I've recently tried few applications related with outdoor sports, many are just small apps from young developers, too simple, some are known just because of publicity and image (
censored! 
), then I found
EasyTrails GPS...
here are few notes that I took, just changing a bit another review
It's really the perfect application for outdoor athletes and everybody willing to track their activities. Whenever you are trekking, running, skiing, sailing, traveling or just wandering around, it's just useful and fun!
EasyTrails GPS can tell you how far, how fast and how long you ran... and much more! It also displays the elevation profile and your track on the map in a street/satellite/hybrid fashion. The results can be stored, so it is very easy to retrieve them at any time.
Also, tracks can be exported to a computer to be used with GPS software or shared with others. The app exports your tracks in standard formats (GPX, KML/KMZ and CSV) and can be used with a variety of GPS software including Google Maps, Google Earth, SportTracks (Windows), TrailRunner (Mac) or online services such as Garmin Connect or everyTrail.com.
Version 2.0 can also import tracks through an advanced and easy-to-use "sharing service", which is the flagship of this new version. Import and export tracks has never been easier!
EasyTrails GPS is reliable and accurate. The user interface is very straightforward and navigation is made easier with essential menu items. Besides, the chance to record even while the iPhone is on standby ensures the maximum battery life.
