I work out at Lifetime Fitness on Mayo Blvd. in North Scottsdale. They just installed new treadmills and it was my first time running on them. They have fancy TV monitors, an iPhone / USB jack, a speaker port and a workout track graphic. Unfortunately, I had a lousy 40-minute workout today. Maybe I am fatigued from the travels or maybe it’s the new treadmills. It is taper week for me as I am doing the half-ironman relay (run) on Sunday. I just ran 40 minutes.
