Building up for a Half Marathon: Week 3

Week 3 has us bringing in some sustained tempo efforts to work on decreasing overall threshold running pace and increase your ability to hold a faster pace for a longer period of time for your half marathon.

  • Warm up 15 -30 minutes
  • Complete 3 x 2 mile tempo sets.
  • Warm up into the first 2 mile tempo. Tempos should be slightly faster than goal half
  • marathon race pace. Try to get faster for each 2 mile tempo
  • 5-10 minutes between each tempo set.
  • 10+ minute cool down
