Olympic Plan with max running at 6.4 miles...normal?

Depends.  Did you choose a beginner or intermediate plan?  How many week was your plan and what run pace did you put in?

I'd run at least 6.5.

It isn't going to kill your plan to mix in a 10 miler, or max out at 5 miles.  Make the plan work for you.

If it's a beginner plan, at the oly level it will train you for your long run in peak week to your run race distance.  This is for safety as it assumes that you are new to the volume and have not exceeded those levels yet.  AND about 2 runs per week, based off of personal experience, I don't easily build volume on 2 runs per week...2 runs per week is a good maintenance level but if you are building new volume throughout the plan, 3 days per week of running will be better.

You can play with the 'paces' to raise or lower your running volume, though be careful if this is new distance.

Intermediate and advanced oly plans do have overdistance training in the run. 

If you want to recheck your paces, yes, recreate the plan.

*If you are a runner, and this volume is not new, adjust your pace and/or the 'run distance' to increase the weekly mileage to what you are comfortable at.

It wasn't intended to be "safely complete the distance", but maybe if my pace is too slow it ends up being that way anyway. I guess "beginner" doesn't help...wish I could set the swim portion at beginner and the rest at intermediate because I do feel like a beginner in the swim. Perhaps it calculates based on time running, so if I run a 10 min/mile I'm only training to about 6.5 miles and if I train at a 9min pace it'll have me run a further distance...

I've done 2 half marathons that worked out great based on 2 days of running (I also teach 3 strength training/weightlifting classes, 2 core classes and 2 spin/RPM classes per week). My times kept with my expectations (1:47). That's why I only run 2 days....my "work" has me "training" 6 hrs week and then I'm adding in all of this other additional training. I typically use my spin classes as my bike training, but try to get out on the road once a week to keep the "feel" of the road since it does work muscles differently.

Since the race isn't until Memorial Day I guess I'll go back in and start manipulating some numbers a bit.

Julie, two things to try:

1 - Look at the Intermediate level Oly plan.  If the swim is too much (as we like overdistance in the swim), you can back down the race yardage on the swim.

Or, 2 - Do the beginner plan, up the run race distance until you feel it is more in line with your current running volume.

Let me know if this helps or not, there are a lot of ways to 'tweak' the plan as you create it.

OK, so I went back in and made a new plan and moved my pace down to 9min/mile....HUGE difference! Now it has me running 8.4 miles as my longest run which makes much more sense to me. So I don't know if I just had a 10 min pace listed, but that small factor plays a huge role in how it'll dictate you're training. So now I feel much better with what it has me doing. Now my longest bike distance is 27.50 miles which I don't know if it should be higher or not, but I feel pretty comfortable with bike stuff...BTW, I don't like to follow the minutes as much as the distance if you haven't figured that out

Thanks so much for all your input....definitely helped me out!

I agree with the other post that 2 times per week is ok for maintenance but in my experience, 8 full and 9 Halfs it takes at least 3 if not 4 runs per week to truly build a solid base. JMHO

How long will 6.4 miles take you? This is all relative to what your situation is and the parameters you put into the custom plan creator. If you are going to run 2x per week, you certainly aren't going to get a 10 mile run in there. At minimum you should be running 3x per week for MAINTENANCE. If you want to improve, you need to run 4, 5, or more times per week. 

First thing you need to look at are your needs and how you can fulfill them. If your run is your weakness, then you need to run more. If you are going to run more, you plan will have a run longer than 6.4 miles.  

Hope that makes sense. 

Sounds like you are doing plenty and definitely need to put family first. 

So, my suggestion would be to aqua jog - do this immediately before or after your swim session and it can be as short as 10-15 minutes with intensity - 30 secs on / 15 secs off - try it, it's hard. You'll get your HR up, no stress on the joints/ligaments. It's efficient since you are already in the pool and it will help your running without question. I do it 2x a week after I swim. It helps. 

Good luck and be careful with those injuries. Best of luck in your 2012 race season.
