50m freestyle Help!!!

Getting to 24 is going to take you a long time. I think you have the conditioning down for 50 meters. Lots of effort, and your speed doesn't fade until the very end. If you can shorten the race by being more efficient, you'll barely fade at all. It looks like you are slipping in the water with your arm stroke, and rushing the catch. You can improve this at the same time as working on your streamline by doing lots of catch drills. I think it's best to do these while wearing fins, so that you can work with a fast flow of water, and also improve your kick at the same time. Do flutter kick on your stomach with your arms extended in front of you but not locked in a streamline. Tilt one wrist slightly downward, and allow the water to push against the back of your hand. Then bring the wrist back up and do it with the other wrist. Once you're used to the pressure on the back of your hand, allow the pressure to push your forearm until it's completely vertical, with your elbow still at the surface. Do this with alternating arms. It's kind of like doggy paddle, except you aren't pulling. Just let each forearm slide into a vertical position, and then straighten it back out. That position, with your elbow above your wrist, is the most powerful position for the freestyle stroke. Once you feel comfortable with the first drill I describe, start engaging the water with a strong pull in this position. Just quick short pulses of power at first, recovering underwater like in the first drill. Then work up to the full stroke with an over-the-water recovery. Instead of focusing on the movement of your hand, imagine pulling your elbow to your side. The strongest muscles on your upper body are the ones that bring your elbow to your side, and you want to use them as much as possible. That's the drill progression I like to use personally for a strong catch. I hope it works for you, and please ask questions if anything is unclear.
