KYROCKET (My Man!),
Good luck with the planning. I’ve done a few up here in the D.C./Richmond area. Here are links to a couple that I’ve done:

In the for-whatever-its-worth dept., I actually liked both races. The April time for the Cure Autism Now race is a good one around here; you can do a shakedown on your equipment in a race environment before bigger races (such as the local Columbia tri) come along on the schedule. It also has the distinction of being the only triathlon in the D.C. area that is inside the Beltway (although that probably says more about the difficulty of road closings than anything else).
Of the two, the CAN race has the better swim set-up, but they have the luxury of using 3 (count 'em) pools at the Bethesda-Chevy Chase “Y”. Obviously, having 3 pools is unique. The 2 outdoor pools are also heated. So, they can basically let you swim your 500 in a half lane alongside someone else. This is better than the “snake” course format used by the Richmond race, but they only have one pool. Seeding the swimmers if you have to use a “snake” format is the hardest part, I think, since all it takes is for one person to put the wrong time in and you’ve got folks stacked up behind trying to pass safely (if that is possible) with people coming back down the lane on the other side.
I like the swim distance at CAN (500 yds) and the bike/run distances at 3Sports (20K bike and 5k run). That bike distance is about half the usual Oly bike, which sounds about right, but I know is shorter than some other sprints around. Do it swim/bike/run. These were both timed races, vs. total distance.
At each race, they staged the transition area in a portion of the parking lot, so you would move from the pool out to the lot, put on your bike gear and ride, then come back, rack your bike, and head out for the run.
I haven’t done these other races, but here are a couple of others I have heard of, one of which was staged out of a health club. But notice, they went in each case with a “real” bike/run course vs. something indoors on trainers …

Hope some of that helps.
