(Disclaimer: Don't read this if you are my mom. There is swearing.)

Yesterday evening (earlier tonight, by my perspective), I rode my bike eleven miles. Not a big deal to anyone who rides with any kind of regularity, except that a year ago I was struggling to ride a few blocks. Exactly six months ago, I was sedated with a breathing tube in my throat.

A couple of years ago, my wife bought me a twenty-one speed hybrid (for non-bike-riding folks, that means it splits the difference between a road and mountain bike) for my birthday. The important thing here isn't so much that she got it for me as that she convinced me that I wanted it. Fifteen years earlier, my bike was not just my primary mode of transportation, it was preferred. But not recently. She figured I'd be happier if I went back to that, and she was right, but getting there was a much more circuitous route that we'd imagined.

I knew I was out of shape, so as expected it was a bit rough getting back into it. I started off by riding a couple of miles a day, figuring I'd set arbitrary benchmarks to gradually increase my range. I felt worn out, but good. After a while of doing this, my breathing felt strained sooner, rather than later in my ride. Exceedingly strained, making me nauseous. It got to the point where I could only go a couple of blocks before feeling so miserable I had to turn around and head home. Then I started feeling it if I did something like go down the corridor to get the mail. There was a hopelessness to it all, that I'd never be able to ride normally again.

In retrospect, I know that it was not my breathing that was strained, but my heart saying, "Fuuuck! We've already had a heart attack, what the fuck is wrong with you? Stop this shit right now! You trying to kill us?"

Mentioning that feeling of strained breathing to my doctor was one of the things that sent me to the hospital for bypass surgery. As he said later, I was doing my own stress testing.

So I feel better now than I did a year ago, before I had a clue how lousy I was. Six months ago, though, was a different story. In the days following surgery, it wasn't the pain (which was often immense) that was getting to me. A lot of little things that made me question if any of this was worth the trouble. Laying in the hospital bed, attached to tubes and wires for days, I was ready to have them put the blockages back if I could JUST TAKE A REGULAR FUCKING SHOWER RIGHT NOW.

For the next couple of months, there was very little I could do for myself. Being told not to lift anything heavier than a bottle of milk is more limiting than you likely realize. My wife was having to do everything for me; I never knew how much I'd want to do my own laundry. I couldn't even focus long enough to watch a movie and justify all this free time.

I was pretty sure that none of this was worth it.

When I finally started going to physical therapy, I was feeling incrementally better, but still not enough to balance out the misery I was going through. In December, my therapist let me know that my doctor had said it was okay for me to start riding my bike again (within limitations); I was pretty happy.

Later that day I rode for maybe a mile before turning around and heading home. I felt good. No strain in my chest. The hopelessness had given way to an honest euphoria, complete with a big stupid smile. I finally felt like all the hassle was worth it, that I'd be able to go further - just not that day.

So eleven miles feels pretty good.

After several days of having my heart rate monitor mysteriously shut off while out riding my bike, it occurred to me when I got home yesterday that it was happening in the same general area each time - somewhere in South Park.

The monitor is narrow band I wear around my chest, with the display on my wristwatch, connected to each other wirelessly. I have the watch set to beep if I exceed a rate recommended by my doctors; it also will beep to let me know it is shutting off, which it does automatically if it's not getting a signal because I've taken off the monitor.

This lack-of-signal-thing made me think that there is some kind of interference blocking the radio signal from my monitor to the wristwatch - a cell phone suppressor, or secret military technology, probably, hidden among the cafes and taverns.

So today when I went for my ride, it was with the intent of tracking down where this is happening. The ride became a walk as I went back and forth, doing laps around blocks, hoping I'd be able to triangulate the source of the interference. I started recognizing people as I went looping around. I can't imagine what they might have been thinking as I wandered around, walking a bike while staring intently at my watch, but clearly not in a hurry.

This map shows a bit of what I found. (You can view the Heart rate monitor interference map a bit larger.)

While crossing Switzer Canyon between the northernmost marker and the middle one I had no signal, but only while on the west side of the road. When traveling on the east side, there was no problem.

The marker to the south had just a small area, maybe a few yards, where I couldn't get a readout. I'm pretty sure there's a larger patch a couple blocks south of that, but I'll figure that out later.

No mysteries solved today, but now I'm thinking about finding my way into Switzer Canyon.
