7 Things You Need To Know Before Running Your First Half-Marathon

If you are planning on running your first half-marathon this year, congrats! Hopefully you are excited for what is to come. If you are like I was before my first half you may be feeling a little bit lost. The good news is there are plenty of resources available to support you in your journey! As you are getting started with your training there are some things you need to know so you don’t make the same mistakes I did before my first half. Make sure to read on to find out 7 things you need to know before running your first half-marathon!

If you are getting ready to train for and run your first half-marathon you may be feeling a little bit lost. The good news is there are plenty of resources available to support you in your journey! As you are getting started with your training there are some things you need to know. Here are 7 things you need to know before running your first half-marathon!

7 Things You Need To Know Before Running Your First Half-Marathon

Before I start sharing some of the things you need to know, let me take a minute to tell you about my first experience running a half-marathon. It was 2007 and I had never done a race before. I trained and ran on my own, with the guidance of nothing other than Runners’ World magazine.

My training went ok, but I ran all my runs at the same moderate pace and just increased my long run each week. I didn’t know anything about fueling and therefore didn’t take any fuel in training or during the actual race. On race day I ended up in a porta potty line as the gun went off and started the race late (which was ok since it was chip-timed, but not ideal!). The race went ok until mile 10, when I realized I had never run that far before and it was getting hard. I pushed through and managed to finish, but there was no one there to celebrate with me at the end. Oh, and I should also mention that I wore the race shirt that day- but luckily it didn’t cause any problems!

I made alot of mistakes while running my first half-marathon, but luckily it worked out ok. It could have gone terribly wrong. Let’s talk about what would have been helpful to know before my first half!

The right gear matters

For a half-marathon, it’s usually not a good idea to wear the race shirt on race day unless you have a chance to practice running in it first. Most of the time you get your race shirt the day before the race so running in it isn’t practical. Instead, buy a few good pieces of running clothes and wear them for your training runs. Learn what works the best so you can plan to use those on race day. Same goes for shoes. Find one good pair and make sure they will last through your race. (Most will last for about 300-500 miles). The last thing you want to deal with on race day is blisters and chafing!

Training plans work

My approach to training was not ideal and could had led to injuries or not feeling confident enough to finish the race. I don’t recommend setting a time goal for your first half (just finish and have fun!) but it’s important to have a realistic idea of what your pace should be. A training plan can help you make sure you are running easy enough to get through all the miles. Most plans for beginners will include about 4 days of running with rest or cross-training on the other days. If you are running 4 days a week you want to spread them out and not do all the runs back to back so you have time to recover. Following a good training plan, or working with a coach, will help you get to the start line feeling healthy and confident.

Fueling properly is important

When you are running 13.1 miles you need to take fuel. Most runners will take at least 1.5 hours to cover the distance (and for beginners it’s usually at least 2 hours, or longer). Your body needs carbs during this time to run well and fueling is something that should be practiced in training. When doing your long runs you should take fuel on runs that are 80-90 minutes or longer. It can take some trial-and-error to figure out a fueling plan that works for you, but there are many resources available to guide you.

Slow and steady wins the race

Most runners do not need to set a time goal when running their first half-marathon. Slowing down, especially during training runs, will probably make the experience more enjoyable. When you keep your easy runs easy you are able to build up your endurance so you can run for the amount of time required to cover 13.1 miles. You are also less likely to get injured following this approach. As you become more experienced with racing half-marathons you can add in speedwork and work towards a time goal.

You can also consider trying out the run walk method!

Practice makes (almost) perfect

As you approach race day it can be helpful to practice things like what you will wear, what you will eat/drink, etc. It can also be a good idea to sign up for a shorter race during your training cycle so you are familiar with the race atmosphere. It can be intimidating to show up for your first half-marathon if you’ve never done any race before.

Support teams are for every runner

There are many ways to get support when preparing to run your first marathon. You can find a running group to train with, or recruit some friends/family members to train with you. Another option is to work with professionals, like a physical therapist, running coach, and/or registered dietician, depending on your needs. All these people can help support you as you prepare for your race. Here are more ideas for building your running support team.

You only get one first half-marathon

Most importantly, remember to have fun and enjoy the experience! You only get one first half-marathon, so make the best of it! Try not to put too much pressure on yourself and remember that finishing is winning.

    Great points, Lisa!
    I wish I had told myself not to start out too fast. I burned out around kilometre 15 and still had 6k to go – it was tough. As you say, slow and steady wins the race. It’s easy to let yourself be pulled by the other runners in the beginning, so it’s good to run by your pace on your watch.

      SO true! It can be really tempting to go too fast at the beginning, but a half-marathon is far so you really need to pace yourself!

    My biggest mistake in the early days of racing was poor fuelling! At the Soweto Half, I got to the end and almost collapsed. My husband had to pump me with Coca Cola and electrolytes just to get me to the car park! That was such an important lesson so I’m really happy this has made your list!

    • Lisa @ Mile By Mile says

      Oh wow, that’s scary! Fueling really is important but sometimes newer runners don’t think they need to worry about it since they are just starting out.

