I noticed how many people mention "because I can't bike on the highway". Probably the most important lesson if you're thinking of trying to ride a bike for errands, bike to work, fitness or just because is .... don't ride the route you'd drive.
Think side streets, parallel, off streets.
Between lights (and yes, I stop for stop lights on my bike but in a car sometimes miss two lights because of traffic) and finding parking etc it's faster to ride than drive to work. But even with cycling route specific maps it took me almost a year to find a great safe route.
It's not only safer but more pleasant and scenic.
Many people would like to bike or walk to errands or work but don't feel safe. If there are no specific bike routes or few in your area check with a local bike club or shop, they often have maps and suggestions for the safest routes.
If you're nervous about the time or logistics try it on a weekend. Get up, have coffee, read the paper, laze around and then set your watch and grab your bike. Head to work or do an errand. If you don't get there in time or are tired ... it's ok, you're not late.
Don't forget to have fun, stop for coffee and breakfast. Make it a fun trip. It took me a few times before I found the right route. But I did find there's actually some great coffee shops near me that I did not know about ;-)
As for the sweat: I bring a small kit with me, baby wipes, deodarant and a change of clothes. Also slow down the last half mile or so before work (you don't really want to get there anyway, right?) allows you to stop sweating.
Over 40% of US trips are within 4 miles. If as many of us that could did some of these errands by bike, walk, coordinating trips or linking errands can you imagine what this would do for the demand/price of oil?
Hee hee, take that Mr. Big Oil we need 40% less.
Google Cliff Bar Challenge and you'd be surprised how much you can do within 4 miles or less.
And if you can't bike or walk due to situation or disability we understand, just please don't hit me ;-) Be considerate of cyclists. If we all obey the rules of the road we'll get through this. Remember I'm dropping the demand/price for oil FOR you. And yes, I have a car also.
