Beginner Half Marathon Training Plan 12 Weeks

Our 12 Week Beginner Half Marathon Training Plan is a great plan for runners who have some short-distance experience, or perhaps are a little rusty and need to blow off the cobwebs prior to their half marathon!

It is a compressed version of our 16 week half marathon plan, and also includes the option of switching out a training run for a tempo run.

Tempo runs are great for runners with a specific finishing time in mind; they help you to train towards that time.

12 Week Beginner Half Marathon Training Plan

Who is it for?: 

Runners with some experience looking to rock a solid half marathon!   

How Long?: 

12 weeks // 3 months. This is an abridged version of the 16 week plan; if you’re confident that you can handle the faster mileage increases, this is the plan for you.

It includes 3 mid-week runs, to be performed at a comfortable pace, and one long-slow run each weekend to build your max mileage.   The plan includes one cross-training day per week and two rest days. 

Not convinced this is the plan for you?

How Many Days Per Week?:

The training plan features 5 days of training per week; 4 days of running and 1 day of cross training.

Training Runs

These are your classic training runs; do them in the mornings or after work, at a comfortable, sustainable pace.  

These runs help add mileage to your training week and get your body used to running far!

Cross Training

Each week includes a cross training day; although these aren’t mandatory, I highly recommend them.

Why?

Cross training is meant to work on your cardiovascular health and strength some of the muscles weakened through running.

Recommended cross-training exercises include body weight exercises, light gym work, swimming, yoga, pilates, and cycling!

Long Runs

You should be factoring in one long, slow run every weekend.  These runs are all about increasing your endurance gradually.

Remember to take it easy during them, don’t push things, and don’t worry about walking breaks – it’s all about building up that time on your feet.

I had run a couple of half marathons and was in reasonable shape coming into the plan and it was a good rise in intensity throughout. You need to want to do an event like this – I was getting up at 3am to get my long run in before kids weekend sport etc and this was hard. When you combine the plan with the online community through the Marathon Handbook FB page and website, you get complete support. Have used this plan with great success and now looking at upping the pace in the marathon space… GREAT JOB!

Hey dudes, this is the plan to use for a 50 miler. Got me through at least – at age 42, I’m happy with that.
