It's long enough to be a true test of fitness, stamina, pacing, form and mental strength but short enough to be within reach of anyone willing to train consistently for a couple of months.

Can you run a half marathon without training?
Can you run a half marathon without training?
While it is physically possible to run a half marathon without training, we really wouldn’t recommend it. From both an enjoyment and health perspective, training correctly before embarking on a half marathon is going to lead you to have a much better experience.
Running a half marathon requires a significant level of endurance, stamina, and physical fitness. Without proper training, you are more likely to experience discomfort, fatigue, and the risk of injuring yourself is much higher. Training allows your body to adapt, get stronger and build stamina - everything you’ll need to enjoy the challenge of a half marathon race. Diet is also important, for more info take a look at our guide on what to eat before a half marathon.

If I can run a 10k, can I run a half marathon?
If you can successfully run a 10K (which is approximately 6.2 miles), you can definitely work your way up to running a half marathon. It is roughly twice the distance, so naturally, you’ll need to enhance the stamina and endurance you’ll have already built in running 10 kilometres. Following a structured training plan that allows for rest and increasing distance incrementally is the safest way to build up to the full 13.1 miles.
What types of Half Marathon are there?
What types of Half Marathon are there?
There are two main types of Half Marathon events to participate in: Road Races and Trail Runs.
Road Half Marathons are the most traditional and popular type of half marathon. It takes place on paved roads or streets, typically in city or suburban areas with well-planned routes and water stations. Choose from a range of mass-participation Half Marathon events in London, Manchester, Birmingham and many more big cities and towns across the UK. These types of races also often have fantastic routes that pass iconic landmarks and tend to have buzzing crowds cheering runners on.
Trail Half Marathons are held on off-road trails in woodland settings or on hiking trails. They deliver a more scenic and natural experience but tend to be much more demanding due to the variety of terrain and uneven surfaces.
What is a respectable half marathon time for a beginner?
What is a respectable half marathon time for a beginner?
Around 2 hours 15 minutes to 2 hours 45 minutes is a reasonable first-half-marathon range, but finishing comfortably is a better first target to go after.

Age, training and course profile all affect the eventual half marathon time, with a flat road race likely to be faster than a hilly or technical course.

What is the hardest half marathon in the UK?
What is the hardest half marathon in the UK?

If you’re looking for more of a challenge with demanding off-road courses, check out upcoming trail runs, including races with substantial climbing. Among half marathons with published figures, Solihull lists 192m of elevation gain, Wendover Woods Trail lists 181m, and Chepstow Running Festival lists 715 feet; Windsor Half Marathon and The Battlefield Run Naseby are also described as hilly by their organisers.
What is the most beautiful half marathon in the UK?
What is the most beautiful half marathon in the UK?
There are plenty of scenic half marathon routes throughout the UK, but a couple stand out. Run the Raid Lindisfarne Trail Half Marathon is a strong scenic choice, taking runners across the tidal causeway near Beal on the Northumberland coast. The autumn half marathon calendar also includes rural and trail races such as the Derbyshire Dales Trail Run, which has a 5.0 rating from nine finisher reviews. At least 122 upcoming half marathons describe themselves as trail races, giving runners a choice of coastal, woodland and countryside routes.
What is a good half marathon time for my age?
What is a good half marathon time for my age?
A good half marathon time changes as you get older, so it’s more helpful to compare yourself with runners in a similar age group. As a rough guide, an intermediate male runner might aim for around 1:47 at age 40, 1:56 at 50 and 2:07 at 60. For an intermediate woman, the equivalent times are roughly 2:04, 2:16 and 2:34. Don’t forget the course, either: hills, trails and bad weather can add quite a bit to a finish time, so you may prefer a flatter race from the November half marathon calendar. Remember you should think of these as useful reference points, not times you’re expected to hit.
