A race strategy that tells you how to run a half marathon in 2 hours or less looks at everything from your pace to your form. 

Running a sub-2 hour half marathon is a huge achievement. If your training for your next half marathon, you may be wanting to achieve your next PB.

I remember when I first started running half marathons, a race time of 2 hours or less seemed like a distant, unachievable goal.

But if I’ve learned anything as a runner, is that if you put your mind to it, you really can achieve whatever you set your sights on.

According to a recent study on pacing during a half marathon, the half marathon is the most popular endurance running race in terms of number of races and runners competing annually.

So if you’re looking to improve on your race times, here are my top tips on how to run a half marathon in 2 hours or less.

Be sure to check out my first half marathon tips and head on over to my post on 6 ways to recover after a half marathon.

Break down your times

A big part of your sub-2 hour half marathon strategy should be to break down your current run times. 

In order to run a half marathon in 2 hours or less, you need to have hit the following running milestones:

  • Weekly mileage – 15-16 miles
  • 5k time – 25-26 minutes
  • 10k time – 54 minutes or less
  • Half marathons completed – one or more
  • Half marathon PB (good conditions) – 2:04-2:06
  • Half marathon PB (hills, heat or wind) – 2:08-2:12

If you’re a beginner runner, then my advice would be to start with a shorter distance like a 5k or 10k before attempting a half marathon.

Check out my posts on how to run a 5k in 25 minutes or less and how to run a 10k in 60 minutes or less for my tips on running these distances too.

Once you’ve mastered the 5k and 10k distance and have achieved times closer to those listed above, then it’s time to start working towards the half marathon distance.

Practise your race pace during training

A large part of your sub-2 hour half marathon strategy is your training plan. Many races are made or broken even before the race has begun.

You need to condition yourself to feel comfortable running for 2 hours, and not feel broken afterwards, and even during the race.

If you’re used to running 5k and 10k races, you’re used to sustaining your 5k or 10k race pace for 3 to 6 miles.

This pace will take its toll after a while, so for a half marathon you need to approach it differently.

A sub-2 hour mile works out at 9.09 minutes per mile, or 5.40 minutes per kilometre.

Ask yourself – could you sustain a 9.09 minute mile pace throughout the whole race?

It would be a shame to miss out on your sub-2 hour goal by a few seconds, so practise running at a 9.09 mile pace during your training.

When you step up from a 5k or 10k race to a half marathon, adaptations in your body need to take place. 

In other words, your body needs to get used to the intensity of running a 9 minute mile for two hours straight.

Fuel your race

Food and nutrition is incredibly important for a successful sub-2 hour half marathon strategy.

Think of your body as a machine, it won’t function properly if you put the wrong type of fuel in it. Likewise, it won’t function properly if you don’t give it enough fuel. 

Fuel before, during and after your race so you don’t succumb to fatigue and tiredness. 

My post on what to eat before a run has got you covered when it comes to the types of foods to prioritise before a run.

It’s also wise to avoid of these common pre-run eating mistakes before your race.

Strengthen your core

Your core is extremely important when it comes to running. A strong core helps you hold a strong and stable position for longer.

Include core workouts in your weekly training routine. Exercises like plank, side plank, bicycle crunches, Superman pull, lying windscreen wipers are all good examples of core stability exercises for runners. 

Stuck for what to include? Check out my post on some essential core exercises for runners.

A lot of core workouts are easy to do at home as no equipment is needed.

Strength train

Strength training is key for any runner looking to run faster for longer.

It is important for runners is important because it helps you build stronger muscles, tendons, ligaments and connective tissues. It also improves your speed and power and lowers your risk of injury.

Strength training also contributes to better running form. In other words, it helps you run more efficiently!

Perfect your form

Proper running form is all about running in the most efficient way possible. 

Inefficient running form can shave valuable seconds off your running time.

If you’re looking for simple ways to improve your form, check out my blog on how to improve your running form.

The idea is that these simple tips can help you tweak your running form so you run more efficiently for longer.

Do hill repeats

Hill repeats are a great way to improve your power and strength as a runner. 

Include at least one hill training session in your training plan and you will reap the rewards on the race track.

Try and land on your forefoot (near your toes) when running uphill. Use your arms to really propel you forward. 

Allow yourself to relax and stay forward on your toes rather than sinking back into your heels on the downhill run.

You will gain speed instead of hitting the breaks. 

If you struggle to get out onto hills during your training, there are plenty of treadmill workouts that you could try.

By using the incline function on the treadmill, you mimic outdoor runs. 

An incline of 2 to 3 is great for long, uphill run training, which is a great strength builder. Whilst an incline of 4 to 7 is good for quick hills varying in length.

Do speedwork

Speedwork is a game changer for a lot of runners who are working towards a PB, or just generally want to run faster.

Speedwork includes interval training, tempo runs, Fartlek training and strides.

Try and include at least one speedwork session in your training plan each week. 

At the start of your training plan, include an interval session then gradually increase its intensity over the following weeks. 

For example, with interval training, increase the amount of work and decrease the amount of rest.
