The specific types of workouts included are track repeats, hill running, bricks, and fartlicks that will help you build strength, endurance and learn proper form.
Bobby McGee has worked with me since 2005 and helped me prepare for the 2008 Olympic Games. Since I started working with Bobby, he has greatly improved my running technique by introducing me to a variety of drills. Not only has he helped me with the physical aspect of training, but he has also helped me with my mental approach to racing. Bobby teaches athletes and coaches mental techniques that can be used to prepare athletes to compete at their best. You can check out Bobby's website at http://www.bobbymcgee.com/.
