I have worked out at lunch without a shower for years. I'm a guy, and never had a problem. (Meaning my method should work for men, but not sure with women!)

People really, really overthink the need for the shower. Just take a shower in the morning, then do you workout at lunch, and then have a good cooldown period where you can stop sweating after it, and then just use a normal towel to wipe down the rest of the sweat. Go to a normal bathroom and just wash your face, head, and neck. Towel off again, change. If you want to go the extra mile, use deodorant that you like before and/or after. f you don't have immediate access to a bathroom after the run, just cooldown outdoors, change (somehow, ?car), and use the bathroom to wash off later, there is no rush.

Seriously, it's not a problem at all. I work in a 'professional dress' place where a tie would be appropriate and casual clothes are never appropriate, as well.

Forget all those wipes, parking lot showers, and fancy solutions. It's literally AM shower, towel, wash face-neck, change. I

The most helpful thing to have is a location where you can change. Obviously any bathroom will work, but it's more pleasant when you have a lockable office so you're not dealing with putting clothes on questionably clean surfaces.

I even bike commute 1-2x/week (full sweat), still have no problems with this despite commute-lunch run-commute. And my workout for today's luncn will be 5 x 5' as hard as possible (near-VO2max) alternating 3x' off, total 1 hr running, in close to 90F heat when the sun is factored in. It's gonna be a sweatfast.

X2. My understanding (and experience) is that sweat, by itself, doesn't stink - meaning there's really no need for an immediate shower after the lunch workout. It's the bacterial growth that happens over time that produce the rich smells, and that just doesn't happen in the hours between the lunch run and the end of the work day. I typically work in an urban office setting. My practice has been to change in the bathroom handicap stall, put work clothes back in my office, run, walk / cool down post run as much as possible, sit back in the office doing computer work until I seem to be done sweating, then head back to the bathroom to change. I've never ha any complaints or issues raised by wearing my running clothes out of the building or wearing them in my personal work space while I'm cooling off.
