I've been going stir crazy since breaking my left collarbone in three places on 23 June (17 days ago). I had surgery (two and a half hours' worth) on 29 June (11 days ago) to insert a titanium plate and screws. It's hard to explain the feeling of not getting aerobic exercise. Suffice it to say that, after 31 years of riding a bike and 16 of running, I'm miserable.
Though my doctor told me not to ride a bike for eight weeks, I went to the Maverick Activity Center with Katherine this afternoon. I rode a stationary bicycle (click the image to enlarge) for one hour, with no stopping and no let-up. I used my arms for support part of the time, but most of the time I sat up so as not to put any pressure on the collarbone. I got a terrific workout. My average heart rate was 135 and my maximum 155. To put this in perspective, the highest average heart rate I've ever seen while riding a bike is 132. The highest I've seen on my Garmin device is 128. The highest average heart rate I've seen while running is 148.
According to the stationary bike's computer, I burned 646 calories and pedaled 15.0 miles.
I feel alive again.
