Hy,

I'm the author of bbTracker, so take whatever I say with a grain of salt

bbTracker should be good for your use case, as the reason I wrote is was that I wanted a tool for a similar use case (I'm inline skating). Viewing on Google Earth works just fine.

Unfortunately development is a bit stalled currently, but the current version 0.4.1 should be quite usable already.

If you find any feature that you were expecting or that you wish was there is missing then please don't hessitate to report that as an issue or look if that request has already been filed.
