These 3 files, CALBURN.{TXT,WK1,XLS}, are PC based text, Lotus, and Excel 
format files.  They contain data extrapolated from a chart published in the 
May, 1992 issue of Bicycling Magazine (Article: Fitness Q&A, 10 Common Fitness 
Questions Answered, p.50).

The base data as listed in the magazine article is given as the first
portion of the spreadsheet.  I have then interpreted the data in two ways:
with the time spent pedaling as a variable and fixed weight of 210 pounds
(my current weight plus my bike in commuting trim), and secondly as a fixed
time interval of 60 minutes and variable weight of both bike and rider.  Both 
are charted against miles per hour.

Fairly simple stuff, but quite useful.  Enjoy.
