HILLS!

Answer 5

What you are describing is Hill training, Hill training can be very benifical for building strength and speed.  The idea is to find a hill 600 - 800 meters in length (approx. ½ mile), and run up the hill at tempo pace which is just a touch slower then what you would deem your race pace.  At the top of the hill either walk or slow jog back down and repeat.  

Depending on the distance you are trying to achieve, you may want to start at about 3 repeats and work yourself up to about 10.  You only want to do this type of work out once per week, but you will benefit greatly on runs not only being faster but able to take hills better.

Answer 6

uphill is awsome because anything tht causes resitsance is awsome

Answer 7

i heard sprinting uphill is the best to develop fast twitch muscle fober to increase speed. And Running downhill does nothing but f*** up your shins and knees

Answer 8

just a note: when you run down hill, lean back slightly and concentrate on going slowly and using a good stride to keep from getting shin splints and such. When you run uphill, sprint up it. It's like intervals with hills! brilliant.
