Should I have a PowerBar Performance bar before my 400m race?

No, the 400m will tap your energy store for the race, but your body will have enough energy for a short sprint. But what will help you the most is a good nights rest and stay out of the Sun so it won't zap your energy while waiting for your run event. Stay warm and hydrated.

Know what time your racing and warm-up and stretch just before it's you time. My coach used to give us a Boost energy drink about an hour before we ran the mile run at meets, but that was because the mile was normally the last event and we were waiting a long time without eating. Good luck on the track!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