    I knew nothing when I ran my first.

    Great tips.

    Things we need to remember even if it’s our 50th.

      It’s so common to just jump into that first half without knowing much!

  4. Kimberly Hatting says

    I wish I would have known the difference between the various paces (5K, half, tempo, etc.). Like you, I also ran almost every training run at the exact same pace. I didn’t know the value of “slower” paces while in training. Thankfully, my race went well and I was able to run most of it at the same “training pace” I’d used, LOL

    • Lisa @ Mile By Mile says

      January 27, 2022 at 4:20 am

      It can really be problematic when new runners think they need to run all their training runs at a hard/fast pace!

  5. Deborah Brooks says

    January 26, 2022 at 8:15 am

    My biggest mistakes at the beginning were poor fueling and hydration. I still work on this! I also started way too fast. I still remember it being a great sense of accomplishment. There is always something to learn from every race

    • Lisa @ Mile By Mile says

      January 27, 2022 at 4:20 am

      So true. And yes, there are many things we still need to work on even after many years of racing!

    My first is still a great memory, despite it being my coldest (in Vegas — colder than it was back home in December!) and slowest (if you don’t count my trail half).

    I didn’t make too many mistakes — other than not checking out the info on the chip (because it was the type you tie on). My chip wasn’t for me! That definitely caused some angst, but I met up with some online friends while there, a couple of who were very experienced, and they took me under their wing.

    Obviously this doesn’t happen much anymore (it was 10 years ago).

    • Lisa @ Mile By Mile says

      January 27, 2022 at 4:22 am

      It’s always helpful to find a few people who are more experienced to help guide you through the process! That’s too bad about the chip- but even experienced runners may not have known to check the info on it!

    My first half marathon was very cold and windy but is such a fond memory. I did make the mistake of skipping coffee before the race even though I drank it before every long run!

    this is perfection. I think you covered just about everything. I love the point about there only being one first half. That is so true.

Yesterday’s long run was not what I wanted it to Yesterday’s long run was not what I wanted it to be. The plan was to take the day off from work, head to the trail where I could run 10 uninterrupted miles at MP (16 total) and practice my race day fueling while wearing my race day shoes.

What actually happened? All week I was stressed about this run and the condition of the trail. We had lots of rain on Thursday, and Friday was forecasted to be very windy. I tried to get in the best mindset possible, reminding myself that I won’t be able to control the conditions on race day. Meanwhile, I haven’t been sleeping well thanks to my 2 year old waking up every night, and my watch has been basically telling me that I’m losing all my fitness and need a week of recovery.

While I started the run feeling pretty good, after 11 miles (7 at MP) my stomach turned and I almost got sick on the side of the trail. I just couldn’t recover from that. The best I could do was run the rest of the miles easy, and needed some walk breaks. On top of that, my shoe kept rubbing my foot on top and I stopped twice to retie it. This has never happened before and now I’m questioning what shoes I should wear for the race. The trail was also in rough condition with several trees blocking it, lots of wet leaves, and rocks/sticks that I had to look out for.

I just can’t believe how bad I felt for the last 5 miles of this run and I can’t pinpoint the cause. Am I overdoing it with the fueling and can’t handle it on harder effort runs? Was it something I ate recently? The hard part is there’s no time to really try something different before the race, as all I have left is a 10 mile easy run next weekend.

I’m trying to remember that one bad run does not take away from all the good runs this training cycle. I’m using today to reset and move on so I can make the most of my last 2 weeks of training. It’s not the way I wanted my last big long run to go, but I suppose it was good practice for pushing through even when I felt pretty awful.

Who else has had a terrible long run close to your race?

#running #marathontraining #longrun
Spent almost every step of this 21 mile run questi Spent almost every step of this 21 mile run questioning my life choices. Like waking up at 3am to run 12 miles on the treadmill and 9 outside. This was a crazy week with a kid that wasn’t sleeping great and fighting a cold and super busy days at work. My legs were just tired the whole time today. It was really hard to run outside after so many treadmill miles and my pace was much slower than inside.

I reminded myself that this is peak week. It’s supposed to feel hard. If it was easy everyone would do it. I ran 53 miles this week and am not injured. The weather is perfect. I’ve gotten in every planned run of this training cycle so far.  I get to do this. 

And I managed to finish strong with my last 3 miles the fastest of the (outside) run. I owe that to a solid fueling plan and taking all my gels even when I really didn’t want to.

3 weeks to go until race day!

Yesterday’s long run was followed immediately by Yesterday’s long run was followed immediately by back to back kid activities, so there was no time to post about it. (I ate breakfast in the car and lunch at soccer practice- it was that kind of a day.) I was kind of nervous going in to this run, especially now that I’m getting down to last few key long runs. I had 16 miles with 4 x 2 miles on the plan, which sounded manageable but also challenging. The weather was perfect and I hit all my paces. At the end I got a little confused- thinking I was at 15 miles but I was actually at 14 🙃 Got home and realized I chafed really bad. Another long run down, and another week closer to race day.

Do you ever psych yourself out before long runs?
