Max segment length

Both 10base2 (180 meters) and 10base5 (500 meters) would do the job, but neither are fast or robust. I tried to remain child-like, all I acheived was childish.

The 10Base2 or 10Base 5 is a good solution if you want to run coax but not many people do these days.

The TIA/EIA standard for UTP cable specifies a max lenght of 100M + 10% or 110 Meter. The 10% is due to variations in the cable NVP value (the speed that the data travels with respect to the speed of light)

In Europe, they actually don't care how long the cable is, as long as the delay for the data to reach the other end of the cable takes less than 555 nS, you're in the clear. The other parameter is attenuation, which these days is not an issue because the make cable so good these days.

You would be pushing it at 130 meters (20 meter longer than our standard) but you could give it a shot. The other solution is to install fiber with a media converter at each end, that should put you back too much.

The TIA/EIA-568-A/B standards explain the answer in very simple terms. 100M is the sum of all wires and cables in the link, not just from outlet to outlet. NO horizontal connection may exceed 90M. Test equipment used to test and certify cable installations must fail any link greater than the 90M horizontal connection limit.

So if you follow the advise that 100M limits allow for 110M runs, don't be surprized when no one will be allowing warranty claims for any problems (hardware or software) for operations which fail baseline installation standards.
