"Runner's High" - Summer Endurance Program


“Runner’s High” is TNT’s summer endurance program. This is a 6 session long endurance program designed for you to improve your endurance and become a better runner. This running program will be tailored to your level to find a challenging pace and distance. This is open to all levels of runners as well as members & non-members. The workouts will not be held at the gym but off-site at tracks and trails around the local area. This will ensure more variety, accurate distances, and a chance to try something new and exciting.

The class structure will include dynamic warm-ups, stability exercises, mobility for running, technique training, and targeted interval training. Improving your mechanics will make running more effortless, enjoyable, and reduce the risk of injury. The targeted pacing intervals will give you very efficient training results. Interval training is a great way to improve your condition, running capacity, and weight loss. The goal is to help you get ready for upcoming races, improve your technique, and increase your fitness.

The program is coached and designed by CrossFit TNT’s head coach, Oscar Isacsson. Oscar has an undergraduate degree in Exercise Science and a Masters degree in Human Performance.
