All of the items described in the post, with a bonus photo of the dog, Bebe.
Here is what I carry on my morning run commute. I am a minimalist. That philosophy requires discipline. Every now and then, I wish I had brought along this or that, but that is rare enough – I’m fine with the risk.
I use an ultra-lightweight backpack. It is a cheap but durable nylon number by Marmot. It isn’t specialized for this purpose. If I cinch the shoulder straps, it is stable enough. The interior contains a divider between two compartments, which allows me to stow sweaty clothes after changing. There is a little zippered top area, too. I liked it enough I bought a spare when it was on sale, so if I need to throw one in the wash or take one on a trip, it’s fine — I travel enough that I sometimes leave the extra at my elderly father’s house, so it is there when I check on him. The only problem with this model is it lacks any padding. I cannot throw it around for fear of damaging the gadgets inside. That only means I need to be careful. Or I could buy a separate case for the tablet. (For races, I switch to an Ultimate Direction vest.)
Inside the backpack, I have keys (two: house and office) with a high-powered flashlight attached, on a tiny locking carabiner. I have a driver’s license, work ID, credit card, and MUNI pass for the trip back, in a card case style “wallet;” an iPhone; and an iPad with my files for work. It is that last item that has made the run commute feasible. Basically all my data is accessible.
Oh, I also have a camera with me. I almost always have that, a real camera, typically a vintage film camera. That is extravagant. It weighs as much as everything else put together. I took up running and photography simultaneously, and for me they are associated activities. Others likely would forego the film camera.
Finally, I have a partial change of clothes: fresh socks, t-shirt, and shirt. I also have a lightweight towel meant for athletic use, about a quarter the size of a bath towel and much thinner. I sometimes carry another pair of pants or an extra pair of shoes, especially if there is inclement weather. I’d prefer not to do that though. I wear pants that are acceptable, as I judge it anyway, for a casual work environment. (My wife has a “no-fly” rule: if I am out with her, my pants must have a fly; these do.) I also have a cap, because my mother taught me to err on the side of putting something on my head when it was cold. (The running cap is soaked through with sweat when I arrive, so that has to be swapped out.)
There are omissions. I sometimes wear headphones, but I’m ambivalent doing so. If I will be going back and forth — a great day includes a round-trip run commute — I might pack a spare battery.
All of the above are shown on a list. I am an inveterate maker of lists. That is a bit OCD. But I wouldn’t be comfortable if I didn’t check off these items before I started out.
Run commuting compels me to plan. I have to consider what else I am doing that day, to ensure I bring what I need. If I am headed to the bank, for example, I add my ATM card in a separate “wallet.” But I do not want to be burdened by baggage. Most of the stuff I own, I don’t use. I no longer feel any need to acquire material goods in general, unless I am confident it will become integral to my life. I’d rather be out there running. There is always someplace else worth the journey.
