Seriously

As I was leaving my apartment complex's recreation centre this evening, a man going by saw me unlocking my bike from a tree, putting it on the pavement and switching on the lights. "You still riding?" he asked.

"Well, yeah!" I answered.

"Seriously?" (He said, incredulously.)

"Definitely!" (I said, brightly.) "All year."

What I didn't say, and thought of about three seconds later:

No, in the winter I just take the bike out into the parking lot so it can pee.

Why it's so much harder in the cold


I rode down to a friend's place in Chinatown yesterday to go snowshoeing. Packed the snowshoes into the panniers and headed downtown. But it was sludgy, hard work. I got ice in my eyelashes and I kept getting my throat uncomfortably clogged because I was breathing hard and it was -30 out (or something like that). It just felt like I was towing a refrigerator (except without the welcome extra boost a refrigerator might have given me on the downhills). I kept checking to see if my back tire was flat, it was that hard to pedal. And by the time I got to my friend's place I was trembly-tired and my lungs were killing me. 

And, unfortunately, I'd been sweating, thereby soaking my wool base layer, which meant I started shivering as I cooled down in my friend's car on the way to Gatineau Park. (That is something to seriously, seriously think about when biking in the cold: when you stop, do you have a change of base clothes, or long enough inside to dry out before you have to go back outside again?) 

But, happily, I got myself nice and warm again pretty fast with a vigorous snowshoe up about 150m of vertical gain, then a moonwalking romp back down all the steepest bits.


Anyway. Why, oh why, I thought to myself, is it such hard work to bike in the cold? It's not just me: a friend of mine quit biking when it got really cold last year because it was such hard going. So I went out looking for answers. 

According to Lennard Zinn at Velo News, air resistance actually plays a part: as an aerodynamicist he consulted says, "Temperature has a much more pronounced effect on air density than humidity: cold air contains more molecules per cubic meter." Another points out that "The drag you experience at 25 degrees Fahrenheit is about 10-percent greater than you would experience at 75 degrees Fahrenheit. This is approximately equivalent to the difference between riding at 20 mph and increasing your speed to 21 mph." 

So at -40F? Eek. 

Add to that what I found out at Fit Werx: tire rolling resistance is lower in the cold, making your tires sludgy. "Tire rolling resistance measures how much energy it takes to roll your tires over the pavement. When a tire contacts the ground it deforms and then springs back to its original shape. Every time this happens energy is lost in the form of heat. A warmer tire has improved elasticity and will lose less energy during this contact with the pavement."

The folks at Icebike also agree with my friends' theory that colder grease & bearings will affect you as well, making it harder for the whole drive train to turn, thereby making you suffer. (And look! a website devoted to winter biking! Hooray!)

Then there's the psychology: the way your scarf and jacket and hood and hat and helmet all combine to make it more or less impossible to turn your head to shoulder check. The only turns you can manage look a bit like Michael Keaton's Batman: shoulders and neck and head as a single molded-plastic unit. That just adds to your feeling of clumsiness and lumbering. And there's the sore lungs (after a pretty high-activity day yesterday, my lungs still feel just slightly sore from all the work in the cold air).

But. BUT. I was riding back home from my friend's place yesterday, after dark, down Bank Street through the Glebe, and as I went past a cluster of bundled people standing at a bus stop, I heard one of them say, "Nice!" and threw him a grin. Sure, I had to downshift, a lot, to get up that mile-long hill before my house. But I felt pretty badass when I got home.

The year of circumstances (not being quite right)

I'm trying to do a new year's reflection on all my blogs: a sort of recap and recalibration.

But this year, circumstances have been such that I don't get on the bike as much as I did. I used to have a job five days a week that was about seven or eight miles away depending on the route you took, and I could ride there in the morning and ride home at night, and I spent a lot of time with my legs going and my eyes on the path in front of me, or my head up and my ears tuned for the cars.

This year, though, I've been driving three days a week to a job 40km out along the highway: not something I can bike to. Well, I could. Sure, I could. And would I ever be in amazing shape right now if I did. . . But it's a matter of time. I don't have that kind of time. If cycling was a fitness thing for me, if fitness was a lifestyle for me like it is for some, then sure. I know there are a lot of people that ride that far to and from work. But I just can't take that much time out of my day. (And, leaving that job at 7 or 8 at night would have me riding home in the dark all the time, along back roads in Quebec. No thanks.)

