brand new, started training 3 weeks ago

Oh, I missed the bit about 'competitive times'.  Are you asking because you want to be competitive?

The plan you have is not particularly well suited for top performance in a triathlon.  In general, people are not going to perform even close to their potential on two swims, 2 bikes, and 2 runs per week.

And I agree with the poster who suggested that the Friday run is weird.  It is.  In fact -- setting aside the weight training (no comment there...) -- all of the tri-related workouts are weird, and probably not what is going to prepare you best for the race.  Did you make this plan up, or get it from somewhere?

whats weird about the running?

the run in the competition is 5k, im guessing the sets before the 5k at the end are to exhaust you to somewhat simulate the real thing

On the assumption that you will start with 2x/week for each discipline, and the assumption that you are focusing on doing well in the triathlon, and the assumption that you are relatively new to this, here's what a more or less typical week could look like for you.  I'm being deliberately vague about what counts as 'hard' and 'easy' because you don't need to worry about hitting precise zones at first.  You just need to get S/B/R-ing consistently.  I don't in any way propose this to be your plan -- the point is just to illustrate the difference between what you posted and what a typical beginning regimen looks like.

MON:  Off

TUE:* Bike.  Warm up for 10-15 minutes then do 4x(3 minutes hard/1 minute easy), working up to 6x(4 minutes hard/1 minute easy).  Cool down.

* Swim:  10x50 warmup (easy); 10x50 as drill 25/swim 25; 12x100 moderately hard to hard, with 10-15s rest between; 200 cool down.

WED: Off

THU:  Swim:  10x50 warmup (easy); 10x50 as drill 25/swim 25; 3x400 moderately hard to hard, with 30s rest between; 200 cool down.

FRI:  Run 3 miles easy (conversational pace).

SAT: Bike.  Warmup 10-15 minutes then bike moderately hard for 30 minutes, working up to an hour.  Cool down 5-10 minutes.  Once or twice before the race, run 1 mile immediately after the ride (aka 'a brick').

SUN: Run 5 miles easy, incorporating 5x30s strides.  If you feel good, pick up the pace a little for the final mile.

(The part of this (non!) 'plan' that makes me cringe the most is the 2x/week running.  You should really try for three, in which case I'd put an easy 3 mile run on Wednesday.)

See the difference(s)?

As others said, look at some of the free (or paid) plans out there to get a better idea.  Find plans written by sources with a proven record in triathlon.

You don't need to be running hard intervals right now.  (And if you were running hard intervals, the set that you wrote down would not be the place to start.  You need to have many many miles under your legs before you could attempt that set and hit anything like the intensities needed for the set to be truly beneficial to you.)  

In fact, running hard intervals is probably the worst thing you could be doing.  It will almost guarantee that you get injured.

Focus on consistency.  If you can run 3 times per week, that's a good start.  If you want to get serious about running up to your potential, build slowly.  (The general recommendation is 10% per week, but it's more important to listen to your body.)

The idea that you should simulate race conditions as a regular part of your training is understandable, but misguided.  Doing so will just lower the quality of your training.  There is a place for race simulations, but that place is once or twice 3-4 weeks (or so) prior to the race, not weekly.
