Rob Boyer writes to tout his new software application, Ascent: “Ascent is a new application written for the Macintosh that is designed to help cyclists, runners, and hikers train better by displaying, in various ways, their activities uploaded from GPS devices. An activity’s path can be shown on various maps, and animation features allow the activity to be re-played with a heads-up display showing instantaneous data values such as speed, gradient, altitude, and heart rate. Ascent imports/exports GPS eXchange files (.gpx), and can directly upload data from Garmin USB GPS device.” $35 shareware, feature limited until registration.