But, one thing I've learned because of that is how much I actually do enjoy riding when I can. I'm no longer just getting up and riding to work in the rain or the snow or the heat because that's how I have to get around: I'm relishing the chance to go downtown now on the bike. No searching for parking. No digging for change to pay for parking. No running out to feed the meter. No stopping for gas, no scraping off ice and brushing off snow and not being sure if the car will start because of the deep cold. The bike starts, no matter how cold. I can store it inside. It costs nothing to park and it never needs gas or wiper fluid.

This winter has been snowy (very snowy!) and cold: not the best conditions. But I still get out on the bike. I still relish the feeling of being one of the (growing number of) cyclists who just bundle up and get out there, and who try to explain to their friends why riding is actually warmer than walking, or taking the bus. And my long term job searching goals now include the nice-to-have of being within biking distance: because I know (for reals) now how important it is to me.

Beautiful icy night

The cold snap has really been amazing this winter. The snow came down and stayed - deep and fluffy - and for the last few days, temperatures have been in the effective -25 to -40C range. In fact, December came hurtling in on a wall of snow and hasn't really shown any signs of letting up on the full-on, good-old-fashioned Canadian weather.

It's great.

I haven't been on the bike nearly enough these last few months. Between a part time contract that's inaccessible by bike, another part time contract that is often more efficient if I do it from home, a bunch of personal commitments and pressure, and weird hours, I've found myself more and more having to use the car. And it's been driving me nuts. Then on some days when I could use the bike, there's been 15 cm of fresh snow down and nothing plowed yet, and I've been off the bike enough lately that I'm uncertain of my snow skills. It's been a pain.

But today I woke up and it was an effective -39C outside. I was supposed to take the car to the shop for some work, but when I tried to start it, it made a wheezing noise and rolled its nonexistent automotive eyes at me, as if to say, "Seriously? NOW?" (13-year-old diesel engines don't take kindly to subzero temperatures.)

So I rescheduled the appointment, called my employer and said I'd work from home, and settled in. But this evening I had a meeting to get to. Knowing the car wouldn't work made it that much easier to decide on the bike. I wheeled it out to the elevator and was surprised to realize I was actually a little excited. This was going to be, believe it or not, my first real snowy ride since the hammer came down at the start of the month. (That's how bad my bikelessness has been.)

The temperatures had soared to a balmy effective -25C. (-18 real temperature and a wind chill of -25.) There was dusty, sparkly snow falling. As I stood in the lobby tying my scarf and pulling on my mittens and turning on all my lights, a guy in his twenties came in the front door, saw me, and said, "Whoa, ride safe!"

"I plan to," I said, and then I got myself bundled up and carried the bike down the steps to the snowy pavement.

And it was probably the best ride I've had in months. It was so cold it was dry, with a thin layer of snow down on the streets that didn't affect traction at all: there was fine snow coming down. The streets were pretty empty, and the drivers that were out were taking it easy and going slowly, having been scared straight by all the black ice this morning, perhaps. They were giving me a wide berth, driving carefully and courteously, partly because with all this snow down I pretty much have to take up most of the right hand lane, and partly because they're aware of the treacherous conditions. I wish they drove like that all the time, it would be fantastic.

One advantage to all the driving I've been doing lately: I know what's going through a driver's mind when they come up behind a cyclist on a snowy night, and I've watched how other drivers act. It made me more certain that they weren't likely to buzz me or drive aggressively. I've watched a lot of my fellow drivers slow down and move into the other lane to pass cyclists in the snow.

And I also knew to have an enormous taillight and a turtle light on my helmet and a big headlight on the handlebars; because I have cursed at a distressingly large number of cyclists this winter who I've come across biking along on a snowy road, unlit and wearing black. Some of them have really scared me. So, I was lit up like a Christmas tree, and feeling pretty safe as a result. (Also, cyclists: please, please, please, my driver side can't stress this enough: get lights.)

