Block heater cord length/gauge

[Jme24]

Hey guys got a quick question the temps are supposed to be in the single digits next week and I live in barracks on ft drum were the ability to plug my truck in is not an option until I recently found a outlet on a nearby gym. Unfortunately the outlet is about 175 feet away. Will I be alright running 14 gauge extension cord that far or am I **** out of luck. My truck 02 7.3 hates these single digit starts and sometimes takes me a while to get her stated.

Thanks

Prob too far but if you try it use at least a 10 ga cord
