Good to go.

Few years ago when I first started running I obsessed about miles and times. One day I just kinda realized that the watch I was wearing was stressing me more than any fun or benefit I was getting out of it.

I took the watch off and now I run for fun and health and it's a glorious thing. I don't concern myself with times or distances but I just get out and run. I have a rough idea of how long I've run and from that I can figure out how far I've run easy enough.

I'm with you. Do your thing and don't worry about how many miles you lay down.

Disclaimer: While the above statements are true for running I have two computers on my primary bike. A regular bike computer and a Garmin 705. I'm having a blast with the GPS.
