Apparently your odds of even having the option of spending the rest of your life on the run are fairly tepid. Both that source and others give figures north of 90% for recapture in a year or less; with many escapees lasting only days.
The correctional types obviously aren’t thrilled; and things can get a lot more serious if it’s someone with a particularly dire criminal history or who uses violence during either the escape or the subsequent evasion attempts; but at the level of minimum security it seems like escape is more of a terrible idea than a terribly difficult one.
