Autumn brings with it the arrival of the eagerly anticipated London marathon ballot results and subsequently a lot of marathon excitement in the UK. There’s no question that running a marathon is an incredible achievement and large scale events like London, Manchester and Brighton attract thousands of runners every year.
For runners seeking adventure beyond the classic 26.2-mile road marathon, the UK offers thrilling alternatives that test endurance, teamwork, and mental resilience. From muddy obstacle courses to mountain treks, these events provide unforgettable challenges while catering to diverse fitness goals. Below, we explore five standout options, complete with training insights, event specifics, and tips for success.
Sponsored by Brooks Running, HellRunner is a trail-running series notorious for its extreme terrain and unpredictable conditions. Unlike road marathons, participants navigate steep hills, deep bogs, and forest trails, often in harsh weather. The event’s slogan—“Run if you dare”—sets the tone for a race designed to push runners beyond their limits. The event is famous for its unpredictable terrain, which includes steep hills, deep bogs, and dense forests, often in challenging weather conditions.
Preparing for HellRunner requires a different approach than training for a road marathon. You’ll need to build strength in your quads and calves to handle the steep ascents and descents, as well as improve your balance and agility for uneven terrain. Hill repeats, trail runs, and strength training sessions should be staples in your training plan. Practising running in muddy or wet conditions can also help you adapt to the unpredictable environment on race day.

Wings for Life World Run
The Wings for Life World Run is a truly unique event that combines running with a global charity mission. Unlike traditional races, there is no fixed finish line. Instead, a “catcher car” starts 30 minutes after the runners and gradually increases its speed, overtaking participants one by one. The event is held simultaneously in multiple countries, with all proceeds going to spinal cord research.
Because the distance is unpredictable—determined by a “catcher car” that overtakes runners—your training should focus on building endurance and speed. Incorporate long, steady runs into your routine, but also practise running at different paces to prepare for the possibility of being caught early or late in the race. Interval training and tempo runs will help you improve your speed and stamina. Don’t forget to practise your nutrition and hydration strategy, as you might be out on the course for longer than expected. Energy gels and hydration packs are a good idea for race day.

Three Peaks Challenge
The Three Peaks Challenge involves climbing the highest peaks in Scotland, England, and Wales—Ben Nevis, Scafell Pike, and Snowdon—within 24 hours. The total walking distance is around 23 miles, with nearly 3,000 metres of ascent. The route takes you through some of the most beautiful landscapes in the UK, with stunning views from each summit. The challenge is both physical and mental, requiring teamwork, good planning, and the ability to keep going when the going gets tough.
Preparing for the Three Peaks Challenge requires a combination of endurance, strength, and mental resilience. Start by building your hiking endurance with long walks, gradually increasing the distance and intensity. Try to hike with a weighted pack to simulate the weight you’ll carry during the challenge. Stair climbing or hill repeats are excellent substitutes if you don’t have access to mountains. Cross-training with running, cycling, or swimming will help you maintain your overall fitness. Practise navigation skills and learn to read a map and compass, as the weather in the mountains can change quickly. Sturdy hiking boots, moisture-wicking socks, and lightweight rain gear are essential for race day.
Why Choose the Three Peaks Challenge?
If you love the great outdoors and want a break from running, the Three Peaks Challenge is a fantastic alternative. It’s a test of stamina, teamwork, and mental resilience, and it’s often completed as a group, making it a great bonding experience. The sense of achievement at the end is immense, and the memories of climbing each peak and enjoying the views will stay with you long after the challenge is over. It’s perfect for anyone who wants to explore the UK’s wild landscapes and push their limits.
Red Bull 400
If you’re searching for a running event that’s as much about raw power and mental grit as it is about speed, look no further than the Red Bull 400. This unique race turns the world of endurance on its head—literally. Instead of long distances on flat terrain, you’re challenged to sprint 400 meters straight up a massive ski jump, battling gravity, lactic acid, and your own willpower. The Red Bull 400 is a global phenomenon, attracting everyone from elite athletes to weekend warriors eager to test their limits in one of the most intense and exhilarating running experiences out there.
Preparing for the Red Bull 400 means training your body for a short, explosive effort that demands both strength and endurance. Unlike traditional running events, this race is more akin to climbing than jogging, especially as the incline ramps up to over 35 degrees. Focus on hill sprints, stair climbs, and strength exercises like squat jumps, landmine squats, and bear crawls to build the leg and core power you’ll need. Upper body strength is also important, as you may find yourself using your arms to pull yourself up the steepest sections. Interval training—such as repeating 200-meter uphill sprints at 85% effort—will help you adapt to the unique demands of the course. Don’t forget to include plenty of recovery, as these workouts are tough on the muscles and joints.
Why Try Red Bull 400?
The Red Bull 400 is for anyone who wants to push their limits, try something completely different, and join a global community of like-minded adventurers. It’s not just about running—it’s about conquering a unique, unforgettable challenge in a spectacular setting. The event is open to all skill levels, so whether you’re a seasoned athlete or a first-timer, you’ll find a supportive, high-energy atmosphere that celebrates effort and achievement. Finishing the Red Bull 400 gives you bragging rights for life and a story you’ll never forget—because when you sprint up a ski jump, you’re not just running a race, you’re making history.
