Why speed train for a marathon?
The interval training and tempo runs that we do as part of the CAR Training Program are intended to improve your physiological and mechanical efficiency as a runner. By incorporating speed work into your training, your body will improve its ability to utilize and deliver oxygen to the muscles that need it during exercise and you’ll be “waking up” your fast twitch muscle fibers that you don’t normally employ in your everyday running. The end result will be that running at any pace or distance, whether it be a mile or a marathon, will become easier as your body’s efficiency improves.
