Quite a Week!

Owl’s Nest Book Launch – Calgary

On Wednesday, February 7 we held a book launch event at our favourite local indie book store, Owl’s Nest Books. Sarah Pratt, the Events Director at the store (and an avid ultramarathoner) was our marvelous host for the evening.

We were thrilled to welcome a standing-room crowd of friends, neighbours, teammates and work colleagues. I was honoured that my neurologist (Dr. Demchuk) and my long-time teammate at Adrenaline Rush Athletics (Dr. Stephen Wood)… both heroes of my stroke story… joined us for the evening.

I did a short reading from Stroke of Luck: My Life in Amateur Athletics. During the lively Q&A portion of the program, I shared my main messages:

  • the importance of an active lifestyle
  • knowing ALL the signs of stroke
  • raising awareness (and funds) for the world-class stroke care provided by the doctors, nurses and staff in the Foothills Stroke Unit

Sincere thanks to Sarah at Owl’s Nest Books and Jeremy Deere from Strides Running Store, for your support of the reading and running communities in Calgary.

It was a special evening!

First Half Marathon – Vancouver

We didn’t get much time to recover, as we headed off to Vancouver on Friday for a weekend visit with Matthew. The headline purpose of the trip was to participate in the annual First Half Marathon, put on by RunVan and sponsored by BlueShore Financial.

As usual, the race was outstanding. It sold out immediately, as it does every year. This is definitely one of the premier races in Canada; well-organized and perfectly executed. It doesn’t hurt that the scenery is second to none. The highlight is the lap of the Stanley Park seawall.

I wrote about my history with the race in a previous post. This year, our race was challenging. The weather did not cooperate, although the steady rain was little more than an inconvenience. Deb and I were both hobbled by nagging injuries, which affected our preparation. While it is often true that one can run through these things on race day, neither of us was so lucky this time.

The second half of the race was a slog. The good news is that we got through it. The finish line on Drake St. in Yaletown is always a welcome sight. And who cares if we were a few minutes slower than last year?

…and a bit of street photography

I always look forward to walking the streets of Vancouver, armed with my discrete camera, the Ricoh GR III. It is the perfect camera for street photography.

Here are a few samples of the photos from the weekend.

Photo Run – Big Game Edition

Our long runs along the Bow River often take us past the Centre Street Bridge. It’s an imposing and historic structure, and in good morning light photo ops are plentiful. As we ran under the bridge last Sunday, I made a note to take a closer look at the lions that guard the four corners of the upper deck.

Fortunately, we ended up back at the bridge towards the end of our run. I welcomed an excuse to stop at that point. Deb was keen to do another kilometre. “Good for you”, I told her, “but I’ll be here checking out the big cats.”

The morning light was strong and contrasty. From the pedestrian ramp, I got a couple of nice shots of the southwest lion. The statue looked great (regal, actually) with a monochrome edit in Lightroom.

Centre Street Bridge, Southwest corner (January 28, 2024)

I decided I would return in a couple of days for a photo run and a closer tour of the lions. In the meantime, I did some research into the history of the statues.

The original lions were commissioned in 1916, along with the bridge. They were modelled after bronze lions that guard Nelson’s Column in Trafalgar Square in London. The Calgary copies were cast in concrete by one James Thomson, a city employee. They each weigh 12,600 kilograms.

By the 1990s, the statues were in a state of significant deterioration, due to decades of Calgary weather cycles and vibration from bridge traffic. In 2000, city council directed the repair and conservation of the southwest lion. It also directed that the same lion be used as a template for the construction of four new statues. The restored lion now sits on display at Calgary’s municipal government building. The original northeast cat was repaired and conserved. It was relocated to its current location in Rotary Park in 2018.

With that background, here’s more on my photo run.

I went late in the afternoon, hoping for an interesting chinook sunset. We’ve had a lot of those lately. Would I get lucky? Yes and no.

