Not sure what to do next

So your next triathlon will be about a year away?  What distance?  Can you narrow done the month?

And it sounds like running is your limiter?

I looked at your last month of training, so it seems that your running hasn't repeatably exceeded about 35 minutes.  So I would recommend the 4-7 hr 20 week winter maintenance plan.  The first week or two may be light, use it to recharge from your season.  But this plan should see you getting to 50 minutes to 1 hour runs a few times.    It is also 3x per sport so hitting this plan with consistency will help you a lot.

You can also add in a 4rth short/medium distance run to help get that 'run durability.  But you would only add in a 4rth run until after you are consistently hitting 3 runs per the plan over several weeks.

THEN if you are comfortably running through the end of the plan, it could set you up well for the 8 week run focused plan.  That is about 5 runs per week (though you will want to build up to that before starting it over several weeks) and it starts at 30-50 minutes of running per week, 5x a week and builds to about 1.5 hrs.  But first you need to do the above 4-7 hr plan to get that running up and being consistent.

After that first plan or both of them, we can later discuss transitioning into a sprint race plan...maybe an intermediate plan.
