Q: Instead of looking at the whole, break down the mile into parts; it's a lot more manageable to work on your skills in 90-second chunks. When you get to that 90-second 1⁄4 mile (0.4 km), start working on your 1/2. When you can do a half mile around 3 minutes, you'll be jazzed to see if you can keep the pace. So skip the unnecessary duress on your knees and break it into pieces. Psychologically, your brain looks at that 6-minute mile and goes wah-ha-ha-ha-ait a second. 6 minutes? Are you crazy? But 90 seconds of going all out? ...Why not? That stands for High-Intensity Interval Training and it's quite possibly one of the best things you can do for your mile time and for your overall athletic performance. It's like sprints (as discussed above), but repetitive and cyclical. For example, you might run all out for one minute, rest for one minute, and repeat for 8 or so cycles. Eventually, that 6-minute mile seems like a leisurely walk in the park. As you get better at it, up the intense periods. Go to 75 seconds of running and after that, 45 seconds of rest. Keep going in small increments until you're up to two 3-minute chunks. Then all you have to do is piece them together! When you train, run more than just that goal of 1 mile (1.6 km). Speed isn't the only key -- endurance will get you going, too. So take a break from your speed training and go for a nice, long jog to break up your running routine. When you routinely run 5 miles (8.0 km), the 1 mile (1.6 km) poses way less of a threat. Use it as a reason to change up your environment. Move your run to the gym, your home treadmill, or a different trail outside. It's about keeping your mind fresh, too! The third player here, in addition to endurance and speed, is strength. To propel your body at this speed, you're gonna need to build it up. Jogging the track for miles won't do you as many favors as a hilly track will! Getting your heart rate up and your muscles earning it on inclined terrain primes them to take you to the next level when the ground is flat. This is a good excuse to change up your routine, too. It's easy to hit the gym or your favorite track at the beginning, but then you inevitably get bored with it and hit autopilot, never reaching your goals. Spice it up by finding a hillier route to keep your mind in the speed zone, too. Learn to run a 1⁄4 mile (0.4 km) in 1:30, then a 1⁄2 mile (0.8 km) in 3:00, then a 3⁄4 mile (1.2 km) in 4:30, and finally try to reach the goal of a 6 minute mile. Find a route where you can easily see the distance markers, grab your stopwatch, and see where your feet take you. It's the only way to know how lofty your goals are -- or how attainable. That being said, don't feel the need to do this every day. Work on your skills for the majority of the week and then see how far you've come. If you do it every day, it'll just become a drag. If that 6-minute goal is because you're a competitive runner, there's some science that can help you get ahead of the pack and get you to the finish line sooner:  Start strong. Unless you're playing the dark horse card, you don't want the pressure of making some ultimate comeback. Hang near the front group initially so you aren't facing a mob of obstacles in front of you. But don't feel the pressure to be in the lead at first. That person sets the pace, breaks the wind, and feels an enormous amount of pressure from all the people running at their heels. They'll get tired eventually and that's when you make your break for it. Make sure to run your own race. The worst mistake you can make in a middle to long distance race is in the first minute; that is, going out too fast. If you're running on a track, pass on the straights. If you try to make a go of passing the runner in front of you on a curve, you're actually running a bit further to get around that person. Just a waste of energy, really. Push yourself in the third lap. Deepen your breathing, smooth out your stride, and push yourself a little more. Your mind will tell you to stop long before your body makes you. If you push yourself a little more than the first two laps here, then your pace will remain constant or improve. You need to feel like you are running faster in the third lap for you to maintain your pace. Also, it is much easier to push yourself to your limits in the last lap, so if you push yourself a little here, it will only improve your time. Once you can see the finish line, you can almost always find the drive to finish strong. Focus on your form, breathing, and what's in front of you. Also, once you start your finishing kick, focus on still maintaining form and driving your knees a little higher. Do NOT focus on your crowd of adoring fans, your coach, or your feet. Keep your head straight and your eyes on the prize and don't get distracted. A second's look could make or break your time.
A: Work on your 1⁄4 and 1⁄2 mile (0.4 and 0.8 km). HIIT it. Work on your endurance with long-distance running. Run hills. Start training for time. If you're racing, keep a few things in mind.

Q: This will show you which apps are taking up the most space.  Doing so will reset that app's cached data, which will clear up some space. You may need to repeat this process for multiple apps. Some Androids allow you to clear all apps' caches at once from the Storage section of the Settings app. If this option is available, you'll see a Cached option here; tapping it will give you the option of clearing all cached data.
A:
Open the Settings app. Tap Apps. Tap ⋮. Tap Sort by size. Tap an app. Tap Clear Cache.