I started my run in Rotary Park, so I could see the repaired northeast lion up close. It’s the only statue to have been returned to the bridge, and it commands a perfect spot at the south end of the park, overlooking downtown.

I navigated the ice and mud around the statue. I snapped a few shots, but none of the compositions I tried were very satisfying. I might have had better results with a wider focal length lens instead of the 28mm Ricoh GR III. No problem… this was supposed to be a run, so I moved on.

I jogged along the crest of the bluff for a few minutes and enjoyed the vista, then headed down towards the bridge. When I looked back up the hill, the lion was bathed in the low, setting sun. I knew I had only a few minutes before the light changed, so I scrambled back up the muddy pathway to a spot just below the lion. I snapped one shot. The light was amazing, and I think the result was good. It was by far my best shot of the day.

I continued down to the bridge and did a short loop around Chinatown. I was rewarded with a few worthy shots before I made my way back up the bridge on the west side. It had been a while since I ran up this hill… yes, it’s still tough!

Prosperity Bar (January 30, 2024)

As for any more shots of the lions on the bridge, the fading light was quite flat and uninteresting by that time. There was a bit of chinook magic going on though… so I worked with what I had!

There was also the challenge of getting a good perspective on the statues and the other details on the bridge (like the medallions that recognize the distinct influences in Calgary’s past… see the example below) while being confined to the sidewalks that pass underneath the statues. I suppose a drone would have been a nice accessory for this shoot, but that’s not my thing.

Here’s one of the small details on the bridge: medallions on the side of the “kiosks” that serve as the base for the Centre Street Bridge lions.

There are roses for England, shamrocks for Ireland, thistles for Scotland, and maple leaves for Canada. And bison heads to represent the west.

In the end, I managed to get a few shots of the “big game”. But maybe the best result was the realization that I left many good ones on the bridge for another day.

Prairie Mountain Sunrise, Part 2

The Science

NOTE: This article was updated in January 2026 to correct errors and expand on some of the concepts.

After we returned to Calgary from our December 29 Prairie Mountain sunrise hike, I started to wonder about the small anomaly that led us to pick that day. Specifically, the fact that the day with the latest sunrise does not align with the winter solstice in the northern hemisphere. Before I get into the science, here’s another photo from that memorable morning.

Looking northwest from the summit (December 29, 2023)

I did some research and learned the interesting astronomical reasons for this phenomenon. I first looked up the sunrise/sunset tables for southern Alberta. The solstice occurred at8:27 p.m. on December 21, but the latest sunrise occurred more than a week later. Not only that, the date of our earliest sunset was well before the solstice—way back on December 12, to be exact. 

What’s going on here? After all, these differences are not small. 

While it’s true that the solstice is the shortest day based on sunlight hours, it isn’t the shortest solar day, which is defined as the measured time for the sun to pass over a given meridian line from one day to the next. In fact, solar days are the longest in December. It’s important to note that solar days are not the same as clock days, which are the familiar 24-hour periods that we measure with our timepieces.

A recent article in Scientific American explains that there are two reasons for this counterintuitive result. With all credit to the excellent minutephysics video by Henry Reich (“Why December Has the Longest Days”) referenced in the article, I’ve reproduced the two reasons in the following chart.

First, the shape of the Earth’s orbit is not a circle but an oval, an ellipse. The difference between the earth’s nearest and farthest points from the sun is small, about 3 percent of its average orbital distance of 150 million kilometres. This matters because as the earth reaches its closest point (called the perihelion), it moves faster through space. This faster movement lengthens the solar day—again, that’s the time needed for a given line of longitude to come around the next day to align with the sun. This effect adds about eight seconds to the solar day.

Besides the eccentricity of the earth’s orbit, the tilt of its axis also contributes to the disparity between solar day and clock day. This effect, called the obliquity effect, lengthens the solar days by about 20 seconds around the solstices and shortens them by about 20 seconds around the equinoxes.

