50 Free and 100 Back in the morning!

I'm looking forward to the 50 free. I think I can bust out a 24 low, perhaps a 23 high. My goal will be to break 24.00. Its a lofty goal but we shall see. It will need to be a flawless swim. I will have 30 minutes or less to cool down and prepare for the 100 back. It will be my first long course 100 back in a very long time. Over a year and a half. I fear it a bit, especially coming off my 50 free. Good swimmers wouldn't consider that a tough turnaround but that would be assuming I'm in some sort of athletic shape. My goal is to break 1:01.00. Again, that will be tough for me. I've had trouble cranking it up in backstroke lately so anticipate some difficulties in this race especially. Still looking forward to some great racing! To my competition: thank you for the motivation!
