Watt Matters is a blog about training and racing with power and other related musings.

Aside from writing items here on occasions, I also provide cycling performance improvement services via coaching, aerodynamics testing and host a cycling tour.

If you'd like to ask me a question or suggest a topic you'd like my take on, then just head to Ask Alex and let me know!

Aerodynamic Drag Testing Using a Power Meter

Earlier this year, with the assistance of Dr Andy Coggan, I put together a protocol and spreadsheet to assist those with power meters to undertake their own aero drag testing.

The sheet can be found at the trainwithpower.net site here:
CdA-Crr.xls

All instructions are contained within the Excel file. Thanks to Charles Howe for developing the trainwithpower site and hosting the sheet.

The online discussion at the Fixed Gear Fever Forum can also be viewed here:

Enjoy!