The impact of these two factors on the solar day is well known. There is even an equation of time to relate solar time to clock time. Mathematically, the effect is represented by two sine wave functions. The frequency of the eccentricity curve matches the earth’s annual rotation, and the tilt curve goes through two cycles each year. The figure below was generated on PlanetCalc. It shows how adding the curves results in solar days that are shortest in February and longest in December. There is also a smaller peak in the spring and a dip in the summer.

Source: PlanetCalc Equation of Time calculator for 2024

Because perihelion occurs close to the winter solstice (on January 2), the two day-lengthening effects are additive, totalling about 30 seconds a day at the peak in November. These “extra” seconds are pushed forward to subsequent days, making solar noon (the precise time that the sun reaches its highest point in the sky each day) later and later at that time of the year. And because sunrises and sunsets are symmetrical around solar noon, we get the observed result: the earliest sunset gets shifted backward (before the solstice), and the latest sunrise gets pushed forward (after the solstice).

As a final point, if you were to do an experiment in which you marked the tip of the shadow cast by a sundial each day at precisely noon, it would trace out a unique, elongated figure eight shape over the course of a year. That shape is called an analemma, and it is a graph of the equation of time. Changes along the vertical axis of the curve are due to the tilt of the earth (cycling between -23.5 degrees to +23.5 degrees), and changes along the horizontal axis are due to the eccentricity of the earth’s orbit.

The figure at left is the analemma plotted at noon GMT from the Royal Observatory at Greenwich, England (Source: JPL Horizons Lab). I like this figure because it includes calendar notations, which make it easy to compare with the equation of time graph shown above.

Whew! I expected the answer to this question to be simple, but it’s taken me a few tries and a lot of soak time to understand. Somehow it seems appropriate, having just started a new year (and passed the perihelion), to recognize that the universe is full of mystery.

Until next time,

Prairie Mountain Sunrise, Part 1

My friend Tim can always be counted on to organize good outings. A coffee, a lunch, a hike. He organized our excellent excursion to Pocaterra Ridge in September to see the larches.

One of Tim’s good ideas in the last few years is a sunrise hike to the summit of Prairie Mountain in Kananaskis. He’s been considerate enough to arrange the hike on the day with the latest sunrise. This year, that day was December 29. Before the hike, I didn’t independently verify Tim’s assertion on this point. More on that in Part 2 of this post. But I did enjoy the extra two minutes of sleep that I was told would be available by delaying our hike from the winter solstice by eight days. 

Dan and I joined the convoy that left Calgary at 6:20 to reach the trailhead by 7:10. A testament to the popularity of Tim’s idea is that our group was ten this year, up from five last year. Mind you, last year’s -20C temperature may have been a contributing factor. (I passed on that one.)

The hike was great. It was my first time on the new and improved Prairie Mountain trail. It’s now 8.4 km with 711 metres of elevation gain. The modifications evened out the trail’s steepest segments, added some Lawrence Grassi-like stone steps in a couple of places, and widened the trail. Even in the dark, lit by a headlamp, I liked the changes. I’m not a PM veteran or a mountain goat. I have done the hike maybe six times, in various weather conditions. And I’ve been in a couple of slippery situations on the old trail that left me wondering if we’d taken a wrong turn. It just never seemed safe to me. Now it does. 

We may have been a bit late getting started. The southeastern sky was already lit with beautiful shades of pink at the first viewpoint. We hustled onward, knowing that if we could get onto the summit ridge we would see the sun break the horizon. Our time for the ascent was about 75 minutes. 

We didn’t have long to wait once we reached the 2,210-metre summit. The light display was stunning. Sunbeams streamed around a lone cloud that was parked just above the horizon.

I had my Ricoh GR III with me. (Yes, I know, I say this often, but I really love this camera!) We snapped a few group shots as the sun made its appearance.

To the northwest, Moose Mountain was glowing, with snowy highlights and a rosy sky above.

We enjoyed the vistas and took more photos. As I reached for a snack, I realized that my fingers were freezing. It was deceptively cool, but thankfully the summit winds were moderate. That isn’t always the case on Prairie. We started down, trading our headlamps for sunglasses.

