I'll try anything once.
After seeing it on a blog while looking for the cartoon below, I decided I would challenge myself to walk 100 miles. I have no concept of how long this will take. I will just be amazed if I actually complete it.
I will allow myself to count 'real' walked miles as well as 'elliptical' miles. So, the fact that I walked 2 miles yesterday and did one mile on the elliptical this morning, I am already 3 miles into it.
But as is the case with any "ceremonious event", let's hold all the applause until the end.
