Your Running Shoes in Cost per km or Mile you were a runner, you should stop reading this and just accept my apology for having planted the thought in your head. It’s a terrible thought to have on your mind while you’re running, and even if you were not, so please try to get it out as soon as you can. However, it’s an interesting way to look at one aspect of one’s running, the cost of running shoes per km or per mile ran from what you paid for them, and what you got out of them if you tracked it (or have something like a Garmin and Strava app track it for you). You can get the final answer in the end, but probably an estimate from experience and/or history if you’ve been running for long. It’s an interesting thought, but not a pleasant one if every time your Garmin or fitness watch buzzes or beeps for a km or mile, you’re basically putting money in a toll machine based on your calculation!

My 100 Mile Running Week Experiences“How many hundred mile weeks do you run a year?”

That was the question I got asked most during a tour of the 2000 Vancouver International Marathon’s elite athlete reception that my elite running friend from Nova Scotia, Smartex Tambala, had taken me to out of his kindness. To be fair, a lot of the elite marathoners in that room got asked that as well, almost like the standard greeting to ask to start conversations, but the reception wasn’t just for the elite athletes. It was also for their friends, family, and other guests, of whom I was one courtesy of Smartex. However, I seemed to have looked the part enough at 5’2″ and about 102 pounds that the other elite athletes risked being wrong about me not being one, rather than potentially insult me by assuming I wasn’t elite athlete material. It’s been the only instance in my life where I had been presumed that way rather than the opposite. And as ridiculous as the question was for me at the time, peaking at maybe half of that mileage weekly, it stayed on my mind long enough to be a psychological itch I ultimately had to try and physically scratch.

What’s the Cost of that per Hour? A Simple Guide to Assess Value

We basically consume things as we live. As one simple way of assessing value when deciding whether or not to buy something, I calculate the price I’ll pay for it by the hour and put it in context of some other things to see how it stacks up. It’s a simple assessment of what the price is, divided by much time it could take up in my life, and compare to something else.


A new tablet. $300, use, on average, over half an hour per day for two years. That’s $300 for at least 365 hours. For simple math, I go for 400 hours so $0.75 per hour. Compare that to a movie without extras that’s about $5 to $7 per hour (Canadian prices). High speed Internet at home that is about $0.50 per hour for me. A full sized piano keyboard that’s currently at $2 per hour. Current four years old desktop that is going under $0.50 per hour.

The call to buy or not is arbitrary pending other factors I’ll go over below, but this gives me a lot of context. I go for it but I commit to keeping that tablet for at least 2 years (and I recall this if I get a new one sooner than 2 years).


Other considerations

Of course, other considerations must be taken into account for the calculation:

  1. Use with other things. I may not use my tablet at all times without other things like app purchases. That’s fine. Calculate the other things for what they’re worth. Nobody ever only consumes one thing at all times in their lives.
  2. What else can you get for the same or better value that you might want to get instead? This often stops me as I opt for some other thing.
  3. Compare similar things. This is valuable for new, rare and/or unique things, especially the costly ones like those on vacation. For such things, compare what you can imagine in looking forward to the thing or experience, and compare it to something similar in theme (not necessarily same sort of thing because unique stuff is hard to find similarities for comparison). For considering things or experiences you were purchasing again, ask if that was worth the money at that rate.
  4. Stuff you can’t calculate. There is a lot of things you can’t calculate, like the social value to make new friends, or see some person you’re interested in getting to know better among a group of friends at a movie, that can overrule, or be worth the value of the something more costly, or novelty of a new experience that could lead to more things, a fun memory, etc. That’s great! Go for it! Just keep the total in check for what you can afford in your life. That’s a bigger calculation that’s not actually hard to estimate, but you’d need to know some details about how much you spend, save, want to save, etc. Keeping enough financial data about yourself is the hard part there, but I have that to help me.
  5. Other things still. Whatever you can dream up to consider, whether to overrule or help make the decision more systematic and rational. Sure, add it in! It is your calculation!
  6. Go with your guts if all else fails. As stated.


It’s far from a perfect system or model for deciding whether or not to buy things, but for starters, I think it’s a damn good one!

The Golden Tempo is 97 BPM (beats per minute)

Is there a “golden” tempo that is universally appealing, like the Golden Ratio is universally appealing visually? Not to my knowledge… nor search engine Google’s knowledge, for that matter. However, as I was setting a tempo for a piano étude I had composed a few decades ago, it turned out to be about 100 bpm. That was roughly 1 and 2/3 beats per second, or 1.666 approximated, which wasn’t far from 1.618 approximated that I knew to be the rounded value of the Golden Ratio.

If You Can’t Give Students Zero, Give Them 1 or 0.1 Per Cent

In September 2012, Lynden Dorval, a physics teacher in Edmonton, Alberta, Canada, was fired for giving students a mark of zero for work that wasn’t handed in or tests not taken (CBC). It went against the school’s policy of not giving students zeroes, apparently, at Ross Sheppard High (and I’m sure at some other schools around the world).

Well, talk about STUPID school policies!
