MAF Heart Rate Training

After reading the articles regarding MAF training (https://philmaffetone.com/want-speed-slow-down/) and with the hope that I can increase my weekly mileage to around 40km per week without injury, I had decided to following this method of training for 3 month while increasing weekly mileage. By following the formula of 180-age as the max MAF training heart rate, I find it very difficult to run at 140 bpm. With my run of longer than 10 km, it is very difficult to keep below the max MAF heart rate without a walking rest.  A few days before end of my 1st month of trying, I came across another article from StrengthRunning (http://strengthrunning.com/2015/02/maffetone-method-and-base-training/).  So, I have decided to deviate a bit from MAF training recommended by Dr. Maffetone by adding in strides (suggested by http://strengthrunning.com/2018/02/base-training-fundamentals/) at the end of the easy run.

Following is my running using MAF method for 1st month (analyzed using http://www.graphmyrun.com/).

From above charts, Jan 23 and Jan 25 runs were with wider spread of heart rate due to slightly hilly routes and I was just learning to run by heart rate.  However, starting Feb, it seems that I can control my heart rate throughout the run better.  The higher max heart rate in Jan 30 run was due to hilly route.


For 2nd month, I have decided to modify the MAF to include strides in the training.

Here's my base training plan in the coming month:-

• Keep the max MAF heart rate as base.
• Add strides at the end of run with max time of 10%, ie. if I plan a run of 40 mins, I will add in 4 mins of strides.  This to ensure 90% of training time is within max MAF heart rate.
• Add in strength training and stretches in my weekly schedule!

The training zones on my first run with strides is as below:-

Still able to keep 90% of time within max MAF heart rate with 20s strides (40 steps, ~ 100m) for 5 times.  Will practice the above for 2 runs during weekday and long run during weekend.
