For some time now I’ve been aiming to do my endurance training at my MAF heart rate. MAF stands for Maximum Aerobic Function, and it’s the heart rate where you’re producing the maximum output without having to use anaerobic systems. Although the MAF formula just produces an estimate, there’s quite a bit of data to back it up.

If you do almost all your training at MAF, you’ll get better (run faster) at that heart rate. The idea is that you first do that, and only when your performance plateaus do you need to start doing any sort of speed work (and then not much of it).

As I say, for some time I’ve been aiming to train at my MAF heart rate, but it’s a low enough level of intensity that I’ve persistently had trouble not running too fast. I have a heart rate monitor, but it’s not very useful during a run, because my heart rate is displayed on my phone, and I don’t want to run around carrying my phone where I can see the screen. The upshot has been that I’ve inadvertently done a great deal of my training somewhat above my MAF heart rate, which rather defeats the purpose.

To get a better grip on my MAF training, I finally broke down and bought another heart rate monitor, which displays my heart rate on my wrist so I can check it while I’m running. It also has an alert function, so I can set it to vibrate if my heart rate goes above some value. After looking around a bit, I settled on the Mi Band 4 (which is available for cheap because the Mi Band 5 is now out). It does the thing I want well enough. (It also does a bunch of other stuff that I don’t care about, and some things that I do care about (sleep tracking), but that I do some other way, such as with my Oura ring.)

After a shakedown run a few days ago, where I spent a lot of time trying to figure out how to use the device the way I wanted, today I went out for a run where I tried to use it for some proper MAF training, and I think I was very successful. I probably only spent two or three minutes (out of a 51-minute run) with my heart rate above my target.

This very easy run was nice and gentle. Sitting here at my computer maybe an hour after I got home, my heart rate is already back down to just 64 bpm, which amounts to a surprisingly complete recover. After a run only a little bit faster, I’d expect to see my heart rate stuck in the 70s for several hours.

Now to see if regular training this way produces the speed gains it is reputed to.

In my continuing coverage of the “digital nomad” lifestyle, here’s the New York Times with a good survey of some downsides: The Digital Nomads Did Not Prepare for This.

“All we could do is sit by the pool or go to the gym,” Mr. Malka said.

Personally, I would be totally okay with that. (In fact, it sounds a lot like what I have right now, except the fitness room is closed and there’s no pool.)

Objectively speaking, autumn is probably the best season. Not cold like winter, stormy like spring, or hot like summer, autumn has great weather—totally aside from the pretty colors and Halloween (arguably the best holiday, albeit in a near tie with Groundhog’s Day).

For pretty much my entire adult life I’ve dreaded the cold dark days of winter, and among the many ways that Seasonal Affect Disorder affected my life in a negative way was that it ruined autumn. I could usually get past the summer solstice okay (although in the back of my head, I knew that the best day of the year had come and gone), and I could keep it together through July and August. But by the beginning of September I knew that winter was coming, and I’d spend the last months of nice weather steeling myself against the dark days to come.

It was the dark that bothered me, more than the cold. It’s easy to armor yourself against the cold—flannel, moleskin, fleece, wool, down—there are many ways to deal with cold. But even a Verilux light therapy lamp (which does help) does not solve the problem of the dark days of winter.

All of which is merely an introduction to saying: Last winter I did not suffer from SAD!

I had meant to write something at the time, but I didn’t want to speak too soon, and then once it was spring, it didn’t seem like the most important thing.

I don’t want to jinx anything, and I’m sure the right combination of stressors on top of the cold and dark could once again put me in a bad place, but something more important has changed than just a good year: I’m no longer afraid of the dark days. Maybe I’ll suffer from SAD again, and maybe I won’t, but at least the mere knowledge that the cold and dark is coming is not ruining my fall! In the back of my head I seem to have turned a corner and developed some confidence that I’ll be okay despite the season.

So what has helped?

First, not having to work a regular job. I’m sorry that I can’t recommend something more generally available, but that was the biggest thing that made a difference. Because I don’t have to be productive on a day-to-day basis, I avoid the depression-spiral that used to result from realizing that I wasn’t getting anything done, which made me anxious about losing my job and being unable to support my family, having the anxiety make me more depressed, and the depression making me even less productive. That used to be a killer. On top of that, because I don’t have to be in the office during any particular hours, I’m able to spend a few of the few non-dark hours of the day outdoors, taking advantage of what daylight there is (and making some outdoorphins).

Second, exercise. I always knew it was important, but I took things up a notch each of the last few years, and each new tick up turned out to provide an enormous improvement in my mood. In my experience, all kinds of exercise are good. Endurance exercise is good. High-intensity interval training (HIIT) is good. Skill-based training—ballet, parkour, animal moves, taiji—is good. Resistance exercise (lifting) is perhaps best of all. Letting the dark days of winter compress you down into a lump that seeks (but never finds) cozy because you’re unable to move? That’s the worst.

Third, community. Granted this is not so easy during a pandemic, but even people that you only see on-line are still people you can have a connection with, and having connections is good.

Fourth, something to look forward to. It can be almost anything. Last year I was looking forward to having my family visit. Other years I’ve looked forward to taking a vacation somewhere warm. Even little things help me—ordering some fountain pen ink or cold-weather workout clothes and then looking forward to the package being delivered, and then looking forward to using the newly acquired item.

Fifth, a project that you can make progress on. Ideally something without a deadline—at least, no deadline during the dark days of winter—but a project that you care about. Something that you can spend a few minutes on every day and see some headway that brings you closer to completing it. Creative projects are good, but creativity isn’t as important as just having a thing that you’re working on, and making steady headway.

Not suffering from SAD, even if just for one year, has been wonderful. Having some confidence that things will be okay-enough this winter that I’m not spending all fall dreading it is even more wonderful-er.

Went out a little fast at the start, partially because it’s chilly and I was cold, but mostly because it felt so good to run a little fast. 🏃🏻‍♂️ Photo from about the mid-point, where I managed to ease it back down a little.
