Sample Day 1

Functional Threshold Power/Heart Rate

This is done on an indoor trainer using a powermeter. If you are using Heart Rate (HR) then still do this test, and use average HR data.

Warm up 20 minutes at easy to endurance pace.
3 x 1 minutes with 1 minute recovery with high cadence around 100rpm.
5 minute easy riding

Main set start with a 5 minute all out effort.
10 minutes easy riding
20 minutes time trial - this is the section you will use to determine your FTP
If using HR rather than power meter then do 25 minutes

Cool down 10 minutes to 15 minutes easy cycling.

Power Data
Once you have downloaded your data you need to determine your average power for the 20 minute interval. Take your average power and multiple by 0.95 to calculate your FTP. So if your average power is 305watts x 0.95 = 290w is your Functional Threshold Power.

Heart Rate
If using Heart Rate then take your average heart rate from the final 20 minutes of the 25 minute interval. Multiple this number by 0.95 to calculate your Lactate Threshold.

This training plan is based on 6 Training Zones for Power and 7 Training Zones for Heart Rate which can be found in Training Peaks.

Heart Rate training zones are based on Lactate Threshold - Joel Friel for Cycling.

Power is based on Threshold Power - Andy Coggan (6).

Use your FTP and/or Lactate Threshold HR and put in the Zones within Setting in Training Peaks to calculate your relevant Zones which will be used for future work outs.

Sample Day 2


20 min Very Easy Run

Sample Day 3

Swim Threshold Pace Test Set

This swim is designed to determine your Threshold Swim Pace (T-Pace). This will be used in a number of swims sessions.

Warm up: 200m building speed each 50m (slow-medium-faster-fastest).

Rest 30 sec.

Then 5 x 400m (10 sec recoveries) building speed on each 100m (slow-medium-faster-fastest).
Recover 10 seconds after last one.

Then swim a 500m time trial. All out.
Your average 100 pace for this is your T-Pace for future workouts.

Then swim easy, 100m cool down.

Sample Day 5

Lactate Threshold Test for Running

This test is designed to determine your Lactate Threshold Heart Rate and Pace.

Warm Up for 15 minutes.
In this WU include some bum flicks, high knees, walking lunges and 4 x 20 second accelerations (try to run each acceleration faster than the previous - not a flat out sprint, but getting Heart Rate up, 40 seconds recovery between reps).
Want to be very warmed up ahead of Main Set

Main Set:
Run a 30 minute time trial on flat course/track. Punch HR monitor 'lap' button 10 minutes into Time Trial. Average heart rate for last 20 minutes predicts Lactate threshold heart rate (LTHR).

Cool Down:
Easy run to make time up to 1 hour. Walk last few minutes.

Sample Day 6

1hr Ride in Zones 1 - 2 (easy pace)

1hr Ride in Zones 1 - 2 (easy pace)

The IronMan UK Bike Course in 2019 had around 15m of climbing for every km (so around 2600m over the 180km).
Therefore, try to ensure you are achieving this in your long rides.
If a 2.5hr ride covers 50km aim to gain 750m of climbing (50km x 15m = 750m of climbing).

This will get you used to climbing this ascent.

Sample Day 7

40 Minutes Easy Run in HR Zones 1 - 2

40 Minutes Easy Run in HR Zones 1 - 2

The IronMan UK Run Course is a loop with a total elevation gain of just over 300m. Try to ensure on your long runs you achieve 7m to 8m of ascent per km
If you cover 10km in a 1hr run, try to ensure you climb 70m - 80m as a minimum. Although not a lot of climbing it is good to get used to the rolling nature of the climb.

HR Zone should be in Zone 1 - 2 for majority of this run (it may go in to Zone 3 - 4 for uphills by try to keep in Zones 1 and 2).

Sample Day 8
