Running Diary: August 8, 2020/2nd MAF Test

I became lazy for the past days and I just stopped running since last July 30 and that makes 9 days of no running. Three days ago, I came up with a video on my You Tube Channel and the topic “What Happens To You After One Week Of No Running?”. Aside from my personal observations and feelings, I posted a survey question on Facebook about the same question. I got a lot of comments/answers from my friends and from the Public and those comments are mentioned in the said video/episode.

Starting today, I resumed my running and I decided to post my running workout for the day in my blog. This will be a daily routine for me in this blog. Actually, three days ago, I decided to have a run in my Backyard Loop to conduct my 2nd MAF (Maximum Aerobic Function) Test for the month of July. However, on my 3rd mile, my Suunto Watch HR Monitor just stopped and stuck to 113 BPM as average and it could no longer go down even if I was already walking. In a few minutes, I found out that the HR Monitor Belt has no longer have a signal to my Watch. I just stopped and I was able to run and hike for 4 miles.

Today, I did a one mile easy jog as my warm-up with the thought that I am going to do my 2nd MAF Test. My HR Monitor was working and I started with 85 bpm and it registered 112 bpm as soon as I finished my warm-up of one mile. Since I have reached my lowest HR within my range of 112-122 bpm, I decided to start my MAF Test. After my first mile, my HR registered at 121 bpm with a time of 14:25 minutes. I rested for 30 seconds by walking and then I started my 2nd mile. I have slowed at the middle of the mile when my watch registered at 122 bpm and tried to maintain it until I finished the 2nd mile in 16:30 minutes. I rested again for 30 seconds before I started my 3rd mile. When I saw my bpm at 121, I started my 3rd mile and had my pace a little faster. I was able to maintain my average bpm at 122 until I finished my 3rd mile in 14:55 minutes. Having confident of my bpm at 122, I started my 4th mile after resting for 30 seconds. After finishing 2 loops of my Backyard Loop which is equivalent to 0.60 miles, my HR registered at 122 and I was on a “auto-mode” in my run. For the last loop, I was running through perceived effort and I was confident that I was not going more than my 122 BPM. When I finished my 4th mile, I saw my watch registered a time of 12:39 minutes and I was surprised that my time was so fast. But when I looked at my Average BPM, I saw that my HR registered at 123 bmp. I might have run at a faster pace when I was thinking that I was running easy on my perceived effort.

Because of this, I rested for one minute instead of 30 seconds just to be sure my HR will go down at 122 bpm. My rest for 1 minute brought down my average bpm to 122 and I started my 5th and last mile. My 5th mile registered with a time of 15:05 minutes. I just walked for another 300 meters before I did my stretching exercises. In summary, I was able to run a distance of 6.2 miles or 10 kilometers for 1:40+hours.

The rolling is the summary of my 2nd MAF Test (July 2020)

1st Mile—-14:25 minutes                  4th Mile—-12:39 minutes

2nd Mile—16:30 minutes                  5th Mile—-15:05 minutes

3rd Mile—-14:55 minutes

Tomorrow, we will find out if I have improved or not from my 1st MAF Test as we will be able to compare it and come up with an assessment. For the meantime, this is the video that I have posted on my You Tube Channel on what happens when you rest for one week with NO Running. Thanks for watching and please subscribe for more videos on running.




1st MAF Test Of The Year (2020)

After running for six weeks on MAF training, easy running using my Heart Rate Monitor, following the MAF Formula where my beats per minute range would be from 112 to 122 beats per minute must be maintained while I was on my running workout. As a review, Maximum Aerobic Function (MAF) Formula is 180 minus my age of of 68 plus 10 bpm being a runner of more than 65 years old and had never been “sidelined” from running due to injury. My MAF bpm is 122 and my range of MAF Beats Per Minute during my running workout should be 112 to 122. For the past 6 weeks, I was not supposed to breach the maximum bpm of 122 during my easy/recovery runs. However, with my training schedule being a CTS athlete for the past weeks, I have to follow my training schedule and workout as prescribed by my Coach. However, what I have observed was that I was not fatigued in my tempo runs and I could easily recover after a day of hard training.

