Golden Cheetah
PowerTap Software for Linux and Mac OS X

Download
Right now Golden Cheetah is available as source code and in binary form for Mac OS X on PowerPC processors and Linux on x86 processors. Depending on your operating system, you may need to install the FTDI virtual COM port driver if you're using the PowerTap's new USB download cradle.

Source Code

The Golden Cheetah source code is available via Subversion. You need to install QT 4 and qwt 5.0.1 (as a static, not dynamic, library) and edit goldencheetah/src/gui/gui.pro to point to them before building GoldenCheetah. Use this command to check out the current version of the repository:

  svn checkout http://goldencheetah.org/svn/trunk goldencheetah
You can also browse the source here.

Binaries

Date Files Description
Mar 10, 2008 Linux x86,
Mac OS X Universal
This release introduces BikeScore™, a metric of training stress developed by Dr. Philip Skiba. It also fixes several small bugs in earlier releases.
Sep 23, 2007 Linux x86,
Mac OS X x86,
Mac OS X PowerPC
Bug fix release. CVS imports weren't quite working in the last one.
Sep 18, 2007 Linux x86,
Mac OS X PowerPC
This release adds two small, but excellent features from Justin Knotzke: CSV file imports and visual interval markers in the ride plot.
Aug 7, 2007 Linux x86,
Mac OS X PowerPC
This release fixes a bug in the critical power intervals graph where you could get bad data if you started an interval after a long period of not moving. It also adds really basic zooming to the ride plot: use the left mouse button to zoom in and the right one to return to the previous zoom state. It's pretty crappy right now, but it's better than nothing.
Apr 26, 2007 Linux x86,
Mac OS X PowerPC
This release fixes some bugs and adds a whole bunch of new features:
  • Now imports .srm files (direct download from SRM hopefully coming soon)
  • New "Weekly Summary" tab shows total weekly hours, miles, and work
  • Power zones can now be entered into a text file, after which GC will display time in each zone in the ride and weekly summaries; for more information on the zone file format, see this page.
Apr 1, 2007 Linux x86,
Mac OS X PowerPC
This release fixes a bug that was introduced with the hardware echo detection code. If you're using the CycleOps-supplied USB cable to download from your PowerTap unit, this release should make downloads more reliable. (Those using the KeySpan USB-to-serial adaptor or a plain-old serial port shouldn't see any difference.)
Feb 22, 2007 Linux x86,
Mac OS X PowerPC
Clicking on the Critical Power Plot now displays the interval duration, maximum power for that ride, and maximum power for all rides below the plot. Also fixes a bug for recording intervals longer than two seconds.
Feb 12, 2007 Linux x86,
Mac OS X PowerPC
Interval information now included in ride summary, rides can now be exported as comma-separated values for import into Excel, and better automatic detection of hardware echo. Also includes a number of bux fixes.
Jan 30, 2007 Linux x86,
Mac OS X PowerPC
Bug fix release.
Jan 6, 2007 Linux x86 First release for Linux.
Dec 25, 2006 Mac OS X PowerPC Adds the Power Histogram, which shows how much time a rider spent at each particular power level during a ride.
Sep 19, 2006 Mac OS X PowerPC Adds the Critical Power Plot, which shows the highest average power you've achieved for every interval length over all your rides and the selected ride. Also shows download progress in minutes of ride data downloaded.
Sep 7, 2006 Mac OS X PowerPC Adds speed and cadence to the ride plot. Fixes a bug found by George Gilliland where reseting the time during a ride could cause the GUI to crash.
Sep 6, 2006 Mac OS X PowerPC The first release of the Golden Cheetah GUI.


Older Stuff

These are the older, source-only, command-line distributions. I've left them up for historical purposes only; I don't recommend using them.

Date File Description
Aug 11, 2006 gc_2006-08-11.tgz ptdl now works with Keyspan USB-to-serial adaptor, after debugging help from Rob Carlsen.
