Learning descending skills is key when training for cycling. Once you've made it to the top you want to get down as fast and as safely as possible. Learn the best tips for descending on your bike right here. First of all - get in the drops. This will not only make you more aerodynamic, it will also lower your centre of gravity giving you more control. Remember to keep pedaling when you can ( not while cornering) so you keep your engine ticking over and don't get cold - the wind chill at speed can sap your warm very quickly.
As you corner ensure you have your inner pedal up - so you don't risk hitting it on the ground - and endeavour to angle the bike beneath you to maximise traction. Your line through the corner is extremely important for remaining safe as well as maximising speed. Approach wide and hit the apex of the corner. Looking where you want to go will give you great control - pay attention to this, it makes a huge difference. This will mean focusing past the corner and focusing further up the road the faster you are going.
Finally - although there is a lot to pay attention to - find a flow. The best descenders feel the descent and flow from corner to corner - this comes only with experience so go ride some hills so you can enjoy the descent.
