Danny Dreyer, author of Chi Running, a revolutionary book that focuses on running technique to not only heal and prevent injuries, but also to help you run faster, has started to syndicate some extremely useful tips on Amazon.com. Here’s a couple of tips that Danny has already offered:

Running Form
“The longer the distance you run, the more amount of time you’ll need to spend landing on your midfoot instead of your forefoot (as sprinters do). If you spend too much time up on your toes, the small muscles of your legs will become overworked and/or over trained and you could end up being a candidate for some form of overuse injury of the lower leg (shin splints, calf pulls, achilles tendonitis, plantar fasciitis, and even metatarsal fractures).”
Danny Dreyer, Chi Running.

Another useful tip from Danny:

Whether to breathe through the nose or mouth
“As for breathing, it is best to work your way towards breathing through your nose as it gets the air deeper into your lungs than mouth breathing. Nose-breathing also stimulates nerve endings in your head as the air passes through the sinus passages, which help to relax the brain. In the winter it pre-heats and filters the air going into your lungs. Practice nose breathing for short periods at slower speeds and you’ll gradually be able to nose breathe at the faster speeds. I can run at a 7:30 pace comfortably with my mouth closed at this point and it’s very relaxing.”
