What accuracy requirements do you have.  This could be easy or impossible.

Don't spend to much money distributing 1PPS because you can have it
any place you want for the cost of a GPS receiver.  A second GPS
receiver is likely cheaper than the cost of 120 meters of cable plus
the cable drivers and receivers.  Even if you build the cable system
you'd need to test it which adds more time and cost.  GPS is so cheap
you can place them where needed.
