1) Speed
These workouts are short fast and high intensity. The goal of these workouts are to increase the maximum speed that you can run and how long you can sustain it. A good example of a speed run would be 3 400 yard sprints.
2) Distance
These workouts are long and slow and low intensity. The goal of these workouts are to increase the maximum distance you could jog. An example of a distance run would be a 4-mile jog through your neighborhood.
3) Recovery
These workouts are both slow and short and have one purpose: to rest after a hard workout the day before while still getting running in. These workouts should be so easy that you don't even feel like you are working out. An example of this would be a 1.5 mile run on grass slowly.
4) Conditioning
This workout is not technically running but is vital to getting in shape. The goal of this workout is to condition the rest of your body to run without running. These workouts are for all levels and can be any intensity you want. Some good examples of conditioning include squats, weights, pushups, lunges, yoga, and stretching.
I will be adding training plans every week on Mondays that incorporate these types of running workouts and are organized by the type of training you are looking for.
