There’s that moment when you hit the “confirm” button for a marathon, and you feel that rush of excitement. And then a few beats later, if it’s your first time, especially, you wonder, how long does it take to train for a marathon, really? What does it take to run 26.2 miles?
The honest answer is that it depends. Yeah, it’s not what you want to hear, but this article will break it down properly so you’re free from injuries, safe, and able to run a great race. The name of the game is to prepare and train correctly to have a great race at one of the best marathons.
How Long Does It Take to Train for a Marathon, on Average?
For the most part, a marathon training plan takes 16 to 20 weeks, or about 4 to 5 months. Overall, planning depends on your age and fitness level. It also depends on whether you’re a new runner or someone who’s got miles.
If you run consistently and log consistent miles, your training window will be shorter. But for new runners or those returning after time off, you’re better off planning a marathon training regimen.
Factors to Consider When Training for a Marathon
The standard rule of thumb for a marathon training plan gives you a framework. But remember, it’s just a starting point. For instance, if you get injured along the way or haven’t trained in a while, you may need more time to train. The following shapes how long it’ll take to prepare.
1. Current Fitness Level
If you run more than 20 miles a week, you have a solid foundation. You can likely achieve a 16-week marathon training plan. If you haven’t been running at all, or only sporadically, plan for 24 to 30 weeks.
2. Injury History and Risk
If you’ve experienced stress fractures, plantar fasciitis, or knee problems, you need to build more time into your marathon training regimen. Ideally, speak to a sports medicine professional or physical therapist before you begin, and consider a good marathon coach.
3. Lifestyle and Schedule
A typical week during peak training is four to five runs, including weekends. That means a stretch of time of about 2 to 3 hours. If you have lots of other commitments, then build in extra weeks into your marathon training plan.
4. Age and Recovery Rate
Older runners need more recovery time between runs. It’s important not to think of it as a limitation, but as useful and essential info. Someone who’s over 50 should build a marathon plan with extra rest days for smarter training.
5. Race Goal
The race goal is also important to understand. Looking to “just finish” is different than looking to chase a Boston Marathon qualifier. The first allows more flexibility, and the latter means a more structured marathon training plan.
What Does a Standard Marathon Training Plan Look Like?
A marathon training plan, as mentioned, runs about 16 to 20 weeks. It’s founded on a few core principles, including gradually increasing distance and miles, adding one long run each week, and building recovery time. Depending on your goals, it may also include cross training.
That said, most plans follow the following framework:
- 2–3 easy runs: moderately paced runs designed not to overtax the body
- 1 tempo or speed workout: faster-paced running to improve race-pace stamina
- 1 long run: the cornerstone of marathon training, gradually building to 10 miles and then 20-22 miles during peak training
- 1–2 rest or cross-training days: non-negotiable for recovery and could include cycling, swimming, or yoga
Example Marathon Training Regimen (18 Weeks, Intermediate Runner)
Now that you have several answers to, how long does it take to train for a marathon, let’s look at an example of 18 weeks of training for a runner who has been running.
- Weeks 1–3: Build the foundation and run long runs of 10–12 miles. Total weekly mileage: 30–35 miles.
- Weeks 4–6: Extend the long run to 14–15 miles. Add one tempo run per week. Total weekly mileage: 35–40 miles.
- Weeks 7–9: Long runs of 16–17 miles. Introduce race-pace miles within long runs. Total weekly mileage: 40–45 miles.
- Weeks 10–12: Peak long runs of 18–20 miles, which may be your hardest training block. Total weekly mileage: 45–50 miles.
- Week 13: First taper week. Reduce mileage by 20%. Long run drops to 14–15 miles.
- Weeks 14–16: Continue tapering. Keep intensity but cut volume. Long run: 10–12 miles by week 15, then a short shakeout run race week.
- Weeks 17–18: Race week and race day. Trust the training.
If you’re a beginner, you should add 4 to 6 weeks at the outset of this plan. Start with shorter long runs of 6 to 8 miles and lower total weekly volume.
