Well, I have been cycling (road cycling) almost everyday for about 3 years now. I usualy do between 70 and 90miles a week when the weather and my job enables it. When I resumed cycling back 3 years ago after 15 years of pretty inactive life I was exhausted after only 3 miles. I started cycling again cause my PCP found that I had high blood pressure and high cholesterol and advised me to exercice. Since I do not like jogging I bought a cheap mountain bike and started cycling. I got into it and after 8 months riding my crappy WalMart mountain bike I bought a serious road bike and have been cycling since almost everyday. With my bike I have discovered how lovely my county and my state are.
