I love running, i used to do it on a regular basis when i lived in lisbon, around 45m three times a week, just pick up my ipod and run till my heart started to call for help lol
At this moment i don't find much free time or good places to run so i do most of my cardio home with a bycicle or just a few squats. But that feeling of running on the street, wind blowing in your face, some bon jovi music pumping trough your ears, woot, love it.
