Done in an Hour: Swim This is the start of a series that is intended for all of us who are constrained in the amount of time that we can devote to our training. The series title, "Done in an Hour…" formed the basis of the brief -- come up with a selection of workouts for the swim, bike and run that can be done in an hour, the sort of time we can squeeze in before work, as a long lunch or after work but before we have to deal with all the family stuff.

In this first of three articles, I look at three swim sessions that are designed to improve your technique, your race preparation, and your open-water swimming. All of these can be fitted into that magic hour as long as you focus on the task at hand.