On the descent

An enjoyable coffee and treat at the Bragg Creek Cafe & Baking Co. rounded out the morning. 

Happy New Year to all!

December Run Streak, Non-festive Edition

The month is almost over, and that means the end of the Strides Run Streak. Looking forward from our December 1 start, the task seemed daunting. But here we are, already closing in on January. The persistent pattern of warm weather and the relative absence of snow in the city this year have certainly made our task much more bearable. Even so, I don’t mind saying that I’m looking forward to a day off on January 1.

Now that Christmas is in the rear-view mirror, I felt I should do a follow-up post to my last piece. That one was my attempt at a (slightly) festive piece, in keeping with the season.

This time, I feel I can loosen up the constraints. The photos in this post were all taken while out for one of my December runs. They were all taken with the incomparable Ricoh GR III. However, the subjects are less “Santa” and more “street”. These are subjects that fall closer to what I might normally look for when I’m out and about with my camera.

So, with no explanatory text, I present… my December Run/Photography Streak, non-festive edition:

Let me know what you think. I haven’t seen much in the comments section lately.

Until next time, Happy New Year!

In closing, I’ll mention that my book, Stroke of Luck: My Life in Amateur Athletics, will be available on Amazon for a special resolution sale price, starting in January. Thanks to everyone who has already picked up a copy. It’s been great hearing your thoughts on the book.

Streaking through December

The pressure has been building for three weeks already. It’s nothing serious, mind you.

For the last few years, the arrival of December has meant the start of the Strides Run Streak, hosted by our wonderful neighbourhood running store. The parameters of the challenge are simple: run at least a mile a day for the full month. It’s wildly popular with the locals, including Deb and I.

I do have some history with this challenge. In 2012, I started running on December 1 and turned a one-month goal into a multi-year streak. That particular streak, which didn’t end well, isn’t the point of this post. You can read all about that adventure in my book, Stroke of Luck: My Life in Amateur Athletics. (By the way, if you hurry, you can still get your copy in time for Christmas, either at Owl’s Nest Books or directly from me. Thanks to all of you who picked up a copy. Much appreciated!)

This year’s streak has brought the usual mix of weather and physical challenges. Pathways have been notoriously icy. I’ve been dealing with a nagging calf issue lately, which fortunately seems to be on the mend. It’s looking promising that I will get through the month.

As has become my custom, I’ve added to the challenge with a photographic element. I look for a memorable photo during each run. That can be a tougher goal than the run itself, but equally rewarding. I’ve been giving my trusty Ricoh GR III a good workout. That camera is amazing!

I like the idea that I don’t know what I’ll see when I leave the house. I have a built-in incentive to explore other neighbourhoods (or even my own) with the idea of finding fresh photographic subjects (and good running).

If I’m totally honest… and I think my readers would want me to be… I feel that the results this year have been something less than stellar. Or maybe it’s just that my subjects haven’t been leaping out at me. I think my muse may already be on holiday. But as always, I find if I keep my eyes open and trust my instincts, I will be rewarded with some surprises.

Lines in the sky, Glenmore Athletic Park (December 2023)

I try not to fall into the trap of snapping easy targets, like excessively decorated houses. Yes, that is a small, self-imposed constraint that makes my daily task a little tougher. That said, I find that even if some light displays don’t compare with Clark W. Griswold’s, they are still worth photographing.

Merry Merry, Altadore (December 2023)

My 2023 SRS photos may not be totally traditional, at least as defined by seasonal expectations, but when I look at them as a whole they seem to evoke a rather pleasant feeling. Is it hopefulness? Calm? Wonder?

I’ll let you decide for yourselves. I’m keen to hear from you, so do leave a comment.

Looking slightly festive, Beltline (December 2023)

Signing off for now, I’ll say Merry Christmas. Until next time, I wish you happy running, shooting, or whatever your particular passion is.

Be well and enjoy what’s around you. Peace!
