Saturday Swim Session: 400’s For Success

Stamina developed by swimming 400s will be of benefit to all triathletes and open water swimmers. This session is perfect for Ironman and Olympic distance triathletes or people doing longer ocean swims.

Each Saturday I will post a Swim Session, most weeks I will load three options up for you to do. Option A is for swimmers who are after a workout between 1,000 & 2,000 metres. Option B is for swimmers who are after a workout between 2,000 & 3,000m and Option C will be greater than 3,000m.

I’ve written these sessions for a 33⅓ metre pool, but a lot of the older style pools are 33⅓ yards long (100 feet), so simply interchange the metres for yards and do the session.

Option A

  • 200m WU;
  • 4x 67m (33m Drill/33m Swim);
  • 3x 400m Build 1-3, 30sec RI;
  • 200m CD (1,867m)

Option B

  • 400m WU;
  • 6x 67m (33m Drill/33m Swim);
  • 4x 400m Build 1-4, 30sec RI;
  • 200m CD (2,600m)

Option C

  • 600m WU;
  • 6x 67m (33m Drill/33m Swim);
  • 6x 400m Build 1-3, 30sec RI;
  • 200m CD (3,600m)

Start the workout with a Warm Up (WU) covering 200m (Option A), 400m (Option B), or 600m (Option C). During the warm-up feel free to stop and stretch as needed.  It doesn’t need to be a continuous swim.

Next up is a drill set. There are four (Option A) or six (Options B and C) repetitions of 67m Drill/Swim, where you do a drill for the first 33m of the repetition and then normal swimming for the next 33m swimming. Feel free to use fins whilst doing the drill/swim set.  Do the drills below once through for Option A, if you are doing Option B or C go once through and then repeat the first two drills:

  1. Kick On Side (KOS) left side 
  2. Kick On Side (KOS) right side 
  3. 6/1/6 
  4. 6/3/6

I wrote an article about swimming drills previously. Click here to read and watch it.

Take the fins off prior to the next set.

The next set is made up of three (Option A), four (Option B), or six (Option C) reps of 400m. They all have a 30-second Rest Interval (RI) after each rep. This set is designed to be built as you work your way through it. For Option A, build each rep 1-3. Start off with a moderate-paced rep, then a faster rep, and then finish with your third rep being your fastest. For Option B which is built 1-4, do a similar process as with Option A. Start with a moderate rep, then a fast rep, a faster rep, and with your fourth rep make that your fastest rep. For Option C which like Option A is also built 1-3, work through the same process but then repeat it for reps 4-6.

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.
