To run tonight or not???

I am doing a 10 mile trail run tomorrow.  I really would like to run tonight but I am not so sure I should.  Will it hurt my performance tom? any advice would be great.

 IF you go, again IF -- take it easy!!  I would say a 1-2 mile probably wouldn't really hurt you too much if you absolutely need to.  The strangest thing for many of us is the taper.  If it was me I'd do a nice good carbo-loaded meal tonight (pasta or rice) and just relax.  Save all you're energy for tomorrow's race and enjoy the nice weather tonight!

I try not to run two days in a row. My body can't take it.

The exception is that I run 2x on Tues. But that's just how my schedule worked out and I haven't been able to fix it.
