How do you know your speed?

You ladies are all wonderful! Thanks so much for all that info.

I'm definitely going to get a computer when I get my bike. It reminds me of buying a heart rate monitor for going to the gym ... not necessary, but helpful and fun and motivating!

Now I want to plug in some routes to that online map to figure out how long to go next weekend on the rental bike.

I use an app on my iphone called GPS lite. I'm not sure how accurate it is, but that's what I use because it gives me my mileage and speeds for set intervals.
