People have been asking me about my ipod thingy (I don't know what to call it!) so I thought I would explain & show pictures. If I just explain it it can be a little confusing. So here it is!
This is the sensor & plug in for your ipod. I got mine for $30 at the Nike Outlet at the Legends. You can also order them online.
You can spend a bunch of money on the special Nike shoes that the sensor goes in the bottom but I didn't. You can buy a pouch that laces onto your shoe for like $7 online.
You don't even know the pouch & sensor are on your shoe while you run!
You plug the other thing into your ipod & when you turn it on you see "Nike + Ipod". That's where you go! You can have it programmed by time, distance, calories burned, etc. I have it programmed by custom distance so I can change it each week when I run farther. It comes on & tells me when I've run 1/2 mile, halfway through, 1 mile, 300 meters, etc. Then it tells you when you have run your distance. Lance Armstrong comes on & tells me when I've run my fastest mile & some chick comes on to tell me when I've run my farthest.
It is really cool & I highly recommend getting one if you need some extra motivation or encouragement to walk or run!
