Thats the truth.
At Youth Nationals I showed up 20 minutes late to the staging area and ran a pr by 2 seconds in the 800m. At Nike Outdoor they were about to start the race and my team was on the otherside of the track so they had to wait for us and I ran a relay pr by 4 seconds in the 800m. At one of the more local meets I was one of the first to report and ran 2 seconds slower than my pr in the 800.
