There are a couple of things that you need to know before you can attempt cornering. You must always extend your outside leg and lean into the corner. Also, keep your eyes focused on the farthest point of the corner as you turn and don't forget to brake BEFORE the turn!

Low-speed Turns

1. Keep a loose grip on the handlebars so that you can make any last minute changes if needed. Also, begin breaking before you hit the control to control your speed.
2. Try to find the smoothest way around by focusing as far ahead as possible. Don't worry about finding the fastest line, that's not needed when going at a low speed. Most importantly, follow a smooth curve.
3. Take caution on wet trails because it may be slippery. Especially large rocks or roots which can cause you to skid.
4. If you shift down one gear before leaving the corner, you will be able to pick up acceleration and regain your normal riding pace.

High-speed Turns

1. If you suddenly approach a sharp turn and are going really fast, try to slow down before entering the corner.
2. Take as wide of a turn as possible. This will give you more time to turn and make it around the corner. Remember to keep your outside leg extended.
3. As you are going through the turn, aim for the center of the apex and keep all of your weight on your outside leg to prevent from skidding.
4. While in the turn do not pull your brakes because this will cause you to lose control. Try leaning into the corner as well: this will help you continue through the corner.
5. Once you make it out of the corner, stand up and pedal hard until you have regained your speed. Keep in mind that someone or something could be just around the corner so proceed with caution.
