About this workout

This session links three long threshold repeats with floats instead of jogs. You run 3 km at threshold, float 1 km at marathon pace and continue straight into the next 3 km. After the third repeat the session is complete, so you cover eleven kilometers without a break.

The floats keep the effort continuous and the heart rate high, while the lower pace lets you clear some fatigue. Over eleven kilometers this builds strong threshold endurance and the ability to recover at a steady pace, which suits half marathon and marathon preparation. Hold back on the first repeat, because the float pace adds up.

It is for experienced runners with 60 km or more per week. Use it every two to three weeks in the build phase. A lighter version uses two repeats with one float.

Tips

  • Keep the floats at marathon pace rather than jogging.
  • Drink during a float if it is warm.
  • Use a measured road or loop so the changes come at the right point.
