Santa Maria Waterfall Steady-State Walk, Costa Rica

I really enjoyed this challenging steady state workout. But this is one of the workouts that when it’s finished the cool down is at .5 miles an hour or half a mile an hour and I almost fell off my treadmill because it stops and then versus forward a little bit. This treadmill does not function below 1 mph.
I did experience a little pain in my right knee about halfway through the workout as my leg would raise. But the pain only lasted for about five minutes.
Technology issues: none.
