Active at Altitude is a residential  retreat center for running vacations, active vacations, and training at altitude. We provide a welcoming, comfortable and relaxing base for athletes of all abilities that supports a wide range of physical activities in an ideal location at altitude. We work on the principle that if you are active you are an athlete!

The centre is located in Colorado, USA, between the highly popular areas of Boulder and Estes Park. We are based at 8,200 feet above sea level, providing an opportunity to live high and train lower that research has suggested is the best way to maximise the benefits of training at altitude. These benefits can be enjoyed by everyone of any ability.  We are situated close to Rocky Mountain National Park, one of the most beautiful and awe inspiring places in the world.
