the apple watch series 10, my first 5k, and eighteen honest hours

I signed up for a 5k in october 2024 because the group chat did, and I have never once in my life said no to peer pressure. Then I ordered the apple watch the same week, which is called connecting purchases to a personality, and my wallet and I have discussed it since.

the honest bit, shoes included

I paid $399 for the 42mm series 10 in rose gold aluminum, at launch, plus a third party woven band for $12.99 in a beige so specific it matches the bakery boxes from the good bakery. The watch was not the expensive part. The expensive part was running shoes, a foam roller I use as a footrest, and the dawning knowledge that I could not run for ninety consecutive seconds.

Plainly, the series 10 is two generations old now. Apple replaced it with the series 11 in 2025 and the series 12 this september, and mine is still here being thin and rose gold. I can only tell you what it cost me, not what you should do, because I am a blogger and not an accountant.

what i actually care about, in order of care

It is thin enough that sleeve cuffs forgive it. 10 percent thinner than the one before, with the widest screen apple has put on a watch, and the extra line of text is a real thing: I read whole messages on my wrist at red lights like a functional adult. The screen also stays readable at an angle, which matters more than it sounds when your wrist is in your coat pocket.

Charging is the quiet superpower. 80 percent in 30 minutes, so the routine became: watch comes off, watches me shower, goes back on. I have never once started the day under 90 percent. My old fitbit died at 4pm like a houseplant I forgot to water, and I keep a plant alive even less often than that.

The 18 hour battery is the complaint you will hear, and it is fair. You charge it every night. That is the deal. Some people see that as a failure of imagination by apple and some people see it as a bedtime ritual, and I have done both in the same week. If you travel, pack the puck. That is not advice, that is what I did wrong once in a hotel in indianapolis.

Sleep tracking turned out to be the main event. I wore it to bed for the sleep apnea feature, which watches your breathing over a month before it says anything. It said nothing, and I sat with my coffee feeling something about that. The sleep graph also taught me that I sleep terribly when I blog at 1am, which I already knew, and now have data about.

Blood oxygen came back and it was a whole saga. The feature was switched off on new watches in the US for a long stretch over a patent fight, and apple quietly brought it back in august 2025 with the math moved to the phone. One day a year into owning mine, the sensor just started existing. I thought about how strange it is that a feature can be missing and then arrive, like a shelf you finally install.

The workout tracking is where I stopped being cool about it. It counted the walks with the dogs, it counted the training runs, and it put a ring on my wrist that I close like it is my job. The tides app and the water temperature sensor are features for people with boats, and I do not have a boat, and I looked up lake michigan's water temperature anyway.

the tangent with the hydrangeas

Race morning, the watch loaded the course before I did. Mile two runs past houses with absurd hydrangeas, blue ones, the color of a bowl of frosting, and I remember looking at them because looking at them was easier than breathing. Dana was at the finish holding two coffees. My pace was a 14 minute mile the whole way and I want that in writing: fourteen. The watch said 3.12 miles and 41 minutes and a heart rate graph shaped like a mountain range, and I screenshot it and sent it to the group chat and then sat on a curb.

That graph is the only fitness data I have ever cared about. The watch was there for all of it, and now it is a diary with a strap.

the soft landing

I keep thinking about whether the ultra would fix my one gripe, the nightly charge, but its case is huge and my wrist is

The truest thing: this watch noticed my heartbeat at mile two and stayed polite about it. It came to the 5k with me. That is what it cost and that is what it did.
