All you can or should do is warm up thoroughly in a relaxed manner with very careful stretching to see how you feel. There is no point in testing anything at this point as all you would do is loose one day you have for recovery. If you feel good now, the test will come in the warm-up for the meet itself. Give yourself some extra time to get ready and be sure NOT to overstretch before the speed portion of the warm up. A series of progressive accelerations should let you know if you are ok to race. If you have doubts then- scrub it.
