Japanese Steak House

I just got home from a Japanese Steak House. I have a 5K run tomorrow morning. Eating Japanese food hours before a run was definitely a bad choice. Naturally I ordered a big meal and ate all of it. The amount of rice they gave me could have fed a family of 4. I ate it all. Then they gave me steak and chicken. It's 11:18PM and my run is in less than 9 hours. I am so full right now I can't even think. I think tomorrows 5K run is going to turn into a 5K walk. I have no idea how I'm going to survive!
