STRUCTURING YOUR 70.3 TRAINING

Preparing for a 70.3 requires more than simply training hard, it’s about structuring your week so that the right sessions are layered together to develop threshold, aerobic durability, race-pace efficiency and technical skill, while still allowing enough recovery to absorb the work. A well-balanced programme blends swim, bike and run intensity across the week to target VO₂ max, lactate threshold and economy, supported by strength and conditioning to improve resilience and reduce injury risk. By distributing harder sessions earlier in the week and allowing space for recovery before your key weekend endurance work, you can arrive at your long race-specific sessions in a state where quality remains high.

Below is an example of how a typical training week within a 70.3 programme may be structured:

Day 

Session 1 

Session 2 

Monday 

2–3k Threshold Swim 

50min Threshold Run 

Tuesday 

Strength & Conditioning (Plyometrics / BW) 

60min Tempo Bike 

Wednesday 

2–2.5k VO₂ Swim 

Run Threshold 400s (Track) 

Thursday 

50min VO₂ Bike 

Easy Technique & Aerobic Swim 

Friday 

Stretching / Mobility 

Optional Recovery Bike 

Saturday 

90min Aerobic Easy Run

 Resistance Strength Session 

Sunday 

2.5hr Bike (70.3 Race Pace Reps) 

15min Brick Run (Build to RP → Hold → Ease Off) 

Structuring your 70.3 training in this way ensures you’re developing the physiological and technical demands required for race day success.
