We cooked up a fun little project along with the good folks at Epic Rides, promoters of the biggest 24 hour race in the country — the 24 Hours in the Old Pueblo.

The Old Pueblo is Tucson, our home base, and TopoFusion author Scott Morris was out at the race last year, collecting GPS data and having a blast riding bikes in the desert.

We took all the lap times from the race, cloned copies of Scott’s GPX files, and sent the dots out onto the course. What results is the closest approximation to what actually happened in the race that you can come up with.

Click through to our 24 Hours in the Old Pueblo Mega Replay page for more info and several videos, including a category winners and solo men, among other categories.

new 2011 splash screen

TopoFusion Pro has a new release, version 4.1, out the first of February, 2011. This version has a long list of changes (see revision history below). Many were requested changes to the user interface, or small added features. A lot of times our users know better what the software should do than we do — we love getting feedback!

A few examples include – higher detail myTopo maps, functions to strip time stamps from files, correct elevation, expire Open Street Maps tiles, add recent files from a GPS’s archive when downloading, and significant improvements in usability and efficiency in TopoFusion’s unique GPS network function.

Head over to the Download Page to try TopoFusion out, free of charge.
