20 Week Advanced Marathon Training Plan (Elite/Intense)

Our 20 week Advanced Marathon Training Plan (INTENSE) is our toughest and most elite marathon training plan.

It is based on the Advanced Marathon Training Plan, but replaces one of the easy runs with an extra speed work day. This means two days of speedwork per week; 5 days of running, one day of cross-training, and one rest day.

Note: this training program is for people aiming to crush it and reach for the ‘elite’ section. Even if you’ve run several marathons before, this training plan might not be for you. If you’re training for Boston or to truly compete, then you’re in the right place.

The Elite Marathon Training Plan: Essential Info

Who Is It For?:

Ambitious, experienced runners who are looking to train for the fastest marathon of their lives and seriously compete in a race.

Runners who have a good existing running base and want to really push their limits in their marathon effort. Perhaps you’ve already run a few marathons and are looking to set a new PB. You should already be capable of training six times per week, and run 10 miles continuously. 

How Long?: 

Five months // 20 weeks.  

How Many Days Per Week?:

The training program features 5 days of running workouts, plus one day of cross-training – leaving one day of rest per week.

Training Breakdown: What Will Your Weekly Schedule Consist Of?

This plan starts off with a good level of intensity, and continually rachets it up. 

Training Runs are there to add to your mileage and get time on your feet – both essential in any marathon training schedule. These should be done at close-to your target marathon pace; they should be sustainable but requiring some effort.

Pace Runs should be done at your intended marathon pace. If you’re not training for a particular marathon finishing time, you may wish to consider one of the intermediate training plans instead.

Cross Training is there to compliment your run training, and give your legs a break. Cross-training improves your cardiovascular health and strengthens some of the muscles weakened through running, thereby reducing your chance of injury. Recommended cross-training exercises include bodyweight exerciseslight gym work, swimmingyogapilates, and cycling!

Check out our cross training guide for runners to learn more.

 

Intervals are included so you can work on your speed; the method included in this training plan is essentially that of Yasso 800s.   Run for 800m at a high intensity level, where you are uncomfortable, and then bring it right down to a comfortable job for 800m.   Repeat as many times as the plan calls for.

Tempo Runs also build speed; you should start off slow and easy (first 10 mins), then gradually build speed until you are pushing yourself to marathon pace, or to the point of discomfort; then slow down back to an easy run for the last 5-10 minutes.

Long runs should be performed at a slow, conversational pace – don’t worry about speed when doing your long runs, focus on getting the hours on your feet in.   If you try and do your long runs at marathon pace, you’ll end up overtraining and getting fatigued.   If in doubt, run the long runs at 60 – 90 seconds per mile slower than your planned marathon pace.  Note that the training plan includes 3 x 20 mile runs to really solidify your base.   Anything over 20 miles really just increases the risk of burnout.

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!

Well, I have been marathoning for almost 15 years and wanted to test something new out. I tried this plan because it looked completely different than any training method before. It didn’t make sense how the running peaked, and I got to the start line exhausted and sick, clearly under rested. The marathon had actually gone pretty smoothly until mile 17, when my ankle rolled and my ACL ripped. Had to quit the race and was upset with this training plan. However, free IS free. 6/10. Would not recommend

These running plans are AMAZING. I used it for 2 half marathons and I was so surprised at how I gained fitness, even though I was ill for 2 weeks and sustained a knee injury!

I completed the half marathon in 1h37 min 😃🤗

Thanx again team!
