I am running my first half-marathon in a week, any last week training advice?

Hey /r/running I am running my first half marathon on April 1st in Chicago on April 1st and would like to have some last week advice, I have been running about 18-20 miles a week along with cross training with on a stationary bicycle. I ran a 9.5 long on Sunday, the schedule I have been following calls for a 10 mile run tomorrow then rest and and 2 mile runs on Tuesday and Thursday leading up to the half.

I just want some last minute advice for this final week for thing like my last runs( such as is a 10 mile run really healthy a week out), nutrition and prep. The only other race I have done is a 5K 6 months ago. Any tips and advice would be appreciated. Thank-you
