Running a good half marathon time is something every runner has on their 'To Do' list. Whether it’s a trail race or a road race, a 13.1 mile half marathon is the natural next step up from 10k, and one of the classic benchmarks to test yourself against. 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 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.
