3 Things You Should Consider Before Signing Up To A Half Marathon

21st April 2022

By Beth Shelper

With race season fast approaching, we’re sure that many of you are considering signing up to a half marathon, or maybe even you’ve started your training for an upcoming race.

If either of these are true, you’ve probably got a lot of questions circling around your head that range from logistical points such as “how far is a half marathon?” to wondering what to wear for a half marathon, wanting to explore certain training strategies and necessary dietary and supplementation strategies too... we recommend The Energy Booster for that one. 

So, first off – if you’re considering running a half marathon this upcoming race season, congratulations! That’s great news, and something you should absolutely be proud of.

Here at Innermost, we’re all about setting challenging fitness goals for yourself to maximise your performance and improve your fitness, and love to champion our community for doing so. But one thing is for sure, you should be under no illusion that a half marathon (or any distance race) can be a pretty challenging feat, and it’s always important to be prepared.

Innermost's top half marathon tips 

To help you on your way to feeling ready and raring to go for that upcoming half marathon – perhaps you’re running in the Great Manchester Run, the Great Scottish Run or even the famous Robin Hood Half Marathon, we’ve got our top things to consider before signing up.

Firstly, though, let’s get some of the basics out of the way, shall we? As they always say, fail to prepare, prepare to fail! That’s exactly what we’re here to avoid.

How far is a half marathon?

When considering signing up for a half marathon, it’s of course pretty handy to know how far that means you’ll need to run. Whilst it may seem obvious to some, no one can deny that it’s a pretty important bit of information.

In miles, we’re talking 13.1, which translates to around 21 kilometres. For some, it’s easier to think of a half marathon as two 10k races, so if that helps – definitely use this technique as a guide!

How long does it take to run a half marathon?

This question, on the other hand, isn’t as straight forward. Your half marathon time will depend on a number of factors, including the below:

  • Your race experience
  • Your current injuries – if any
  • Race day weather
  • Your age
  • Any unexpected on-the-day occurrences

How to decide what to wear for a half marathon

When it comes to deciding what to wear for a half marathon, this largely depends on the weather. And if you’re running your half marathon in the United Kingdom, as we all know, it can be pretty hard to predict this… to say the least.

It’s important to remember that you’ll get warmer as the race goes on, so make sure whatever you wear is lightweight and loose. Remember to apply sunscreen before the race and reapply if you can, especially in hot weather.

For race days that are cold and rainy, a lightweight waterproof jacket is the perfect addition to your sportswear, with mid-lightweight leggings to ensure that you’re not too cold.

Our top things to consider before signing up to a half marathon

Now we’ve established the basics, let’s get into our top three things to consider before signing up to a half marathon. Preparation is key, so make sure you’ve thought about these before you commit!

  1. What training and experience do you have?

Whilst you may be able to run a half marathon comfortably on a warm, sunny afternoon with no company and in an empty park or familiar woodland, the race becomes a different challenge on a day with potentially unpredictable weather, thousands of other competitors, and potentially the pressure of family and friends watching, too.

Before signing up to a half marathon, consider your experience and make sure you have your pre-race routine and prep down to a T. Test out a variety of race wear, distances and even playlists to ensure that when it gets to the day, you know exactly how you race best so that you feel as comfortable as possible.

  1. Do you want to run the half marathon alone, or with a friend?

The answer to this question boils down to one thing: your pace. If you want to race with a friend, colleague or family member, make sure that you work out what their general pace is beforehand. You don’t want to run into some awkward mid-race situations where you either have to slow yourself down, or are struggling to keep up.

Another thing to consider in terms of running with company is whether you feel that you would benefit from the motivation or not. Whilst some people find company is a great way to motivate yourself to keep going during those particularly tough miles, others prefer to fully get ‘into the zone’ when running, and would find this a distraction.

Either way, think ahead and plan accordingly so that you know your game plan ahead of the day.

  1. Do you want to run for leisure, or for charity?

Finally, running a half marathon is a great thing to do, and many people pair this physical challenge with a passion or cause of theirs that they feel particularly strongly about.

Many half marathon runners set up fundraising pages in the run up to a half marathon to raise awareness and money about a cause or organisation, and it’s a really admirable way to both challenge yourself and do some good and give back to worthy causes.

Great charities that many individuals often run for include:

But of course, the number of worthy causes and charities are endless, and would be thrilled to receive donations of any size. 


We hope that these tips and tricks are useful in your preparation for your upcoming half marathon, and wish you the best of luck. Remember to train well, stay hydrated and never forget the importance of nutrition. That's the key.

