I'm throwing a party in about a month - what should I serve that's easy? I'm running a half marathon that morn?

Ok - I'm running a half marathon for the first time ever the day of my party. Reason I want to throw a party is because 1.) husband and i have never thrown a big bash at our house (been there 4+ years); 2) my older (and favorite) sister will be in town because she's running the full marathon; 3) my entire family will be in town; 4) i feel like my husband and i have finally gotten out there and met enough people to actually have a reason to have a party at our house. i want what i make to be good but not too stressful since i have to run 13 miles that morning. we're getting two kegs too and several bottles of wine - probably will do lynchburg lemonade as well... along with soda, water, etc. for those that don't want to drink anything. any suggestions on drinks (some sort of punch??) and food that I could make? heavy appetizers (so we don't have to spend all night on the grill and we can just throw a bunch of stuff out on the table for people to munch on)?
