Solid core, one wire to travel around like you say, multiple or stranded wire has more sufaces for the cage effect to get mucked up, altho it usually bends with out breaking opposed to solid core, it does not do well with network signaling. You will need switches, not hubs, every 100 meters and at least one repeater to do the full 700.
