This session is great to improve speed for runners over 5km. It is perfect for both runners and triathletes alike.
Each week I will be posting the Friday Fartlek Run Sessions that you can do to enhance your running. Fartlek is a Swedish term that runners often use and it means speed-play. See a previous post about training intensity (levels) to know how hard to work.
The inspiration for this session comes from an article on Training Peaks written by Rick Kattoff from TeamKattoff Coaching. Read the original article here.
Rick Kattoff’s 40/20 Workouts
- 10min WU Level II;
- 6-10x 40sec Level V, 20sec Level IV RI;
- 10min CD Level II;
- 10min Stretching
The Warm Up (WU) should be done at an intensity that is steady, but not overconsuming at Level II for ten minutes.
The main set is made up of a number of reps of 40 seconds duration at your Level V pace (your goal 5km pace), then run for 20 seconds duration at your Level IV pace (0:19/km or 0:30/mile slower than goal pace) for a slight Rest Interval (RI). Complete a mile of this 40/20 running before moving to the Cool Down (CD).
The Cool Down (CD) is at a low intensity, jogging (Level II) for a minimum of ten minutes.
Finish with 10 minutes of stretching to assist with the recovery.
Check the table below to see the pace you should be aiming to achieve based on your 5km Goal Time.
|5km Goal Time||0:18:00||0:20:00||0:22:00||0:24:00||0:26:00||0:28:00||0:30:00||0:32:00|
|20 sec RI||0:03:55||0:04:19||0:04:43||0:05:07||0:05:31||0:05:55||0:06:19||0:06:43|
|20 sec RI||0:06:18||0:06:56||0:07:35||0:08:13||0:08:52||0:09:31||0:10:09||0:10:48|
Each week aim to increase the distance you run. When doing the 40/20 running session, progress each week a little, maintaining your pace building towards 3-4 miles of running at this effort.
