Physiologically, it would be smart to run. Your leg muscles and aerobic system will be unaffected by the lack of sleep. It's the meta-niteals in your cerebrum that are affected most by lack of sleep. Running doesn't affect these unless you run for more than 2 hours, or if you're over 40 about 90 minutes or if you're over 60 about 60 minutes.
Fwiw, I just made all the up. Do what you want.
