My legs, arms, and core are extremely swollen. I feel like I am going to burst. I am normally 140 lbs, but look like I am about 200. I am sure it is some type of water retention, but was wondering if this is normal at all. I have not done any activity since the race and my diet has been pretty sub optimal.

I am not a doctor but if I were you I would head to the hospital , just to double check everything…to be safe.
Keep us posted. Congrats on your finish buddy !
Odd - maybe you should see a doc…have you been able to get off the potty? If so…maybe reconsider…
Go see a doc please
please go see a Doctor, and if you can try to remember exactly what you did consume in the processof the race, the Doc will need to know this. I had complete body swelling after a race that lasted a wee bit too long and ended up with slight swelling on the brain. The edema altered my thinking capacity to the extent I didn’t even know what was going on–don’t let this be you, I am still dealing with eye issues, I walked away with minimal problems.
They have easy diuretics that will help to take the swelling off–but not something you would want to self-administer there are way too many variables to list…some of them life threatning. Get your butt to the Doc.
If you haven’t pee’d in a significant amount of time go to the ER NOW.
I forgot something else that is way important==if you are having trouble breathing/heart palpatations or wheezing noises when trying to climb stairs—that is also ER material which is where extensive swelling can result if not careful.
The edema altered my thinking capacity to the extent
Is that why you do week long races? 
This happened to me the night of/after my IM race, but not 4 day’s after. I’d head to the Dr. to get things checked up.
I woke up 2 hours after falling asleep only to be drenched in sweat and swollen all over. If I had thermometer, I’d bet I had a temperature… I waddled down to the ice machine and filled 3 garbage bags full of ice. I laid in bed for two hours with a bag on each thigh/groin area and another on the head/back of the neck. 2:30am rolled around and I finally felt like I had things under control. Sort of a scary situation, since I was by myself.
See your doc - one of the common sequelae of endurance sports (often seen in marathons) is hyponatremia - low sodium levels, where electrolyte replacement doesn’t keep up with electrolyte loss, and increasing thirst leads to intake of water or too-dilute electrolyte fluid. Can cause a lot of strange symptoms and signs, one of which can be generalized edema . Increasing attention being paid by medical community to this, especially following a couple of articles in New England Journal of Medicine in the last year.
