Thomas Groden's 8-800's - Opt A

Swimming, December 08, 2025

This is a big, solid session that will build a solid base and develop the intrinsic ability to pace your longer swims. This session is great for swimmers and triathletes preparing for longer, open water swims.

For swimmers who are after a workout between 1,000 & 2,000 metres.

The inspiration for these sessions came from the former head coach of Boston College Swimming - Thomas Groden in an article by Olivier Poirier-Leroy read it here. The session has been adapted to fit the purpose of these articles, as it is 7,400yds total.

Option A

  • 200m WU;
  • 800m 1:30min RI;
  • 2x 400m 30sec RI;
  • 200m CD (2,000m)

Start the workout with a Warm Up (WU) by swimming 200m. During the warm-up feel free to stop and stretch as needed.  It doesn’t need to be a continuous swim.

The main sets are made up of sets that are 800m long. Start with a single 800m rep before taking a 90-second Rest Interval (RI).

The next set is made up of two, 400m reps. Take a 30-second Rest Interval (RI) between reps and then prior to the next set as well. If you are doing Option A, move to your Cool Down (CD) at this point.

The following set is made of four, 200m reps. Between these reps take a 15-second Rest Interval (RI) (as well as prior to the next set if you aren't moving to the Cool Down (CD)). If you are doing Option B, move to your Cool Down (CD) at this point.

The final set is made up of eight, 100m reps, with a ten-second Rest Interval (RI) between reps.

For the Cool Down (CD) swim 200m. Unlike the previous sets which have to be freestyle, the cooldown (like the warm-up) can be any stroke you wish to swim.  You can also stop and rest after any length.  I encourage you to stop and stretch during the cool-down.
