Sportypal.com has released an application called Sportypal that will run on almost any type of phone that has GPS built-in. It works on iPhone, Android, Windows Mobile and phones that support Java. 
A anspshot from my workout. To put it simple, it uses the GPS in your phone to track speed and distance mainly, but also will track elevation during an activity then allows you to upload it to the SportyPal website. If you are familiar with the Garmin line of watches, think of that functionality. The application starts, acquires satellites connectivity, then you hit the Start button when you are ready to get moving. The application, while running, looks like a stop-watch with some additional real time information like speed/pace, distance covered, max speed and climb. You also have the ability to change to a map view that will use Google Earth to display your location on a map in real time. After your workout is over, simply hit Stop. Your info will be stored on the phone and you can just go write down your data in your log book.
Using the data connection on your phone, you can post the workout immediately to the SportyPal webiste. You actually get prompted for this after you choose to finish the workout. Once the workout is posted you can head over to your computer and see the route you just covered as well as more detailed data. You will see icons on the map for things like; Start, Stop, Fastest Speed, Highest Elevation and a few other things. Of course like all websites these days, there is the ability to share your workouts with others as well as have friends who are also using the site and share their training with you. I'm using it on Android and here are some shots: 
Also there is the opportunity to embed the maps, and include whatever the original Maps page displayed -- including business and address search results, driving directions...
Great stuff if you want to show people the place you're writing about in a blog post, or if you're organising an event and want to show people where it is.
