Phil Mosley


I have 20 years experience of helping amateur athletes surpass their goals, while still making sure they have quality time available for family, friends and career. As a parent who works for a living, I know how challenging this can be.

My training plans are intelligently designed around a typical work week. I set proven, time-efficient workouts in mid-week, with longer aerobic workouts at the weekends. This gives you the structure and consistency you need to continually improve.

Sample Day 1

Fitness Test: FTP and Threshold HR

This fitness test helps you to set your power or heart rate thresholds for Training Peaks.

Warm Up:
12 mins in Z2,
5 x (15 secs in Z4 + 45 secs easy in Z2).

Main Set:
20 mins maximal steady state time trial. Go as hard as you can sustain for 20-minutes.

Warm Down:
5 mins in Z2.

Note: Alternatively, if you have a bike training device with its own "FTP" test protocol, you could use that instead.

TIP: Have a fan and/or air conditioning, so that heat stress is not a limiting factor for this test.

Sample Day 2

Fitness Test: Critical Swim Speed (CSS)

This test will determine your Critical Swim Speed. Enter this in your TrainingPeaks settings (see below) to see the planned distance and duration for all swim workouts.

Warm Up:
6 x (50 FS in Z2 + 20 sec rests),
4 x (25 FS in Z4 + 25 FS in Z2 + 20 sec rests).

Main Set:
1 x 400 FS maximal effort time trial, record time,
5 mins easy active recovery,
1 x 200 FS maximal effort time trial, record time,
1 min rest.

Warm Down:
400 Choice in Z2

For all swims (whether in a Yard or Meter Pool) follow the distances in the Workout Description section. There is also yard/meter button you can toggle in the Workout Details section below.

Sample Day 4

Fitness Test: Threshold Pace and HR

This fitness test helps you to set your pace and heart rate training zones and thresholds for Training Peaks. 

Warm Up: 
5 mins in Z2 (easy/steady),
4 x (30 secs accelerating from Z2 to Z4 + 30 secs recoveries in Z1).

Main Set: 
Run for 30 mins at the fastest pace you can maintain for the duration. Record your average pace and ideally average heart rate too. 

Warm Down:
5 mins in Z1 to Z2 (easy).

Sample Day 5

Pool Swim: Threshold Efforts

These workouts involve a main set of efforts at threshold pace. They will boost your pace and increase your ability to hold race pace for longer.

Warm Up:
1 x (100 FS in Z2 + 100 Pull in Z2 + 15 secs
1 x (50 FS in Z2 + 50 FS in Z3 + 20 secs rest),
1 x (50 Pull in Z2 + 50 Pull in Z4 + 20 secs rest).

Main Set:
1 x (400 FS in Z4 + 40 secs rest),
1 x (300 Pull in Z4 + 40 secs rest),
1 x (200 FS in Z4 + 40 secs rest),
2 x (100 Pull in Z4 + 40 sec rests).
