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.
