The aQuellé Midmar Mile is 1.6 km, held in Midmar Dam, KwaZulu-Natal. Most athletes need about 11 weeks of structured training for it. The block below is a real 11-week plan generated for a club athlete running about 40 km a week, 10 km in 50:00, building to 0 km in the peak week with volume rising no more than 10% a week and every fourth week coming down.

A 11-week block
Generated by the same engine that builds your plan, for a club athlete running about 40 km a week, 10 km in 50:00. Nothing here is illustrative — it is the actual output, and the rules that shaped it are published.

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 running about 40 km a week, 10 km in 50:00, the bands come out as:
| Pace band | Per kilometre |
|---|---|
| Easy — the ceiling, not the target | 6:07 |
| Marathon pace | 5:30 |
| Threshold | 5:11 |
| Interval (VO₂max) | 4:41 |
Computed from VDOT 40.0, 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
The tests you are missing are in week 2 of the plan rather than left as a suggestion, because a suggestion does not get done. The two times give your critical swim speed, which is what every pace in the swim sets is built from. One session, about half an hour.
Common questions
How long do I need to train for the Midmar Mile?
About 11 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 Midmar Mile specifically?
The largest open-water swim in the world. 1.6 km, at altitude.
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.
