I'll take a few minutes to map out some screens for the proposed iPod application today. Also have a lot of data on 1k pace and guessed at 5k so I should start a little graph on the side-bar. And a side-bar item for links that my friends and mentors have given me that I have used.
I read some guy did sprint bursts during his 5k, but lost the link to the story. I think changing up the running pace would be good for me - tried to change it a little on the last piece of the run and "felt" more refreshed.
Keep your chin up folks - if an old man like me can think he can be a runner then you can think you can be anything. The rest is just execution!
