Cruise Intervals

The Cruise Interval workout was popularized by the running coach, Jack Daniels. They, like the other Stamina workouts, are meant to increase your lactate threshold pace. Cruise Intervals are like shorter and slightly more intense tempo intervals. They last three to eight minutes and the pace is between 8K and 12K. Like tempo intervals, they are followed by short recovery jogs (30 seconds to 2 minutes). You'll probably find that it's easy to run too fast on these. The tendency is to treat them like regular long intervals. However, keep it under control and work on a smooth, fast rhythm. Control in training is key to improvement.
