Chicago Marathon “Booster”


Run the race of your life and increase your endurance power by up to 35%!

6 Weeks

Suggested start date: August 6

This program is flexible and is able to be completed on your own time. It includes a consultation with a Well-Fit coach, baseline test, 9 altitude sessions (2x per week) and a final test. The plan can be incorporated into any existing training plan and will be delivered through Training Peaks. We suggest a start date of the week of August 6 to get the maximum benefit.

“Since 1968, after the Mexico City Olympics, 95% of all Olympic and World Championship medals from the 800 through the Marathon were won by the athletes who lived or trained at altitude”- Dr. Joe Vigil 2008 USA Olympic Team Running Coach

The Well-Fit Altitude Booster program is based on the groundbreaking research of Dufour et all in 2006 that was published in the Journal of Applied Physiology.

Simulated altitude, not actual altitude

In real altitude the atmospheric pressure is decreased and the air molecules are further apart making the air thinner. The percentage of oxygen in the air is the same as at sea level but there is just less air. If you need more oxygen you need to get it from a tank or wait for a few hours. In simulated altitude there is no change in atmospheric pressure and to achieve the same effect, the oxygen molecules are filtered out. The air stays at the same density but with lower percentage. If you need more oxygen you just open the door and leave the room and you are in normal oxygen conditions.

Why does it work?

The mechanism by which altitude training works is very simple – since oxygen is the primary source of energy production for the human cell, it is the key limiting factor to success and athletic ability.  Exposure to altitude or reduced oxygen levels introduces a new challenge that the body must confront and adapt to maintain balance. This balance is your new level of fitness.

There are two major altitude models that are used by athletes and everyday people:

  • Live High – Train High: Maximum exposure to altitude and maximum increased oxygen delivery from the lungs to the muscles achieved by increasing the amount of red blood cells. However, this method has somewhat limited performance at sea level, mostly due to inability to train at high intensity.
  • Live low – Train High: Maximizing oxygen absorption and processing in the working muscles when using high-intensity training protocols in order to improve performance for endurance athletes at sea level.  Mostly achieved by increasing the cells ability to absorb and process oxygen.

How does the program work?

As a runner training for a race, you should have three kinds of workouts in your training plan; speed, tempo and endurance. During the altitude booster program, we will replace your speed and tempo sessions with altitude workouts. The endurance workouts will come from your current program. Our coaches will work with each individual athlete to adjust his/her training plan to fit with this program.
