Avoid early race fatigue with this controlled speed workout. Start slower, then increase pace with each interval. This workout helps maintain control and avoid overexertion.

Begin with a warm-up of 10 to 15 minutes of easy jogging. Follow with form drills and strides. The workout consists of 3 x 2K intervals with three minutes of easy jogging between each. Read more culture coverage.

Run the first 2K slightly slower than your goal pace. The second 2K should match your goal pace. Finish the final 2K slightly faster. Keep the last interval hard but controlled, avoiding an all-out sprint. Related: Jonah Koech banned for three years for blood doping.