From the Bedroom to the Gym: Is Your Sex Life Affecting Your Workout Performance?
The relationship between sex and workout performance is one that’s long been debated by scientists and fitness fanatics alike. It’s complicated and multifaceted, so answering the question of whether your sex life is affecting your training is difficult. That said, today we’re going to take a look at a variety of evidence, both academic and anecdotal, as well as several different scenarios and at least try to reduce some of the mystery around the subject. First, it helps to understand what’s actually happening to the body, both physically and psychologically, during both activities.   The Effects of Sex on the Body Sexual activity causes several changes to occur in the body:   Physical Changes That Occur During Sex During sexual activity and the lead up to it, the human body undergoes a process known as the sexual response cycle. This is the case for both males and females, though the cycle can be highly individual and may not be the same each time for each person. Describing the full sexual response cycle is beyond the scope of this article, however it consists of 4 phases: Desire Arousal Orgasm Resolution Factors such as elevated heart rate, increased blood flow and pressure and heightened muscle tension all come into play. If you’d like to read about the sexual response cycle in more detail, check out this great article from Cleveland Clinic.   Psychological Changes That Occur During Sex Several psychological changes occur both during and after sex. Most notable are the release of endorphins and oxytocin, which are associated with improved mood and a better sense of wellbeing. These are also responsible for reduced stress levels, which brings a multitude of additional benefits that are of particular interest to those of us participating in regular training and exercise. Cortisol, the hormone responsible for stress, is catabolic in high levels, meaning it can cause the breakdown of lean tissue. So, whilst it is unclear whether sex itself affects workout performance, the reduction in stress levels it may bring is definitely beneficial for preserving our results!   The Effects of Exercise and Training on the Body Exercise and training also cause the body to undergo a number of changes. These occur both during and after the physical activity. There are in fact a number of similarities in changes that happen during exercise and sex:   Physical Changes That Occur During Exercise The physical changes that happen in the body vary based on the type of exercise being undertaken, however, there are some that are common to exercise in general: Increased heart rate Increased blood flow, especially to the muscles Faster, deeper breathing due to additional oxygen needs Heightened activity within the circulatory, respiratory, musculoskeletal and endocrine systems A full summary of the changes that occur within these systems can be found here. More aerobically demanding exercise will, of course, place greater emphasis on the circulatory and respiratory systems as well as causing fat to be metabolised as an energy source. Resistance training, which often relies more heavily on the lactate and creatine phosphate energy systems, instead promotes greater muscular and endocrine (hormone) activity. Note the common physical changes between sex and exercise here, as they do crossover!   Psychological Changes That Occur During Exercise The psychological changes that occur during exercise are similar to those experienced during sexual activity and are mostly related to the release of endorphins and other ‘feelgood’ hormones. These help to regulate mood, and it is common knowledge that frequent exercise and leading an active, healthy lifestyle promotes a feeling of wellbeing.   Does Sex Affect Our Workouts? This is where things become complicated. Though extensive studies have been done on the subject, the results of these have varied massively. We must also take into account the experience of individuals, and this anecdotal evidence again has huge variance. Let’s look at both:   Sex and Training: What the Science Says Scientific studies on the relationship between sex and training are contradictory at best. There’s no denying the positive benefits of both activities, particularly from a psychological perspective, but as for the effect of sex on actual performance in the gym the results are inconclusive. A study, published in April 2021, by Kirecci, Albayrak and co. examined the effects of sexual activity of 50 men in the 24 hours prior to training on lower body strength. The study measured effects by having the men perform 3 separate squat sessions, each at the same time of day. Each of these sessions occurred after participating in or abstaining from sexual activity the night before. The men performed 5 sets of 5 repetitions of their maximum squat weight during these sessions and the difference in weight lifted was observed. The study concluded that ‘sexual intercourse within 24 hours before exercise [has a] detrimental effect on lower extremity muscle force, which suggests that restricting sexual activity before a short-term activity may be necessary.’ Aside from this study, most others found either no notable relationship between sex and athletic performance. A meta-analysis of 9 crossover studies, conducted by Zavorsky and Brooks and published on 16 September 2022, confirms this. The analysis concluded that ‘The results demonstrate that sexual activity within 30 min to 24 h before exercise does not appear to affect aerobic fitness, musculoskeletal endurance, or strength/power.’ This is perhaps more notable, because these studies incorporated different types of exercise and were not restricted purely to a strength/power based activity like squats.   Anecdotal Evidence: What About the Experiences of Real Gym Goers? The anecdotal evidence is, as expected, highly individualised. However, there tends to be a bias against the results of most studies, particularly in those participating in sports involving strength and aggression. For example, many fighters claim that they perform better when they abstain from sex in the days leading up to a contest. Similarly, bodybuilding forums are full of debate on this topic and many claim they note a significant decrease in motivation to train at maximum intensity after sexual activity. It has been hypothesised that this may be due to a downregulation in testosterone production after sex; during orgasm the mineral zinc is released in the body and this is also a precursor for natural testosterone production in the body and may, therefore, provide some reasoning as to the experience of many trainees.   Key Takeaways The relationship between sex and workout performance will always be a complicated one. The effects of one on the other in terms of physical fitness and, in particular, mental wellbeing, are clear, but when it comes to actual performance this appears to be highly individual. We’d advise doing what feels best for you but not worrying too much about it. Instead, prioritise your nutrition and make sure you’re fuelling your workouts properly.