After two days of not running due to the inclement weather in my Playground, I was fully rested during the weekend and I decided to have my first MAF Test today, June 29, 2020. After a short stretching exercises, I started my run with a warm-up for one mile where my Heart Rate steadily increased from 90 beats per minutes to 112 after my first loop in my Backyard. Before I finished my first mile, I was able to reach 119 beats per minute. Once I finished one mile, I went on on my First Mile for my MAF Test. I finished my first mile in 16:15 minutes where I had to walk for a few seconds after my bpm reached to 123 bpm on the last 400 meter of my first mile. After the first mile, I took a picture of my GPS Watch, take a sip of cold water, and walked a few meters until 30 seconds elapsed (this ritual was repeated every time I finish a mile) and started my 2nd mile. The following is the list of my time every mile:

1st Mile——16:15 minutes                      4th Mile——14:37 minutes

2nd Mile—–15:28 minutes                      5th Mile——14:35 minutes

3rd Mile——14:31 minutes

It was only on the first mile that I breached 122 bpm to 123bpm but it was able to bring it back after a few seconds of hiking. For the rest of the miles, I was able to maintain my average of bpm within 121-122. On my last mile, I was able to maintain the whole mile with an average bpm of 122.

1st MAF Test June 29
My GPS Watch Results For Every Mile On MAF Test

Although my Backyard Loop is not the ideal venue or location for my MAF Test, I am still satisfied with the result of my test and how my body felt after the workout. My body was very relaxed and not so worn-out or fatigued. In my past MAF Tests few years back, I have been doing them on Oval Track, being faster than my time in my Backyard Loop. With the uneven ground, lots of turns, and single-track trail in my Backyard Loop, I expect that my time would be slower than running in an oval track. On the contrary, I think I am faster now as compared when I had my MAF Test in 2011.

After 4 weeks, I will be doing my second MAF Test with the hope that I will be able to lower the times as compared to the results today. I will continue to apply MAF training in my easy/recovery runs in the coming days and weeks. I know that I will be a better and smarter runner in the next months and years due to this training.

180 Formula

Click on the link below on the article by Dr Phil Maffetone on his Maximum Aerobic Function (MAF) which is a detailed explanation on his training philosophy following one’s Heart Rate and the use of a Heart Rate Monitor.


Lately, one of my “friends” from Facebook who had been a triathlete for 17 years had called my attention when he read one of my posts that I am presently training using the Heart Rate Monitor. After his retirement from triathlon, he is pursuing his first ultra marathon run this coming December as he thinks that ultra running is “deeper” and more challenging than his past triathlon feats. I am sure this guy is a “purist” IRONMAN and one of the bests in the 90s or in his younger years. He even predicted that if I continued my plans to get into triathlon in the mid-80s, I could be a sure podium winner in my age category. (Note: I could be fighting it out with my brother Retired General Samuel and Retired Colonel Brigilio Balaba of the Philippine Constabulary for the top honors for our age group).

In one of his e-mails, he shared to me the following updated version of the MAF’s 180 Formula.

Here is the formula:

1. Take 180

2. Subtract your age

3. Take this number and correct it by the following:

-If you do not workout, subtract another 5 beats.

-If you workout only 1-2 days a week, only subtract 2 or 3 beats.

-If you workout 3-4 times a week keep the number where it is.

-If you workout 5-6 times a week keep the number where it is.

-If you workout 7 or more times a week and have done so for over a year, add 5 beats to the number.

-If you are over about 55 years old or younger than about 25 years old, add another 5 beats to whatever number you now have.

-If you are about 60 years old or older OR if you are about 20 years old or younger, add an additional 5 beats to the corrected number you now  have.

You now have your maximum aerobic heart rate, which again is the maximum heart rate that you can workout at and still burn  mostly fat for fuel. Now go out and do ALL of your cardiovascular  training at or below this heart rate and see how your pace improves.  After just a few weeks you should start to see a dramatic improvement in the speed you can go at these lower heart rates.

The details of his e-mail is properly explained in the link below:

Based from the updated version, my Maximum Aerobic Function’s Heart Rate is supposed to be 126 beats per minute (180-59 = 121 + 5 for being above 55 years old). However, since I’ve started with my first MAF Test with a Maximum Aerobic Heart Rate of 121 beats per minute, I will maintain 121 bpm as my training’s MAF heart rate.

Good luck to my ultra running “friends” and BDM “veterans” who will be competing on this weekend’s CAMSUR Cobra Ironman 70.3 Triathlon Competition. Take it “easy” on the swimming event. Make sure to get a “spot” for the KONA IRONMAN this coming October in Hawaii, USA!!! Have fun and be the best to yourself!

For those who have started to train for the 1st Taklang Damulag 100-Mile Endurance Run and for the yearly BDM Races, I highly recommend you to try the Maffetone’s Training on the use of Heart Rate Monitor/MAF Test.
