For 10 years I used my lunch hour. We had one shower and sometimes it wasn't possible that I could shower. In my travel kit at work I always kept a can of Evian atomizer (feels great on hot, sweaty face), astringent for odor, deodorant and a mini cosmetic set and a towel. Hair sometimes had to be redone into a ponytail and keeping a professional appearance was important.
I now work 4-10's with 30 min lunch and remember fondly those days of 3-5 mile runs. That was my time. Only had 60 mins, nothing more and would discreetly eat at desk.
This was the perfect time for working mom's. My husband worked nights and it just wasn't the same dragging two kid's along for night runs. I needed my own personal time and that fit the bill.
