Let’s figure out your starting point with running
In the world of running, gauging your ability level is more of an art than a science. There’s no one-size-fits-all approach, and it’s important to remember that everyone’s journey is unique.
Here’s a guide from Mcmillan Running to help you get a sense of where you might stand:
New runner: If you haven’t logged many miles yet, you’re in the ‘new runner’ category. You’re building your running from the ground up, and that’s where the adventure begins.
Beginner: You’re no stranger to the running game, but the half marathon is still uncharted territory for you. Running 3 to 4 days a week for at least 30 minutes means you’ve already built some endurance and consistency.
Intermediate: You’ve completed a half marathon and you’re comfortable running 4 to 5 days a week. Your typical outings range from 30 to 45 minutes, and your long runs stretch to over 60 minutes. You’re also diving into some speedwork sessions each week to enhance your performance.
Advanced: Running has become a significant part of your life. You’re out there 6 days a week, dedicating about an hour to each run. And your long run? That’s grown into a 90-minute journey. Speedwork isn’t just a weekly affair; you’re incorporating multiple sessions to keep pushing your limits.
Remember, there’s no one right way to gauge your running ability. These categories offer a general guideline, but what really counts is your personal journey and goals.
How long do you need to train for a half marathon if you’re a beginner?
For new and beginner runners, you’re looking at a half marathon training window of around 12 to 16 weeks to train for a half marathon. This longer training period isn’t just beneficial; it’s crucial because it allows for a gradual buildup of your endurance without risking an injury.
Let’s dig a little deeper about why you need a few extra weeks.
Build endurance. For those just stepping into the world of half marathon training, it’s all about building endurance from the ground up. You’ll need a few extra weeks to gently build your cardiovascular endurance and muscular strength, which are essential for taking on the 13.1-mile challenge.
Avoid injury. Rushing headfirst into half marathon training without a solid running foundation can spell trouble in the injury department. But that’s where those bonus weeks become your secret weapon—they give you time to ease into running longer distances without getting hurt.
Mental prep. Let’s talk about something that’s sometimes overlooked—building up that mental fortitude for running a half marathon. It’s what will keep you lacing up your running shoes, finding the strength to push through those final miles, and perhaps most importantly, being kind to yourself along the way.
Here’s an example of the first weeks of a beginner half marathon training program:
Monday: Let’s ease into the week with a 3-mile easy run.
Tuesday: Dedicate 30 minutes to cross-training, whether that’s cycling workouts for runners or leg workouts for runners to strengthen your running.
Wednesday: Keep it easy and chill with a 3-mile easy run.
Thursday: Do another 30-minute cross-training session to maintain your overall fitness.
Friday: Take the day off so you’re ready for tomorrow’s long run.
Saturday: Ah, the long run—it’s 4 miles today, done at a comfortable pace. Don’t worry about how slow you think you’re going! It’s all about getting used to being on your feet.
How long does it take to train for a half marathon when you’re an intermediate runner?
If you’re an intermediate runner looking to take things up a notch and aim for a personal record (PR), you’re looking at a window of 8 to 12 weeks to train for your half marathon. In these 8 to 12 weeks, you’ll build your running foundation without the threat of overtraining or running burnout.
Let’s have a closer look at how you’ll prepare for a half marathon.
Balance running and recovery: As you aim for better performance, your key lies in preventing injuries and maximizing your training efforts. Striking the right balance between challenging runs and essential recovery periods is your key to achieving your new half marathon personal record.
Recovery isn’t just downtime—it’s vital. Adequate sleep, a balanced nutrition plan, and regular rest days are the holy trinity for you as an intermediate runner striving to reach new PRs. And here’s one more half marathon training tip—consider adding cross-training activities like cycling for runners or leg workouts for runners to your plan to shield you against overuse injuries.
Boost your pace: If you’re an intermediate runner, consider infusing your half marathon training with some advanced training elements like interval sessions to fire up your speed, tempo runs to push your pace, and hill running workouts to build strength in your legs.
These workouts aren’t random; they’re part of a strategic game plan designed to boost your running efficiency and half marathon time. You’re moving up from the basics, but remember, these runs only make up about 20% of your weekly mileage to help you steer clear of any unwanted injuries.
Focus on your race day pace: Race-specific training is where it all comes together. When you practice your race pace, you’re not just running; you’re building a deep familiarity with the intensity and demands of that specific speed. Think of it as a dress rehearsal for the big show, where you fine-tune your pacing, make adjustments, and get comfortable being uncomfortable before race day arrives.
So how should you practice your race pace? Consider doing a shorter race, like a 5k or 10k. These races aren’t just about the mileage; it’s where you gauge your progress, refine your pacing, and bask in the electrifying race day atmosphere.
Here’s an example of a sample week of an intermediate half marathon training program:
Monday: Kickstart your week with a gentle, conversation-paced run.
Tuesday: Track day! Elevate your speed with 400m repeats to fine-tune your pace.
Wednesday: Dive into some cross-training with options like cycling workouts for runners and leg workouts for runners to strengthen your running.
Thursday: Challenge yourself with a tempo run, designed to boost both your speed and endurance.
Friday: Embrace a day of rest or opt for a recovery run to prime your body for the long haul.
Saturday: Welcome to the long run—It’s a long run day, your chance to prep your body and mind for your half marathon challenge.
How long does it take to train for a half marathon when you’re an advanced runner?
If you’re an advanced runner, your half marathon training timeline may span a short 8 to 10 weeks.
Why so short, you ask? Well, it’s because you’ve probably already put in the miles and built an impressive running foundation that allows you to fast-track your half marathon progress.
Let’s explore what you can expect in your half marathon timeline.
An advanced half marathon training program includes various components to help experienced runners like you improve their performance.
Here are the key elements typically included in an advanced half marathon training program:
Higher training volume: Studies have hinted at something intriguing – higher training volumes, often cruising past the 32 km or 20-mile mark per week, could be the key to crossing off that new personal record. 1
Long runs: Long runs take center stage in your half marathon training. That’s because long runs prep your body to meet the demands of racing for 1.5 to 2.5 hours. This is where you ramp up your endurance, fortify your mental game, and nail down your half marathon nutrition strategy.
Tempo runs: Tempo runs improve your endurance by pushing your lactate threshold to new heights. So don’t shy away from weekly tempo runs because you’re learning to hold a faster pace for miles.
Interval training: Interval training—it’s about balancing high-intensity bursts with a period of recovery to upgrade your running economy and anaerobic threshold. So in advanced half marathon training, include reps of 400m, 800m, or 1,200m at a faster pace than your goal half marathon pace.
Strength training: Strength training boosts your running economy, injury-proofs your body, and sharpens your performance. Your focus? Target the muscles you use for running, such as squats and lunges. Set your sights on incorporating strength training sessions, each lasting around 30 to 45 minutes, into your routine 2-3 times a week
Here’s an example of a sample week of an advanced half marathon training program:
Monday: Start your week with a gentle, comfortable paced run.
Tuesday: Get ready to conquer the track with speedwork. Try 400m repeats to sharpen your speed.
Wednesday: It’s time for an easy run, followed by some leg workouts for runners.
Thursday: Push your limits with a tempo run to enhance your speed and endurance.
Friday: Grab some rest or opt for a recovery run to prep your body for your long run.
Saturday: It’s long run day, your opportunity to prep your body and mind for your half marathon.
To wrap it up, as you embark on your half marathon training, you’ll inevitably face the question of: ‘How does it take to train for a half marathon?’ The answer is rarely straightforward but here’s a general guide.
