Recently I have found 2 new features on the Nike+ web site that I thought I would mention incase other people have missed them.

The first is that you can now search for challenges (called filter on Nikeplus). To do this go to the challenge gallery and view all changes and then filer by Title.

The second is the Nikeplus trainer, this only appears for selected countries. For countries without this feature you can log into Nike+ and select the American site by clicking on [country selector] next to the flag in the bottom left of your screen and navigating to the [United States]. Then in the main window you can find an option to "Train with Nike+ Coach".

Has anyone else found new features that they have found useful?

Don’t know if it’s new or I’m the last one to know. I did see it in the Nike+ forum:

Thread: Most Wanted Nike+ Features

If you want automatic feedback of the distance you run e.g. Km, 500 m, Mile, half mile. Set distance setting to e.g. 1km and when you passed that then every half km past that it gives auto feed back saying "1.5 km completed, .5 km past your goal," and so on every half km.

I have only tried it once, it supposed to give feed back half the distance you set so if you want the auto feed back every km you have to set the initial distance to 2 km.
