Yeah, you go girl! last summer I rode about 1000 miles. About 10 years ago, I too was really out of shape and could ride only about a couple miles without huffing and puffing. Even tho I ski all winter, that isn't much work or very aerobic. I also developed high blood pressure. Now the bp is down, I lost 30 pounds last summer and feel SO much better both physically and emotionally. I ride alone mostly (can't get fat DH to do much) but I love it and have actually acquired 3 bikes (road, mt, cyclocross) and use them all. (I am 63 by the way). My son is proud of me and gives great encouragement. Family may make remarks at the beginning but they WILL be proud later!
