It seems to me like doing long run followed by long bike the next day would trash my legs. I think I would just alternate weeks for the long run and long bike. So that one week would be long run on Saturday, easy ride Sunday. The following, easy run Saturday, long bike Sunday.

Either way, you are getting your endurance training so you don't necessarily need to fit in every single training session for both.

And, I see all your run workouts are right in a row: Th, F, Sat. Could you alternate that? Maybe long bike on Saturday and then run on Sunday? My body doesn't handle running like that. I can only do two days of running before I need to do something else to be productive.

I am no expert, that's just my two cents.
