The Ironman African Championship is 3.8 km swim, 180 km bike, 42.2 km run, held in Gqeberha. Most athletes need about 24 weeks of structured training for it. The block below is a real 24-week plan generated for a club athlete on 45 km a week with a 1:55 half marathon behind them, building to 85 km in the peak week with volume rising no more than 10% a week and every fourth week coming down.

Load is Training Stress Score: hours × intensity factor² × 100. It is the unit that lets running, riding and swimming be added into one number, which is the only honest way to manage an athlete doing more than one sport.
The paces behind it
For a club athlete on 45 km a week with a 1:55 half marathon behind them, the bands come out as:
| Pace band | Per kilometre |
|---|---|
| Easy — the ceiling, not the target | 6:19 |
| Marathon pace | 5:41 |
| Threshold | 5:22 |
| Interval (VO₂max) | 4:51 |
Computed from VDOT 38.3, derived from that time trial using Jack Daniels' model. Your own numbers will differ — the plan builds these from a time trial you enter.
What this plan says out loud
Your race is 25 weeks away. This plan covers the last 24 weeks, which is as far ahead as a specific plan is worth writing. Keep training as you are until then.
Worth saying plainly about swimming: for most amateur swimmers, improvement comes from technique rather than fitness. This plan can prescribe the work. It cannot see that your hips are sinking or your catch is dropping, and no amount of threshold sets fixes a stroke. If you can afford one thing, buy a few sessions with a coach on the pool deck rather than more sets from us.
Some sessions have been cut to fit the time you said you have — 75 minutes on a weekday and 210 at the weekend. That is a real constraint and the plan respects it, but be aware the long session is the one that matters most: if you can find more time anywhere, find it on the weekend.
On 6 days a week there is nowhere to put 34 km without prescribing runs nobody should be doing. The plan caps individual easy runs at 14 km and carries less volume than your target as a result. More days would do more for you than longer runs.
Common questions
How long do I need to train for the Ironman South Africa?
About 24 weeks from a reasonable base. Less than that is possible but the plan stops being about building fitness and starts being about arriving intact — six weeks before a long race, no meaningful aerobic fitness can be added, and any plan that claims otherwise is selling you something.
How much should the weekly volume go up?
No more than 10% a week, and every fourth week comes down to about two thirds. That ceiling is the single most useful injury-prevention rule in endurance training, and it is enforced here rather than suggested.
Do I need a time trial first?
Yes, to get paces. Without a recent race or time trial the plan will not invent them — it prescribes by effort instead and says so. Guessed paces are how people train the wrong intensity for months.
What should I know about the Ironman South Africa specifically?
3.8 km swim, 180 km bike, 42.2 km run. Expect wind on the bike — it is the defining feature of this course.
What does it cost?
Building a plan is free and the first week is unlocked to train on. The whole block is paid for once, from R150, priced by how long it runs. There is no subscription.
