Chris and I began by building my training volume slowly to ensure against injury, no small possibility given my body’s previous dormant decades. At first, it was around ten hours a week. A couple one-hour swims. Two or three Z2 runs of only an hour to ninety minutes maximum. A longer bike ride on Saturday morning, anywhere from three to four steady hours. And a longer run on Sunday, generally about 90 to 110 minutes in length.
