Adductor Strain + HIM

Hi Everyone, looking for some advice beyond "go see a DR" because I am going to do that, but he is NOT active like most here and may/would not understand.  I have an adductor strain and have seen a physiotherapist about it, he gave me some stretches which I did and it was feeling better, so good in fact that I went back and played soccer BIG MISTAKE...now it's hurting again like when I climb into bed and try and lift the leg etc.  I went for a bike ride today and can tell it's there, but can still ride well, however, got off the bike and was supposed to turn it into a Brick and that was NOT happening.  Pain across the lower abdomen etc, abandoned the run and came home. 

So...here's my question:  I am signed up for the B2B in October and right in the middle of my training.  This is my first HIM, and I'm wondering what I should do with my training as I work through this?  Should I just keep up the bike and swim and walk, stretch etc and rely on the fitness from B&S to carry me through the run.  I have run the 1/2 mary distance, but only 1x.  I can run 12-15k no problem (when I'm healthy) and not looking to podium, just wanna finish.
