Masters (40+) Half Marathon Training Plans


Is A Masters Half Marathon Plan Right For You?

Our Masters Half Marathon training plans are designed for runners over 40 years old. Although plenty of younger athletes love them too.

The workouts are just as tough as with our normal training plans, but with more scheduled recovery days. And more strength and conditioning work, so you stay strong and flexible.

Masters runners face different challenges to younger athletes. Families, busy careers and lack of sleep are just a few. That said, not all over 40 runners require a Masters-specific training plan. Some find it easy to carry on with a normal training load, while others need to change their approach to training.

When to Consider Choosing a Masters Plan:

  • Your training time availability is reduced with work and family commitments.
  • You feel sleep deprived from daily stresses.
  • Your body has different needs in terms of recovery, strength and flexibility training.
  • You suffer recurrent injuries.
  • You feel constantly fatigued or overwhelmed by your regular training.
  • You keep catching colds and other viruses.

Can I Still Race Successfully?

Yes! In fact, by following our Masters running plans, you may well race better than ever. The key to success is training consistently, without missing workouts due to injury, fatigue or time limitations. It’s not always about who attempts the most training.

All our training plans adhere to the principle of “Progressive Overload”. Meaning that the stress placed upon your body gradually increases over time. By training consistently with regular recovery periods, you’re more likely to absorb the gradually increasing training loads, without breaking down.

How is a Masters Plan Different?

Intensive half marathon training will cause you muscle damage. As we mature it can (arguably) take longer for your muscles to adapt and remodel. This decline in rate of recovery will vary according to genetics and training history. Insufficient recovery time can lessen the effect of the workout and leave you more prone to injury. Masters Half Marathon plans have more rest days each week (1 or 2 days per week) and a 1:2 ratio of active recovery weeks to hard weeks (this is 1:3 in regular plans). That means you’ll do two weeks of challenging training, and then take an active recovery week (with around half the training stress).

As we get older, our muscle density begins to decline, and it becomes crucial to counter the effects of age-related muscle loss.

Our Half Marathon Masters plans normally have two scheduled strength and conditioning workouts per week, designed to promote:

  • Performance through improved strength and power.
  • Increased muscle mass.
  • Injury prevention by strengthening connective tissue, muscles, and tendons.
  • Flexibility to maintain power through a full range of movement.
  • Improved bone density.
  • Fat-free body mass (a leaner physique).

All Strength and Conditioning workouts can be carried out at home. There are also alternative exercises if you prefer a gym based workout. 

Training intensely is the key to success in any sport, regardless of age. Strong performances come from having a solid base and workouts that maximise your anaerobic fitness, speed, power and skill. Evidence suggests that higher intensity work with less volume is beneficial for the Masters athlete, even for Half Marathon Training. Shorter, more intense workouts will also free up valuable time for recovery and work/family commitments. Masters plans optimise your training time with the right ratio of volume and intensity relevant to each plan. 

As an older athlete with a full life, prioritising is an essential skill. Ideally schedule your week, planning times for family, training, work and sleep. You should also be prepared for the curve balls that cause chaos in your best laid plans. Consistency in training is arguably the most important trait amongst successful Masters athletes. Here are some ideas to help you stick to your regime:

  • Use your commute as an opportunity to train.
  • Add in strength and conditioning at home, with the kids if necessary!
  • If you can’t do a whole session, do part of it, something is always better than nothing.
  • Commit to a lunchtime workout.
  • Double up run workouts with Strength and Conditioning sessions and save showering twice.
  • Life will occasionally get in the way and if you need to miss the odd workout, let it go and move on. It happens.

Top Training Tips For A Half Marathon

If you’re a total beginner your runs should start off at 15 minutes in duration and increase gradually over a period of weeks or months. If this feels too hard for you, walk briskly instead, until you’re fit enough to include a little running in your workouts. Over time you will be able to run more and walk less. Aim to increase the duration of your workouts by no more than 10% per week. Your runs should not feel too intense at this stage – ideally you should be able to talk while you’re running, as a way of knowing that you’re not going too hard. If not, slow down or include some walking sections.  If you ignore this, you increase your risk of getting injured.

