and break a serious sweat.
Still not convinced? ‘Getting outdoors and into nature helps reduce stress levels, often associated with urban environments,’ says Laidler. We’re sold!

Four-week trail running training plan
Laidler has created a four-week trail running training plan that is ideal for beginners or anyone wanting to improve their current performance.
It includes tempo runs to improve fitness, endurance runs to increase muscular endurance and strength, and Fartlek (unpredictable, varied pace) runs to ramp up speed.
Laidler's top tip? Take your eye off your running watch. ‘This isn’t your normal cardio training where you aim to complete a particular distance in a certain time,' he says. 'Take it slowly and pace yourself, as you don’t know what kind of obstacle will be around the corner.'
Staying safe is also important. Laidler recommends that new trail runners join a local group, which has assigned routes and leaders. Or if you are heading out alone? ‘Tell someone which route you’re going and when you’ll be back, and take your phone.’
