Four AWG #1 conductors in 2-1/2 inch EMT. 50 ft of conduit, four 90 deg.
elbows.

Is this combination reasonable to pull with some lubricant? Or should I
plan
some "pull boxes" in this run?

Only one 90 degree bend is ok. But can't you get inspection elbows. These
have a removeable cover on the side of the elbow that allows cables to be
pulled out then fed back in again.
