As long as you take  10 hours rest before next shift  , your legal.  Just doing run ups is ok, unless your so tired you think you going to hot Start etc  or do something that could get someone hurt .. No different than getting in your car after long day and driving home . A lot of pilots that stay in company housing do that on last day of hitch and then have 6 hour plus drive home And if tired they don't go.

If it s legal, the rest is common sense and personal responsibility... Both of which are dying traits these days.
