Becoming stronger, particularly in your legs will greatly reduce the chances that you will incur injury when you start speed training. Speed workouts can be highly taxing and damaging on your body if you are not ready for them. So the goal is to create strong muscles that can withstand the ardors of speed sessions that are key in learning how to run faster.
Without first having that strength in your legs you are begging for a host of injuries not limited to shin splints and chronic inflammation.
HOW TO BECOME STRONGER + Resources:
Block off at least a month to preferably two months of training to focus on adding in hill workouts and strength training sessions at least once to twice a week. This will set you for your next phase of training: speed work!
After you have built strength in your leg muscles through a series of hill training sessions or strength training workouts (1-2 months) you will be ready to start adding in a weekly (or at the most bi-weekly) speed workout. There are different kinds of speed workouts for you to do! So first read our page on how to speed train and then go from there!
