1: You can use the squeeze button on your iPhone headphones to control the application. Particularly useful if you don’t feel safe putting your £500+ phone in a pocket while cycling (assuming that you take a backpack with you). I have a set of bluetooth headphones that allow me to easily listen to my music, start/stop Cyclemeter and request updates on my rides (or hear them at time intervals/distance intervals) without the bother of wires.

2: If you’re having issues with gps fidelity, try turning off wireless or taking the phone out of its case (if you use one).

3: Unfortunately, my iPhone3G has a crap battery. If I want to do a long ride I have to be sure my phone is charged before I go and sometimes I use an Mp3 player instead of using the phone’s built in iPod. I’m sure you have fewer battery problems with the iPhone4, but it may be worth getting a battery accessory.

4: Make the most out of the Twitter and Facebook integration. You can customise when the app Tweets or posts to Facebook and how much information you show, including a map link so people can follow your route. It can even read out Tweets and Facebook comments to you.

The most useful thing for me by far is the ability to start/stop the app recording from pressing a button on my headphones (it’s a slow double-click, as a normal double-click skips to the next track in the iPod). It makes using it really hassle free.