I whooshed along to my meeting without a single slip, or slide, or startle, thoroughly enjoying myself with the cold and the snow and the dark and the self-powered swoosh, and realized part way there that I was actually almost too warm (with my merino base layer and my sweater and my Thinsulate mittens). On the way back, it was just as lovely: cars giving me space, the cold air on my face, my tires cutting along through the thin layer of snow on the street.

Why wouldn't you bike in the winter?

Sousveillance nation

Sousveillance (/suːˈveɪləns/ soo-vay-ləns; French pronunciation: ​[suvɛjɑ̃s]): most commonly defined as the recording of an activity by a participant in the activity typically by way of small wearable or portable personal technologies.

Lately I've started to realize just how many people are riding with cameras on their helmets or handlebars. Yesterday, my Twitter feed blew up over a video on YouTube of a cyclist being ticketed (back in June) for taking up the whole lane at a pinch point. (The #ottbike hashtag went a little nuts with tweets to and from pretty much every officially-tweeting Ottawa Police Service representative.)


The cyclist fought the ticket successfully, I assume because the city's own website says:

Cyclists are required to ride as close as possible to the right curb of the roadway, except when:

  • Travelling at the normal speed of traffic
  • Avoiding hazardous conditions
  • The roadway is too narrow for a bicycle and a motor vehicle to travel safely side-by-side
  • Tiding alongside another cyclist in a manner that does not impede the normal movement of traffic
  • Preparing to make a left turn, passing another vehicle, or using a one-way street (in which case riding alongside the left curb is permitted) 
Well, I'd call that pretty clear. . . the first three are clearly demonstrated in this guy's video. He's going at the speed of traffic; the potholes are terrible; the road's too narrow to share.

Cyclists, increasingly, are getting cameras, and they're doing it to defend themselves, primarily, maybe with a side helping of educating the public. It's a lot like the dash cam situation in Russia, where because of insurance fraud and corrupt police - and because the courts prefer video evidence to eyewitness accounts - a huge number of drivers are recording everything that happens. Having a dash cam can actually lower your insurance premiums in Russia, I understand. (Bonus: you might get some truly crazy footage.)

Cyclists are in much the same position: if  you're nearly right-hooked, or passed too close by a heavy truck or a bus, or when you're given a ticket for taking the lane when there was reason to do so, it's way better to have evidence rather than your subjective opinion. I can't count the number of times someone's done something dangerous around me and it all happened too fast to identify the car or the plate number, and good luck catching up to a car to get that information. Then, if you actually want to make a complaint, you're stuck with how it felt to you, which isn't as concrete as camera footage.

So cyclists start recording. Some cameras record for a set amount of time, then loop, so you can 'set it and forget it,' and only pull the footage if something happens. You're just always recording, every time you roll out there onto the road. Clip on your helmet, kick your leg over, turn on your camera, and step on the pedals. It sounds a little crazy to me, but also like a recognition - that camera's part of your safety system, like your lights and bell and helmet.

YouTube channels like BikeViewCA are full of video clips demonstrating close calls, dangerous stretches of road, and confrontational drivers. (There are also clips showing beautiful days and exhilarating rides, but they're outnumbered.) And it's getting so that non-cyclists know about the cameras, too: there's this angry driver who sees the helmet cam and shouts, "Yeah, I hope you're getting this on camera!" at the cyclist while yelling her (faulty) convictions about the rules of the road.



I've thought about getting one myself. Today, watching the driver of a pickup truck towing a trailer have a complete meltdown because the person in the lane in front of him had stopped, third in line, at a red light, thereby blocking his access to the right turn he clearly desperately needed to make now now now - well, watching that, I thought again about pricing out GoPros. Sure, I want it so I can defend myself. Like the Russian drivers, we cyclists need to be proactive, we need to keep tabs, we (apparently) need to "sousveil."

But I'd also love to be able to share some of the gorgeous rides I've been on (and I admit I would also have fun taking it out rock climbing). I once biked with one hand and filmed a large chunk of my ride home along the Riverside Path with my iPhone, with the intention of someday making it into a video so my parents could see my awesome commute. (Still haven't done that; still might. I have the background tune all picked out.)

It begins. . .

This afternoon was the first actual snow of the season, and as first actual snows go, it was a good one: leaving a fine white layer on the grass and rooftops and leaves, and soaking down the streets. And, naturally, I was downtown at my office when it began, so I got to ride home in it. As I type, I'm thanking Quetzalcoatl for creating hot chocolate - one of the really nice things about the snowy season.

