My first couple of days I rode a mile or two around my neighborhood. About 3 days in, I went to a bike path with a goal of 4 miles. I had so much fun with no traffic or stop signs! When I stopped and checked a mileage sign (and turn around) I had already gone 4 miles. I soon realized that these first 4 miles were downhillish and with the wind. The ride back to the car was the longest 4 miles of my life! Within 2 months my husband and I were up to riding 12 (me) and 17(him) miles on this same path 3 times per week, but we now park at the other end. Here in Texas, you have to really work on building tolerance to the heat as much as to the activity. I started keeping a calendar of my miles and setting secret goals for myself...20 miles per week for 3 weeks in a row, 50 miles per week, etc. My mother in law moved in with us last Spring and that completely stopped our riding. We just hired a sitter for Sunday mornings and Tuesday evenings so we can get out some. First ride in over a year this Sunday was 8 miles, 100 degrees and kicked my butt!
There's a walking/running app where you pretend zombies are chasing you. Has anyone seen one like this for biking?
