Did 8x400 with the following splits
74,73,73,73,73,74,73,70
All with 1:30 rest besides 2 that had about a 1:45. Was not using it as a predictor workout but want to see if it means anything. Started to get a little thought after about the 5th rep but still felt very in control the whole time. Does this mean anything?
PR is 5:06 from about a month ago