Once you have built up to running 30 minutes comfortably, you can then structure your training program around three key runs per week. The first key session is an endurance session, where you build up over the weeks and months to around 1 hour 30 minutes of low intensity running.

The second key session is a speed session, with a warm up, a warm down and some hard efforts sandwiched in between – such as 4 x 3 minutes hard with 2-minute recoveries.

The third key session should be a run that includes some half-marathon paced efforts, so you get used to the demands of race day. For example, 2 x 10 minutes at half marathon pace, with 3-minute recoveries (plus, warm up and warm down). We include these kinds of workouts in our half marathon training plans.  All your key sessions should constantly evolve and progress over time, so your body is forced to adapt and improve.

If you do additional runs, they can be steady jogs of around 30-60 minutes. If possible, do some of your running on soft surfaces like grass or trails, to reduce the impact on your body. Training on hillier terrain is good too, because it spreads the load to a wider range of muscle fibers, compared to running on flat ground. Always be mindful of avoiding injury – over half of all runners are injured every year. In our novice, intermediate and advanced half marathon training plans we make every third week an “active recovery week” where the training is halved. This gives your body a chance to recover and get stronger.

In our half marathon training plans we include two 45-minute strength and conditioning sessions each week. These workouts can help improve your strength and flexibility, leading to more efficient movement patterns and fewer injuries. We suggest you only do strength work in addition to at least three runs per week, rather than instead of them.

Using A Masters Half Marathon Training Plan

Online training plans are for athletes who don’t feel the need for a personal coach, but who still want the structure and planning of an expertly-written training program. Research has shown that you are twice as likely to reach your goals if you train with a structured plan. 

If you have a recent background of fitness or sport, it could take you 15+ weeks to get fit enough to conquer a half marathon. If you’ve been more sedentary over the last few years, it’s harder to predict. Either way, you need to build up your training gradually over a period of months. Fitness improvements build up slowly and gradually, like coffee dripping through a filter into a jug.

We have a huge range of plans that enables you to select one that best meets your goals, schedule and ability. If you’re not sure where to start, read on below for a quick overview.

Length of Plan
For the best outcome, count back from your “A” target race date and simply choose a plan to fill that gap (you can still work in other, smaller races during your plan). Note that longer plans start easier and progress more gradually than shorter plans. The body responds best to constant, gradual progression with regular recovery periods, and that’s exactly what our plans are designed to give you!

Level of Plan
Choosing the correct level will help you get the most out of your plan. Generally, if you’ve never done this event before or currently train up to a few times per week, you might consider a Beginner plan. Alternatively, if you’ve done this event many times before or currently train 5+ times a week, you might consider an Advanced plan.

But don’t worry too much – we also let you swap the level for free within 14 days of purchase, if you find it too easy/hard!

Visit the MyProCoach Help Center for further guidance and to contact our Certified coaching team.

Certainly! Our training plans allow you to easily swap a few days around each week to suit your availability. Or you can swap out a session, to attend a similar group workout instead. That’s fine. If you opt for Training Peaks Premium (from $9.92 per month) you can even drag & drop your workouts onto different days. We give a few recommendations on how to best do this in our help centre.

And you can also train for multiple events! Our training plans guide you up to your target “A” race, but it’s also good to include some “B or C” races along the way. Our help centre goes through the exact steps you should take to enable you to get full benefit, without detracting from your key focus.

I can't tell how much I am enjoying the plan. It's amazing to know what training I am going to do weeks before. I am very grateful for your programs. ​Thank you for all your hard work.
Rachel Kjearsgaard - April 2018
After 5 or so weeks of using your program I'm already reaping huge gains! It's amazing how important it is to be consistent with training. I used the less intense schedule of the Prep Phase to get accustomed to the routine and ensure it got done every morning. I'm already running 5k's in just over 20 minutes which is faster now at 40 years old than when I was in high school and in my mid 20's. Needless to say I'm stoked about the upcoming season.
Daniel Dragic - Feb 2018
I have to say, I am absolutely loving the variation in the training and really enjoying the different sets. ​
