I am late posting this one. Drawing made from a picture from my last race.
This is yours truly at mile ... dunno ... maybe 17 or so ... of the Hartford marathon. No, I do not have a woden leg, but I am sure that by that time, my legs did feel like wood. Or concrete.
Whenever I check the links posted for illustrations, I feel like giving up. I draw like a three years old...people make such neat stuff over there it's amazing.
