Thanks, Pete, thanks Duane. I appreciate your responses. With another half marathon to measure in a few days, I was not too keen on going back to my 10K for another measure. So, this is good news.
Last week, Bob Thurston and I measured the National Marathon in D.C., along with parts of the accompanying half marathon. Watching Bob's techniques of piecing together parts of the half marathon gave me the courage to go ahead and try something similar for my 10K when the need arose. I wanted to ask Bob about my methodology for the 10K, but he was away on an out-of-town trip, so I posted here. BTW, Bob is meticulous as can be. He is a great teacher. A total delight to work with. I am grateful to him for the opportunity to measure with him.
Pete, I think your idea of diagramming what I did makes good sense for the purpose of giving John Sissala or Bob Thurston - whoever reviews my work - a clear picture of the redesign documentation.
Thanks again.
