As you have probably already guessed, running in water is very different than running on land. The resistance training that you receive improves the heart, increases lung capacity, and builds muscles. When you return to running on land, you may find yourself running longer and faster. All these benefits from water training significantly increase your endurance. Simply put, if you engage in Water Running Therapy you’ll find it easier to increase your training when you revert to land running, and you will notice that you actually progressed in your training even though you took some time off of your land running. Since endurance is a major part of training for long-distance races like marathons and ultra-marathons, many ultra-marathoners are including Water Running Therapy into their training regimen.
