My default response would be running it in conduit, it keeps the
rodents off of it, and the individual wires are usually cheaper than
the bundle, off-setting at least part of the cost of the conduit.

Depending on how accurate the 140' measurement is, you're also close to
500' for the three conductors (reduced size ground) so you may get a
better price buying a full spool. Still need to buy just 140' or so of
the smaller wire for the ground.
