I did almost a mile and a half. It's been a while since I walked there, I forgot how the path inclines, and declines, zig zags, curves and tilts. I must say it was very relaxing. I had my new headphones and old MP3 player handy to keep a consistent pace.
Fun fact about my MP3 player, I got it in 2006, it played a strong role in the weightloss I experienced that year from walking at the same park and to and from school. It uses one triple A battery, has a usb connector and a SD card slot. In the years since I've had this I've gone through 5 different generations of iPod and yet this remains. It's not glamorous, but it works just as well now as it did then
