Bike and Run

Today was a double workout since I didn't do the ride yesterday. In the morning, I got up and rode 1.5 hours on the CompuTrainer at between 150 and 200 watts. The object of this workout was simply to ride at a fairly constant power at about 20 beats below lactate threshold heart rate (LTHR). I notice that my power started to drop off about halfway through the workout. I started at a load of 200 watts, but at about 45 minutes in, my heart rate started to rise higher than 20 bpm below LTHR, so I scaled back. Unfortunately, the CompuTrainer's ergometer function steps the wattage by 50 watts, so when I scaled back to 150 W, my HR dropped to almost 30 bpm below LTHR. So, I ended up alternating between 150 and 200 watts for the remainder of the ride, hence the large peaks and valleys that appear on the power graph (pink) at the left.

After we went to a Christmas party, I took the boys for a run in the new jogging stroller. It is a pretty sweet ride for them. It's a Chariot Cougar 2 with the jogging stroller option. Rides fairly smoothly and is easy to push. It does pull to the left a bit. Gotta figure that one out. Anyway, I'm sure I ran slower than I would have without the boys, but I got the HR up into the upper aerobic zone. I think I ran about 4.75 miles or so. Good training day.
