I highly recommend the free Loxtrax program available at
Magnalox. (I am not affiliated in any way with the site other than as a user.)
It creates GPS logfiles that I record/store on my Axim and is a great way to chart courses, check speeds, elevations, etc. It then can be used with Google Earth or other mapping programs... You can also add in pictures later to turn it into a travelogue.
Here is from the website:
Magnalox visualizes GPS logfiles as annotated, interactive tracks displayed on maps or in three dimensions using Google Earth. It can be understood as a new kind of travelogues, which can enriched with texts, photos and links.
