You should probably do some pulling exercises.... pullups, rowing, etc. as you WILL get some nice shoulder imbalances and pain if you keep it up without any upper body pulling work.
Are you training for endurance races like running or something? If that's your priority you can try adding some more strength work BUT if it makes you regress (overreaching) then you'll have to back off.
Otherwise, I mean I don't know why you're doing so much endurance work when you could do something like CF or some type of hybrid program and still have a fair amount of endurance with good increases in strength.
What are your lift numbers anyway?
