About 4~5 years ago, my folks gave me a little Garmin eTrex GPS unit. It's pretty basic -- can't load maps, etc. -- so I really didn't use it much.
Recently, I've been working on mapping out some new routes so I broke it back out and began playing with it. At first, I didn't think there was much I could do with it -- Garmin doesn't offer much in the way of software to work with it.
After digging around online, I found a couple GPS utilities that would allow me to pull a GPX file from the eTrex that I can upload to Bikely, etc.
I set it up this morning to record my commute then used a nifty little app called LoadMyTracks (Mac) to pull a GPX file off of it when I got to work. A quick upload to Bikely and there you have it -- a nicely mapped out route: The elevation profile info seems really off -- there were times on the ride where the speed seemed to be really off -- possibly because of dense tree cover in Umstead park, etc.
Overall, it looks like it'll be pretty handy tool for mapping out routes. Ain't technology grand?!
