About 20 minutes from downtown Denver is the famed Red Rock Amphitheatre. An acoustic marvel set among magnificent red rock formations, it’s a great place to view the mile high city. We felt the altitude immediately when climbing the 69 steps to the view from the top. There were dozens of very different athletes performing all kinds of workouts. We saw some runners methodically covering the entire arena row by row, others frog hopping up the steps and fitness teams performing crunches and reverse incline pushups straddling multiple rows. Here’s a workout for any ambitious reader - http://www.active.com/fitness/articles/take-your-endurance-training-to-the-stairs. Just walking the steps felt like an accomplishment and the views were worth the effort.
