Recycle those race numbers

I have found another great use for the growing pile of race numbers. Not only do I reuse the No 1s, 2s and 3s at Wells Ave.. (having a name beginning with "A" gets low numbers in pro events) Now that my training programs are focused more on intensity than endurance.. they are more complicated and harder to remember. So now I take a permanent marker and write the more detailed programs on the back of an ols race number and stuff it in jersey pocket. Not only is it indestructible, it can be used again whenever said workout is repeated. I am the Martha Stewart of bike racing.
