I have one (RCA Lyra) but would never take it on a run (I enjoy the quiet so I can fully take in the lovely odours of Detroit-Windsor). I do use it for my walking though.
I bought an MP3 lately and find certain jazzy tunes pep me up. I think everybody would like to afford an iPod Nano but I have looked at several and settled for a Sony NW-E403. The price is mid range and because it does not have extras that I don't need such as FM radio, or additional storage the quality is quite good. Beware of low cost MP3s with many extra features as the quality is not there.
Ok now that I can see, the majority of u either own an ipod mini or want 1. What is different about my MP3 player, and an ipod mini? Is it that the iPod mini has more memory? Why do people pay $200 for an iPod mini? What special features attract people to buy it over a regular MP3 player?
I have an MP3 player, but I never use it running... you can't race with them, so why get use to it?
I have an iPod nano 8 gb - $100 on eBay (refurbished). I like having the nano and the music, but two things have really helped me:
1. The Nike + system (http://www.apple.com/ipod/nike/)
It tracks your overall miles and pace, but even better is the challenges.
Challenges vary from:
"Let's run X miles in X days" - everyone tries to run X miles in X days - not a person vs person thing, more of a everyone vs miles thing... a lot of "let's all do this" type encouragement
"First to run X miles" more of a person vs person thing = more trash talk.
"Fastest X miles" = too competitive for me, I'm not into speed...
2. I do the run-X-minutes-walk-X-minutes Galloway thing, so I took an hours worth of my favorite mp3s, joined them all together (http://www.shuangsoft.com/Shuangs_Audio_Joiner.asp) into one large mp3, then split them into even length mp3s (mine are 1 minute each) using the mp3 splitter: http://www.codevisions.de/
I then took each minute segment and joined a "beep" mp3 on the end, then I joined them all back together into one long song (it's a lot easier to do this than it sounds).
So now I have a running compilation that beeps at me every minute to tell me when to walk, when to run.... the Nike + tracks my pace, time and miles - no need for a watch.
