How to Choose Your First Marathon for a Better Race Day Experience
Updated: Sep 23
So you want to run a marathon? Maybe you just watched the Boston or London marathon this week, or your social media feed exploded with joyous photos and inspiring stories from the finish line of one of these World Marathon Majors or a big local race. Those runners look so proud and happy; the atmosphere seems electric.
You can't help but wonder: “Could I do it too?”
Short answer: YES! You absolutely can.
But before you hit “Complete registration,” take a moment.
The emotions and FOMO you’re feeling right now are powerful motivators, even when you’ve never run a marathon before. It's this moment of inspiration that might get you to sign up. But it’s not what carries you through months of training, early alarms, the increasing fatigue in your legs, and long runs in questionable weather.
Running a marathon is hard, and training for one is a huge commitment. Choosing the right race won’t make it easy — but it will make training more enjoyable, the race more meaningful, and having a positive experience a lot more likely.
Whether you're a planner, overthinker, or just slightly Type A in that very runner way, this guide helps you select a great first marathon for you.
To choose your first marathon the smart way, start with a shortlist and do some research, considering the following for each race you’re interested in:
Time and training schedule
Location / travel
Course and race size
Motivation / meaning
Let's break it down.
1. Marathon training takes a significant amount of time.
Picking a marathon with your kids’ school calendar in one hand seems like a really boring way of doing it, but marathon training takes serious time and dedication. Many runners get so focused on their dream of crossing the finish line that they forget to consider what it takes to get to the starting line.
This is the foundation everything else sits on.
Most marathon training plans take 16-20 weeks and assume you’re already running consistently — for novices, at least 3 times per week and an hour or more for your long run. If you’re not there yet, you’ll need extra time to build a base before training even begins.
Once you’re ready to start marathon training, you’ll need 4-5 months when you can make running a priority — not the most important thing, but something you will occasionally need to organize your life around. Consider also whether you have a strong preference for either winter or summer training, as the timing of your marathon dictates the season and weather you’ll be training in.
Questions to ask yourself:
When do I realistically have 4–5 months to prioritize running?
What’s my starting point right now; do I need extra time before I’ll be able to start a marathon training plan?
Will my peak training weeks (the last couple of months) fall during a predictable period of life?
Am I going to be happier training through winter or summer weather?
Start making a shortlist of races that fit your ideal timeline, and open it up a little bit to include a few more options. Be honest about races that just don’t fit.
2. The location of your race affects more than just the cost of travel.
Location isn’t just about where you run and how much it will cost to get there. It shapes the entire experience around the race.
Imagine this:
You’ve traveled for your marathon and you’re in a new city. The energy is high, everything feels special, and the whole race weekend has that “this is a big deal” feeling. You make a trip out of it, explore a little, and stay to celebrate after.
Destination races can be incredible experiences. Zoom in a bit, however, and you’ll also have to figure out where to eat the night before, navigate transportation to the start line in the dark, sleep in a different bed, and manage your nerves in an unfamiliar place.
Compare that to staying local:
You wake up in your own bed, then eat your usual breakfast. You know exactly how long it takes to get to the start. Maybe a friend meets you there, or you spot lots of familiar faces along the course. You feel supported and comfortable.
A local race might feel less exciting, but for a first marathon experience it’s often calmer and less stressful.
Things to consider:
Travel time, cost, and logistics of getting to the race
Time zone changes and how well you normally adjust
Access to support (friends, family, familiar routines)
Neither option is better. One just might suit you better right now. A lot of this comes down to your personality and previous race and travel experience.
3. The course and size of the race can make or break the experience.
26.2 miles is always 26.2 miles... but not all marathons feel the same.
Picture yourself at mile 18.
In one race, the streets are lined with people. There’s noise, music, cheering — constant energy carrying you forward. You’re surrounded by other runners, and even when it gets tough, you’re not alone.
In another, the course stretches out ahead of you. It’s quieter. Maybe you’re running through beautiful scenery. There are stretches where it’s just you, your breath, your thoughts, and the rhythm of your steps.
Sit with that for a while. Which mental image draws you in more? Both can be amazing. And both can be challenging in different ways.
Pros and cons of a big race:
+ Great energy and strong crowd support
+ You’ll always have others running at your pace
+ The experience of a “real event”, from race expo to finish line festivities
- Less personal space on the course and longer lines for everything
- Logistically harder and more stressful
- Loud spectators and navigating the crowds can feel overwhelming
Pros and cons of a smaller race:
+ Easier to run your own race and not get caught up in someone else’s race plan
+ Simpler, more relaxed experience
+ Many smaller marathons are scenic with a friendly and welcoming atmosphere
- Less crowd energy and lighter spectator support on the course
- More time running on your own or in a small pack, a quieter feel
- It may not hold the prestige of a big, well-known race
Once you’ve checked out the field size (and any helpful reviews about the vibe and experience on the course), remember to also think about the course profile, elevation changes, and typical race day weather. If you're picking a hilly race but you live and train somewhere flat, you're setting yourself up for an added challenge.
For a first marathon, simple is often a good thing. Not because you can’t handle a challenge, but because you’re already doing something new and demanding.
Questions to ask yourself:
Do I draw energy from crowds or do I prefer my own space and quieter surroundings?
Do I want to feel part of something big, or is this more of a personal challenge?
What conditions will I realistically be training in, and how close is that to the course profile?
4. You need a strong motivation to keep going when it gets tough.
At some point in your training, the excitement will wear off. There will be runs you don’t feel like doing, weeks that feel heavy, and many moments where the finish line feels very far away. But the hard work should still feel worth the effort and commitment. That’s where this piece matters — maybe more than any of the others.
Imagine two versions of a tough training day. You’re heading out the door, though you really don’t feel like running. As you step outside, you think:
“I have to do this.”
Or: “This matters to me.”
That's a powerful difference that comes from a deep personal motivation and a meaningful “why” for your journey. Daily motivation comes and goes, and a more personal reason to persevere helps you get through the hard days.
Questions to ask yourself:
Is there a race that feels personally meaningful?
What about it draws me in?
Does this choice actually excite me?
How will I feel when I complete the marathon?
If a race looks perfect on paper but doesn’t spark anything in your heart, it may be harder to stay connected to it when things get tough. Even if the travel budget fits and the training weather looks good.
Or it could be that your real motivation is tied to completing a marathon, less so to any particular race. Explore what is behind that motivation, what it means to you on a deeper, emotional level. That’s the well you draw from as you train for the big day.
So, how do you choose your first marathon?
Some factors need to fit: your schedule, your current fitness, your capacity to train. Others are more flexible. It’s up to you to decide which ones are your priority.
The goal isn’t to find the perfect marathon. It’s to choose one that works for your life and gives you something to look forward to along the way. If your first marathon is a great experience, it's a lot less likely to become your first, last and only marathon!
Make that spreadsheet and think through the practical side. But ultimately, trust your gut. Pick a race that makes the training feel purposeful — not just something you have to get through.
Remember: You’re not planning a business trip, you’re planning for an experience and challenge you want to celebrate and be proud of!
