50 yard freestyle?

im 14 years old and im a girl. im very small..i only weigh 80 lbs and im only 5'0 feet tall so i have room to grow..
i do a 50 yard freestyle in 29.2.
i have a HUGE meet today and i need to improve.
advice on how to get to a 27? i know i am capable.

take 3 breaths on the way down and 2 breaths on the way back!! DON'T breathe off your first stroke and do 4-6 FAST dolphin kicks! listen to your coach!!!! he knos u better than we do! Oh ya... crack yo moma or red neck jokes... rub the block 3 times to get the nerve endings on your hands so u can catch the water easiar

First pump yourself up behind the block... jump around and get the blood flowing so that when ever you jump off your already to go...

Second when diving off try to dive out more and not so deep, practice this in your warm-ups and ask your coach on how well it is...

Third do not breathe so much and when you do try to rotate your breathing....

Fourth try to pull with all your might as well as reach out to grab more water ....

Fifth make an "S" movement when pulling the water it helps you grab more...

Sixth GOOD LUCK YOU'LL DO GREAT!!!!!!

Since the meet is today--options are limited. Swim the race smart. One breath down, two breaths back, max. Your legs should be running 6-beat kicks per stroke the whole way, full speed. Strong streamlines off the wall. And half fun.

On the flip side, make sure your strokes are fast but stroke. You cannot let your arms run so fast that you miss your catch on the water, and start slipping. That will only slow you down. Strong kick, strong-steady-fast arms.
