This plan assumes that you have completed one of my Base modules and have established your endurance.

While the average training load is 11 hours per week, this plan is challenging because the key workouts are very specific to your needs as a Half Ironman athlete. Where appropriate, I have explained how experienced athletes can beef up the plan a bit.

Strength training is not emphasized but I have placed one strength session per week into the plan. This session falls on Monday in the first 6 weeks of the plan and Wednesday in the second 6 weeks of the plan. Within my own training I would use two session per week until the until the final two weeks of the plan. If you want to place a second strength session then the combo that fits best is Monday/Friday (first 6 weeks) and Wednesday/Sunday (next 4 weeks)

There is an important Half Ironman simulation workout that falls six weeks out from your goal race. You can substitute a B-, or C-, priority event for this race. An Olympic Distance race would be the most appropriate choice. If you are new to Half Ironman racing then, I believe, you will get the most benefit from following my race simulation workout that weekend.

The swimming program is focused on distance freestyle improvement with main set distance capped around 3000 meters (3300 yards). Where appropriate, I have explained how to dial the program up, or down.

The plan is appropriate for athletes racing all distances with weekly volume ranging from 8 to 13 hours per week.

Swim - up to 3,300 yards / 3,000 meters

Bike - up to 40 miles / 65 kilometers

Run - up to 10 miles / 16 kilometers


I hope you enjoy,

Sample workouts:

Workout #1 : Swim
PC 200s
Planned Time: 1:15:00
Pace Change 200s 16x50 all on 10s rest with this pattern • 3 Easy; 1 Fast • (4x) 1 Steady, 1 Fast • 3 Easy; 1 Fast +++ 5x200 Easy on 10s rest 4x200 Steady on 10s rest 3x200 Mod-hard on 10s rest 2x200 Fast on 10s rest 200 Max This swim can be shortened by dropping the 5x200 line. +++ Cool Down
Workout #2 : Strength
Strength Training, Base
Planned Time: 0:45:00
Please refer to Strength Training for Triathlon in the Strength section of the Endurance Corner Libarary (www.endurancecorner.com) and periodize your season according to the guidelines. If you are new to strength training then progress slowly.
Workout #3 : Bike
Aerobic Ride (60min)
Planned Time: 1:00:00
Choose one (or more) of the following and insert them into your ride: • 1-3 x 8 minutes at 92-94 cadence, take 2 minutes relaxed between if you are doing more than one interval • 5-10 x 1/1/1 minutes – 1 minute left leg, 1 minute right leg, 1 minute both legs • 3-10 x 3 minutes as 30 seconds super fast cadence (keep effort/HR moderate, make sure that your hips are stable and you are not rocking wildly!), 2:30 normal cadence • 2-5 x 5/5 minutes – 5 minutes at 92-94 rpm and 5 minutes at 65-70 rpm Single leg work only done indoors. Don’t one-leg-it down the road outside. Overall, aim for a steady effort – avoid your Mod-Hard zone.
Workout #4 : Run
Tempo Run (60 Min Main Set)
Planned Time: 1:20:00
Warm-up with 10 minutes easy running that builds to Steady Then do 6x 75 meter Strides with walking recoveries Main Set is 6 x 10 minutes Pattern is 2/4/3/1 • Steady • Mod-Hard • Steady • Walk Moderate your fast running so that you are able to recover while running Steady, not Easy Watch how your mind will tempt you to hammer once your heart rate rises Learn how to manage your pace effectively
Workout #5 : Swim
PC 50s
Planned Time: 1:00:00
Pace Change 50s 600 to 1,000 Easy building to Steady I like to mix the strokes a bit. Typically, I will swim at least every 4th length backstroke +++ 40x50 Main Set • 16x50 as 1 Fast, 3 Steady (x4); all on 5s rest • 12x50 as 1 Fast, 2 Steady (x4); all on 10s rest • 8x50 as 1 Fast, 1 Steady (x4); all on 15s rest • 4x50 as all Fast; all on 20s rest If you use paddles then you can put them one for the last 12 50s. Before that you should swim without gear. +++ Optional Additional Main Set 200 Easy; 4x200 Steady on 15s rest +++ Cool Down
Workout #6 : Run
Tempo Transition Run
Planned Time: 0:30:00
Run off the bike for 30 minutes repeating the following pattern (3x) 3 min Steady, 3 min Mod-hard, 3 min Steady, 1 min walk. NOTE: If you are decoupled (HR more than 7% over normal number for the pace) then you rode much more intensely than you realized. Adjust your bike effort downwards next time.
Workout #7 : Bike
Big Gear (5x8 Main Set)
Planned Time: 1:30:00
Warm Up with 10 minutes Easy cycling (10x) Alternate 30s Fast with 30s Easy 10 minutes Steady 5 minutes Easy (5x) 8 min Big Gear (65 to 75 rpm), Mod-hard effort on 2 min Recovery 5 min Easy NOTE: If you have extra time then you can extend this workout by placing 15-30 minutes of slightly easier then Steady effort/watts following the last Big Gear interval. POWER USERS: Mod-hard effort (with low cadence) should roughly equate to slightly UNDER FT power. I recommend that you stay under FTP for this session.
Workout #8 : Swim
Build Up Swim
Planned Time: 1:00:00
This entire swim is Easy to Steady effort on 10-15s rest 2x25, 100 2x25, 200 2x25, 300 2x25, 400 2x25, 500 2x25, 350 2x25, 250 2x25, 150 Focus on relaxed swimming with three-stroke breathing. Swim can be extended by inserting “2x25, 450” immediately after the 500.
Workout #9 : Bike
Aerobic Threshold (AeT) Benchmarking
Planned Time: 3:00:00
One of the most important data points to know is your pace/power at the bottom of your Steady zone (HR/Power/Pace). Whether you choose the benchmark HR, or Power, the goal of this workout is to do the majority of the ride sitting at the bottom of your Steady zone. If you have a powermeter then I recommend that you choose a flat ride and average the bottom of your Steady power zone. Watch your heart rate, review in 20 minute intervals. What you want to see is how stable your HR is over time. This is a good benchmark of the depth of your fitness. In my own training, I will build this workout up to four hours total duration. However, the four hour main set is a bit of a special occasion! More typical is 40-120 minutes of benchmarking. As you gain fitness you can make this main set progressive, moving through the bottom/middle/top of your Steady zone to see how you tolerate increases in training load. If you don't have access to power then you will need to focus primarily on the breath markers discussed in our training zone summary. All athletes, if you make a mistake then start too easy!
