Okay. I am the top runner for 800 meter(half a mile) run at my school. I will be running cross country, and I will be beast at it. (The coach is practically begging me to join).Since you are running cross country, you will be running around 2 miles each meet. To train for this, you need to be able to run at a good pace throughout the whole race To train for this, you should run almost every day, around two miles each day. Eat healthy foods, and carbs. You should gradually increase your mileage, and endurance. Make sure every time you run you try to lower your time a bit. Also, running shoes are key. Make sure they are very lightweight. There are also long distance spikes you can use. They look like long, chunky needles. DO NOT get the short distance spikes, After which owns really help. They look like triangles. After a month or two, you should be ready for cross-country season. Good luck!
First try to run as long as possible u don't have to go fast then a few weeks after start running a mile as fast as u can and try to a fast mile and just keep on building it up (and please click on the star under my picture to support the fight against cancer and each question u answer gives 25 cents to finding a cure)
You need to remember to be consistent and persistent. By consistency I mean running often, maintaining a healthy diet, and stretching often too so your muscles won't get too tight. By persistency I mean being determined and having goals. Running is a very easy concept but that doesn't mean it's always easy to do. Honestly, you could be a terrible athlete but do really well at running though if you're persistent, and competitive enough.
