Did this at 9:20 Monday night after a track meet. Ate a hotdog no bun a bag of chips and a poweraid at 4:15 that was the last time I ate. I am worn out. My fire just was not there. My back was also hurting the whole time. By the third round it was hampering my form. I grabbed the belt for the last round. Not good. Oh well I got one in.
