Many years ago, I used to make it a point to ride my bicycle to work at least twice a week. As long as the weather was reasonable.
I had panniers on the back of my bike that I kept my layers and work clothes in. There were bike trails that I could follow most of the way and I'd spend minimal time on the streets.
It was quite pleasant, I'd start out right before dawn. The sun'd come up, morning mist'd burn away, birds'd start singing and it'd start getting warmer. If there was anyone else on the trails I'd greet them with a smile.
There was a bench within 5 miles of my destination and I'd stop for a power bar breakfast.
By the time I got to work, I was all mellowed out. Stress was a lot easier to handle when ya start out mellow instead of stressed out by traffic.
On my way home it'd get dark and I'd switch on my bike mounted headlight. The stress of the day'd roll away with the miles.
Not counting side trips, my ride was 24 miles one way.
When my car was in the shop. I'd just take my bike everywhere. Grocery shopping, I'd just wear a backpack.
I used to be in pretty good shape.
My bike ain't no lightweight either.
