The tales grew bigger as the week drew to a close. Some warned that the Tennessee River was filled with catfish big enough to be mistaken for submerged cars--others said we should be leery of leeches (thanks M.). The most intimidating though, was a tale about alligator gar . . . which look like this:

(no, we do not know the man in the picture.)
There were about 1200 participants in this race, which started by age group--with 20-29 going last. So J. and I were in the last 250 people to start the race. After a bit of rain waiting to start, we finally got our turn around 8:30 (first starters jumped in the river @ 7:30).
The water clarity was nill, but it felt great compared to salt water and stagnant state park lake water. Temp was about 82 degrees. Didn't encounter any signs of wildlife along the swim--no catfish, leeches, or alligator gar--thank goodness. I'm sure they were lurking and watching with curiosity from the depths.
The weather didn't let up for the bike portion and for the first time in my life I rode on a bicycle right next to an 18-wheeler (the bike course was on a Hwy similar to 280 but was raised like an Interstate). With buckets of stinging rain falling, blowing wind, and huge waves of water off an 18-wheeler (D., remember how you used to wet the entire dock down with water at the lake--just like that) we were WET. Lightning and thunder accompanied which made us all pedal a little faster I think.
Swim (.93 of a mile), check. Bike (26 miles), check. Run (6.2 miles) . . . can't we just call it a day.
We both did great on the first two events and struggled through the run ( a 3.1 mile out and 3.1 mile back along the river). Luckily the clouds hung around and we were able to finish before all of that water from the storm turned into steam.
Overall experience: Exhausting and fun. Enjoyed hanging w/ fellow triathletes . . . results and pics to come.
Downside . . . a wee bit tired and sore. Upside . . . Olympic distance conquered (or at least accomplished ;)
