Midmar Mile 2027 training plan

What the Mile asks of you

For most swimmers the mile takes somewhere between 25 and 50 minutes. Fitness for that is very achievable in three months. What catches people out is the water itself:

• No black line and no walls. You can't push off every 25 m to rest, and you have to keep yourself straight.
• A crowded start. Swimmers start in batches, and the first few hundred metres are busy with arms and feet.
• Sighting. You have to lift your eyes to find the buoys, which costs a little speed and a lot of rhythm if you haven't practised it.
• Chop and cold. Wind on the dam, other swimmers' wash and cooler water than a heated pool all make it feel harder than the same distance indoors.

The training phases

From early November there are about fourteen weeks to the race. That is a good runway if you can already swim a few hundred metres without stopping.

A typical week

This is the shape of a week in January, not a prescription. Scale the distances to where you are.

If you are starting from scratch

First get to 400 m of continuous swimming, at any pace and with any stroke. A few lessons on breathing and body position save more time than any amount of hard sets. Once 400 m feels comfortable, follow the phases above and add distance gradually.

Open-water skills

• Sighting. Lift just your eyes forward, then turn to breathe. Pick a big landmark behind the buoy, not just the buoy itself.
• Breathe to both sides. If the wind or the sun is on one side, you can breathe away from it and still swim straight.
• Draft. Swimming just behind someone's feet or beside their hip saves energy. Practise it in your group swims.
• Start sensibly. If you are nervous, start at the side or the back of your batch and let the fast swimmers go.
• Never swim open water alone. Join a club or group session, and wear a bright cap.

Seeding and the events

The organiser seeds swimmers into starting batches once online entries close. Late entries on race weekend go into one of the last two batches. The remaining 2026/7 seeding events are:

A seeding swim is also the best open-water rehearsal you can get. On race weekend, the team events and Event 1 are on Saturday 13 February, and the individual age-group events are on Sunday 14 February. Every member of a team swims the full mile, and the team result uses its three fastest times. Check midmarmile.com for your event, start time and entry details.

Race day

• Eat a normal breakfast two to three hours before your start. A mile doesn't need fuel during the swim.
• Warm up if you can, even with a few minutes of arm swings and easy jogging on the bank.
• Swim the first 200 m firmly but not flat out, then settle into the rhythm you trained.
• Sight more often near the turns and the finish, where it is easiest to drift.

Midmar for triathletes and biathletes

The Mile is excellent open-water practice for a triathlon. Event 1 also includes the Comrades and Dusi biathlon and Ironman/Ironwoman categories, which combine your Midmar result with your Comrades and Dusi results. Entering those needs your 2026 Comrades or Dusi race number and official results, and they take pre-entry only, with no late entries on race weekend. If the 100th Comrades is on your list too, the swim makes good cross-training early in the build.

How SportMentor builds your Midmar plan

Tell your mentor you are swimming the Midmar Mile, how often you can get to a pool and to open water, and what you want from the day. It builds a week-by-week plan to 14 February from your own training, whether that comes from Garmin, COROS, Polar, Suunto, Intervals.icu, Strava or Fitbit, or from sessions you log yourself.

• Your swim pace per 100 m from synced swims shapes the sessions, so the sets fit the swimmer you are now.
• Missed a week or swapped a pool session for the dam? The plan adjusts the weeks ahead.
• Guided strength sessions for shoulders, back and core fit around your swims and your kit.

Questions swimmers ask

How long does it take to swim the Midmar Mile?

It depends on your pace in open water. At 2:00 per 100 m the mile takes about 32 minutes, and at 2:30 per 100 m about 40 minutes. Expect to be a little slower than in the pool, because there are no walls to push off and you have to look up to sight.

Can a beginner swim the Midmar Mile?

Yes, if you can already swim continuously and give yourself time to build. Aim to swim 1,600 m in the pool without stopping at least four weeks before the race, and do several open-water swims with other people before race day.

How does seeding work?

The organiser seeds swimmers into starting batches once online entries close. Late entries on race weekend go into one of the last two batches. Swimming one of the official seeding events gives you a time to work from. Questions go to seeding@midmarmile.com.

How many times a week should I swim?

Three sessions a week is a good target: one endurance set, one faster set and one open-water or technique session. Two sessions a week can get you round, but three make the last kilometre much more comfortable.

Do I need to fuel during the Midmar Mile?

No. A mile is short enough to swim on a normal breakfast eaten two to three hours before your start. Drink normally beforehand and have something to eat and drink waiting at the finish.
