It always sounds a bit "slangy" to me, but a nice word for OP's context is... skedaddle - to depart quickly or hurriedly; run away . ...
another one I like (esp.
US usage, also somewhat informal, as are most apart from flee ) is... high-tail it out of here deriving from the raised tails of fleeing animals (as deer or rabbits) .
Similar terms include scarper, leg it, beat it, clear off .

In Northern English (e.g. Manchester, Liverpool), this phrase is quite common When those guys showed up, we legged it .
In US informal English there's also "skedaddle": When those guys showed up, we skedaddled outta there!
Perhaps more commonly you can always use an intensifier to impress upon the listener that you got out of there quickly:
When those guys showed up, we got the hell outta there!
