“Chains of habit are too light to be felt until they are too heavy to be broken.”

Warren Buffett

I’ve got a habit. I walk, hike and run a fair amount every day. Perhaps my favorite activity is to hike – at some speed between a trot and a gallop. I also love numbers and have used a pedometer to keep track of my miles walked each day for the last ten years: 2012 to 2021. I made spreadsheets each year and have looked at the data trends over each week and each month of a year. This is an update from my previous post Quantifying Hiking and Running Part 1 with eight years of data.

Thus, I have now accumulated ten years of walking data:

Table 1: Yearly Mileage

2021	3001	63
2020	4347	62
2019	3174	61
2018	3387	60

2015	3117	57
2014	3008	56
2013	2634	55

Table 1 shows the sum of my walking (in miles) for each month of the last ten years:

I also like to see the cumulative amount I have walked each month over the course of a year. Table 2 summarizes my walking progress each month over the course of a year:

												31182	Total

The total over ten years is 31,182 miles or 50,186 km. That’s an average of 260 miles or 418 km a month.

A few things worth pointing out:

First, I had my biggest walking year in 2020 – during the COVID pandemic I walked 4347 miles (6996 km). The reason for this high mileage was I entered the Great Virtual Race Across Tennessee 1000K race. In this four month long virtual race, I covered 1907 miles ( 3069 km) from May through August. Another way I covered miles in 2020 was by walking and running every street in my town. One reason I covered many miles was to see what it would be like to hike the Appalachian Trail – a goal of mine that I thought I might do in 2020 or 2021.

Next, for six years I covered was in the 3000 mile (3001-3387 mi; 4829-5451 km) range. I first broke 3000 miles in 2014 and again in 2015. I was able to cover more than 3000 miles again from 2017 to the present. I started trail running in 2017. I was able to complete the Badger Mountain 50 mile race; it was slow and steady. Another 2017 challenge was finishing the Issy Alps 50k, that was far tougher than the Badger Mountain race for me.

In 2018, I tried twice to run 100 mile races: Badger Mountain 100 (69 miles) and Bryce Canyon 100 (81 miles). While I didn’t complete them, I learned much. I still think I may do a 100 mile distance,, however, my current thought would be to walk rather than run. From 2017 to the present, I have had some great hiking, fastpacking and backpacking adventures with my friends.

My favorite year was 2015. I achieved no major milestones in running, backpacking or hiking. What I did accomplish was to recover from surgery on my esophagus to treat achalasia, a rare disease that I have. Achalasia has been a challenge for me. There is no cure or much known about the disease. Thanks to the work of my medical team, lead by thoracic surgeon Dr. Brian Louie, I was able to return to a vigorous life. My view going forward after my January, 2015 surgery has been “carpe diem, quam minimum credula postero” (“Seize the day, put very little trust in the future.”) As an achalasia patient, I am grateful to be able to explore the world by covering as many miles as I can.

I had some low mile years. Why? For 2012 and 2013, the answer was full-time work got in the way of walking. I was able to retire from full-time work in September, 2013. I did some part-time work in 2014 and 2015 as well as attending college to learn biology, From 2016 to the present, I have been active in volunteer work at some non-profits but have much more time to spend outdoors.

My worst year was 2016. It wasn’t the lowest mile year but it was the most annoying. I kept injuring my right knee, then my right hip, then my left knee, then my right knee. I think there were two things that caused these problems. I was running a lot on hard surfaces ( I was training to run the Philadelphia Marathon with my brother). More important, the muscles of my right knee were much weaker than my left knee – which I figured out with the help of my doctor in December, 2016. So, after 2016 I minimized running on hard surfaces, started strength training and switched from cushioned shoes to zero drop trail running shoes. The important lesson for me: Avoid injuries if you want to cover miles.

Figure 1 illustrates how I’ve done over the last ten years. The bottom set of points are from 2012; my lowest mileage year. The top set of points are for 2020; my highest mileage year. There are three sets of data in a range in between the lowest and highest. These are years 2018, 2019, and 2020.

I want to write in the future about my daily tracking methods – many times the fact that I was behind my goal got me motivated to do more miles. What I do every single day is how I cover many miles in a year. Another useful topic is how walking has affected my health; in general it’s been very positive but I ought to write my lessons learned.

Let me close by thanking all my friends and family who have put in miles with me. I always enjoy the company; hopefully you do as well. Of course, sometimes I have an excessive number of words per mile! Well, I have to dash off now; got a few miles to cover today.
