3 miles each way. 105ft uphill and 180ft downhill going to work and 200ft uphill and 121ft downhill coming home. (according to Google)
I bike more leisurely going IN to work and bike a little harder going home. When I moved here I purposefully chose a location within a 10-mile radius of work with the expectation of biking 5 days/week or more. Keep in mind, I was exercising maybe 1 or 2 days a week at a light pace, so this was a huge change. I've noticed a sweat less now (2 months in) going in to work. (we don't have showers, so I bought a fan for the office and go in earlier to mitigate the sweat/heat)
My coworkers reactions are amazing when they realize I bike to and from work every day. Most of them never noticed I biked unless they saw me coming in or leaving all "geared-up" with helmet, bike, panniers, etc. I'm tracking a 6-month period of "transportation expenses" to see what my total cost is per month. I imagine it's cheaper than a car, even with Zipcar rentals, Hertz rentals and Lyft/Uber when I need it. (mostly weekends to far away places or things that are too big for my bike)