So, here comes the winter. We knew it was coming. I know that by spring I'll be desperate for a chance to ride without my shoulders hunched, my brain on overdrive working on balance and watching for ice. But for now, I don't mind that much that it started snowing today. Here goes: that time of the year when I get to feel really badass because I didn't put away the bike.

I don't mind the cold. You can dress for that. I don't really mind the wet, you can dress for that too, although I wasn't dressed for it today and the inside of the left leg of my jeans got soaked up to about six inches above my knee (the other leg was rolled up to keep it away from the chain).

What gets me is the dirt. The incredible amount of spontaneously emerging fine black grit that appears the moment it's "winter," clings to everything you wear, and finely powders the floor of wherever you keep your bike.

That, and when it's actually, actively, snowing it's much more difficult to see, because you're blinking at a rate of about three times a second.

Oh, yeah, and on the first snow? I really mind not knowing whether the drivers around me were good little Canadians and got their winter tires put on before November kicked in.

A little learning is a dangerous thing

On my street, there's a left turn lane where it intersects with a main, four-lane artery. My street itself is quiet and small. I don't think twice about the left turn: I just slide on over and wait at the light or head on through if it's green.

I was doing that this afternoon. Signalled, merged left, pulled up at the red light in the middle of the lane. Then a silver minivan pulled up beside me, on my right - halfway in the left turn lane, halfway in the right, but angled enough that it looked like he was planning to turn left. "Whoa, whoa, what the fuck, buddy?!?" I shouted, startled.

For once, the driver heard me, and responded. He rolled his window down and said something, I don't remember exactly what, asking why I was upset.

"What are you doing? Are you trying to turn left?" I asked him. (His turning signal was not on.)

"Yeah," he said.

I sensed a "teachable moment" and went for it. "So am I. So you're supposed to pull in behind me and wait there."

"No, I'm not," he said.

"Yeah, you are. You're supposed to wait, and make your turn after me."

"Not according to the Highway Traffic Act," he said.

"Ohhoho, yes according to the Highway Traffic Act," I answered.

(What I didn't say was, "Have you read the HTA? Because I have..." Let's have a look at the Ministry of Transportation's Driver's Handbook page on this rule, shall we?)

He cut me off. "No, I can pull up here because I left you a safe distance," he indicated the three feet of space between his door and my handlebars.

"That's not the point, you can't just..." I said.

"I'm sorry if I scared you, but I did leave a safe distance," he cut me off. He sounded so maddeningly certain.

Then the light turned green, and in a Pavlovian reaction I just started into my turn, out of some kind of dread of being in the intersection having an argument while the light was green. And lo and behold, the minivan driver started into his turn at the same time. I threw my right hand out and shouted, "See, that is NOT SAFE!" and as I dodged the cars coming out of the other side of the intersection and made it safely, and with some relief, to the right-hand side of the street, I really hoped that he'd been smart enough to figure out what was wrong with his logic. Maybe he'd figured out that if I'm moving to the outside of the street, and he's moving to the inside of the street, our paths kind of inevitably cross. Making him, sitting on my right side, nowhere near a safe position for me.

Or maybe he just thought I was a panicky woman on a bike and dismissed the whole thing.

I wish I'd had time, or the self-possession, to stop in the intersection and explain the physics to him. How if he's beside me as we both turn left, he's going to have to either cut me off (dangerous) or complete his turn behind me (which he should have been doing anyway). But I didn't. I hope he came to the realization when he was forced to brake and let me continue my turn in order not to sideswipe me. I appreciate that he actually spoke to me, in fact - it's a rare driver that does.

But I'm also a little disturbed by his quoting the "rules" so wrongly. It's like the recent campaign to get people to adopt the three-foot rule has drowned out all else. Worrying: maybe the city should be spending that public service announcement money on more general bike-literacy for drivers, rather than on one rule to the exclusion of others. Because the only rule this guy knew was that he needed to be three feet from me. Knowing that, he figured he was A-OK to do what he did.

A little learning is a dangerous thing;
Drink deep, or taste not the Pierian spring:
There shallow draughts intoxicate the brain,
And drinking largely sobers us again.
