I&#8217;d just woken after my first night on Bainbridge Island, lethargic after a two-day flight from New Zealand but excited: I&#8217;d been waiting years for a chance to run with Greg Nance, a close friend of my cofounder and the closest thing I knew to a celebrity runner. He had a sponsorship, a running-branded license plate on his pickup truck, and even a Strava stalker.</p><p>He&#8217;d invited me out for a run to help me shake off my jet lag. I expected a slow jog, but it turned out to be a <a href="https://leeknowlton.com/blog/bainbridge/">5k race</a>. I wasn&#8217;t ready for this physically or mentally; my mind thought I was a high school senior, but my body knew I was an untrained man in my mid-thirties. And so it was that I finished in about the same time as the first 5k I ever ran, as a high school freshman who tripped twice from exhaustion.</p><p>Yet that race was enough to rekindle the small flame of competitive spirit I needed to jump back into running. When I got back to the Airbnb I was sharing with my two colleagues, I bought a digital copy of Daniels&#8217; Running Formula and started plotting the training I&#8217;d need to beat the runner who&#8217;d finished ahead of me.</p><p>With a Parkrun 5k every weekend, I had plenty of chances to improve my time and finishing place. I kept getting faster while moving through one small injury after another. After getting down to around 20 minutes, I started to place in the top 3 and naturally set my sights on Greg, who had come in first every single week. I told one of my colleagues, Andi, that I was feeling pretty confident I could win if only I trained &#8220;for real,&#8221; to which she dutifully called out my bravado with &#8220;prove it.&#8221;</p><p>And so with a &#8220;prove it&#8221;-shaped chip on my shoulder, I started training more seriously. First, I&#8217;d adopt Greg&#8217;s protocol of running a mile every day; once I settled into that, I&#8217;d add 10x400s around the track or even two-a-days.</p><p>To the surprise of no one with any sense, I injured myself again about a week later. This time it was my calf. But I had already started the mile-a-day streak, and I&#8217;d decided to push through. A painful Fourth of July 5k came and went, and after that, my calf healed and my ankle got hurt. My ankle healed and then my knee got hurt. And yet I stuck with the streak. Hell hath no stubbornness like the bruised ego of a former high school athlete.</p><p>A couple of months later, the streak was unbroken and I was standing in the garage on the first floor of our Airbnb. My other colleague had left and I was helping Andi load the final pieces of her luggage into Greg&#8217;s pickup truck. I hugged Andi and broke into tears trying to say goodbye. I looked away, but seeing my makeshift bedroom down the hall did little to help. Greg came over for a pat on the back and reassurance. I gave Andi a final hug, Greg a final hug, and they were gone.</p><h2>II.</h2><p>I&#8217;d left my wife and one-year-old at home to fundraise and failed with nothing tangible to show for it. I&#8217;d also run out of time to beat Greg in a Parkrun. But I had a streak, and that might not have been tangible, but it was also not <em>nothing</em>.</p><p>In the meantime, Andi had begun a streak of her own and Greg was continuing his. I figured running could be a way to feel connected to them and the Parkruns as I returned home. I&#8217;d go out for a jog and then hop on Strava to see what they and my Parkrun buddies were up to.</p><p>I was happy to be back home with my son, and I kept going out for my runs. I even went to a Parkrun in New Zealand and set an adult PR (though still not faster than Greg).</p><p>A few months later, we moved back to Japan to be closer to family and were staying with my in-laws while my wife interviewed for jobs. One day, when things seemed calm, I slipped out for a run in the middle of the day. When I came back ten minutes later, my wife told me that my son had been crying because I&#8217;d left. My mother-in-law said to take more care when going out, because my run was a burden on the household.</p><p>I was resentful. I&#8217;ve always had a hard time making others uncomfortable, and tend to take hard things onto myself rather than inconvenience anyone. If the roles were reversed and they&#8217;d needed to go out, I would have handled things. If it had been for work, they wouldn&#8217;t have complained. The difference was that I&#8217;d gone out for something they thought was unimportant.</p><p>And yet there was no reason for them to think that my run was important other than me saying so. They really did have to handle my crying eighteen-month-old, upset that his father was not around again. He could wail and shriek in a way so exhausting that anyone would come away frustrated and desperate to prevent a recurrence. But the next day (with as much care as I could take), I went out again.</p><p>None of their frustrations with my running were unreasonable, and yet it felt important to continue. Giving in would have been a greater loss than the short-term discomfort everyone was feeling.</p><p><em>If I skip today, I lose respect for myself, I lose connection and become alone, I lose a thing that&#8217;s just mine and no one else&#8217;s.</em> I could say that the fundraise failing wasn&#8217;t all in my control, but there has not yet been a day I was physically unable to run a mile.</p><p>I ran through food poisoning, several colds, and the flu. Sometimes I took my son with me in his stroller, but every single day I made it out for a run. I often didn&#8217;t want to, but I needed to. For connection, or resistance, or a small win that would make the rest of the day a success, or something. My family remained skeptical but, to their credit, even reminded me to go on the odd occasion. It became a fact of life for us.</p><h2>III.</h2><p>In August 2025, a little over two years after I&#8217;d started my streak, I went running on a hiking trail. The uphill was steeper and slower than I&#8217;d imagined, nearly 20 minutes for 800 meters. I&#8217;d told my wife and son I&#8217;d be back soon, and I was already behind my self-imposed schedule, so I ran the downhill carelessly. The next day was fine, but two days later my knee was sore. I cut back any excess miles and slowed down my training, but the soreness didn&#8217;t go away. A few months later, I went to the doctor, got some scans, and was diagnosed with runner&#8217;s knee. Nothing permanent, but they gave me a wrap for the knee and some patches to reduce inflammation.</p><p>It&#8217;s been 11 months since the injury and it still hasn&#8217;t fully healed. But I still make it out every day, and recently added pullups to get my upper body fitness closer to my lower body.</p><p>Yesterday was Day <em>one thousand one hundred and eleven</em>. I did the same route I do most days, heading out from home and onto an all-weather running path overlooking a ridge that used to serve as a road between Okinawan castles. I&#8217;d place the knee pain somewhere between a 0.5 and a 1 out of 10, enough to keep me from pushing, but not enough to keep me from running.</p><p>Greg&#8217;s streak is still going; I think he&#8217;s at around 2,300 days. Andi stopped hers for a while but has recently started running again. The funny thing about streaks is that you can&#8217;t catch other people. That irks me.</p><p>When I run now, I&#8217;m not holding on to connection or chasing a target time. I do it a bit for resistance, but that&#8217;s mostly gone away too. If I had to put a <em>why</em> on yesterday&#8217;s run, it would be something like &#8220;it got me out for my pullups, which I&#8217;d probably have skipped otherwise.&#8221; Tomorrow I&#8217;ll be running for pullups again, but I don&#8217;t know what my &#8220;why&#8221; will look like a year from now.</p><p>Beneath every why, though, there has been a sense that this is something I can count on, almost like the run itself is a person to whom I&#8217;m connected.</p><p>Today will be Day 1,112. I&#8217;ll lace up, go out, and run a mile, maybe a bit more.</p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://letters.leeknowlton.com/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">Thanks for reading!
