"This is a quote that has nothing to do with running." - Song you've never heard, Band you've never heard of.
This first paragraph is all background. It tells about my history with this particular race, something about what kind of shape I'm in and details my preparation before the race. If someone shows up later in the post, this is where foreshadowing introduces them at the starting line. The weather, if relevant, gets a mention.
This is the beginning of the race and describes the course. First, there's an overview. Then there's a more minute description of important features in the order they're encountered.
This is the main body of the discourse and details the progress of the day. There will be things said by other runners. There will be encounters with wildlife, both flora and fauna. There will be a few mentions of distances and times.
This is where it all goes wrong. I start with ominous hints of body aches. I make a wrong turn or two. Then I mention falling, sometimes repeatedly, usually calamitously. Something happens that never, ever, happens to anyone else. I make some literary allusion, to look smart.
This penultimate paragraph describes the end of the race and a finish time (if I finish). Then, maybe, some of the things that go on post-race.
Here I end with what other people did and what I learned on the way and some vague thoughts about the next race on the schedule.
So. The next race report will have to be different. Iambic pentameter?
