As you know, Alice and I will be participating in the Disneyland Half Marathon on September 4, 2011.
This year, as with the Los Angeles Marathon on March 20th I will be using Jeff Galloway's Run/Walk/Run method. I have been using his training methods since my last Disneyland Half and have experienced increased fitness and NO injuries.
In this video, Jeff demonstrates the cadence drill which combines physical and mental training to increase speed. It is common sense that increasing the number of steps you take while running will make you faster. Performing this :30 second interval training, 4 -- 8 times, once a week , will help you accomplish your goal.
