The First Combined Pool and Open Water Coach Course: Bali and the Gap World Aquatics Just Acknowledged

On the fifth day of the course, eighteen coaches from twelve countries walked into the open water off Bali. No lanes, no pool wall, no starting horn. They practised pack swimming, drafting the swimmer ahead, taking feeding from a boat, and the feel of a beach start. In a pool, almost none of them had ever taught these skills. That is the entire reason the course exists.

From August 3 to August 10, World Aquatics ran the first international youth coach course to combine pool swimming and open water swimming. The notable point is not that another class appeared on the calendar. It is that the global governing body of swimming has acknowledged that the two halves of the same sport have been split apart for too long at the most important stage: the training of the people who teach.

To understand why this is worth writing about, look at the certification architecture World Aquatics is building. The system has three tiers: Age Group Coach, Youth Coach and Performance Coach. The Bali course sits in the middle tier — Youth Coach — the tier that serves young athletes, where technical foundations and training habits take shape. Delivery follows a blended model: online learning through the CORAL platform, then hands-on practice. This is a deliberate approach to lower marginal cost when expanding to developing federations.

Eighteen participants, seventeen of them on scholarships. That figure matters more than it appears. A scholarship is an access instrument: it signals that World Aquatics wants to widen the base of certified coaches beyond wealthy federations, rather than serving only places that already have infrastructure.

The specialist content was led by Mel Tantrum, head coach of Australia's Paralympic swimming programme and lead developer of World Aquatics' open water coaching certification courses. That overlap of two roles is worth noting. It shows the certification content is designed with an awareness of transferring knowledge from the elite level down to the grassroots, and it may carry the inclusive coaching principles of the Paralympic pathway with it.

The content structure follows a loop of theory then application. Classroom topics include athlete-centred coaching, long-term athlete development, season planning, session design, communication and building positive learning environments. Practical work takes place in the water, focused on the skills specific to open water. This is mainstream pedagogy, not a new technical method. The value lies in applying it to a group that has never been fully served.

One thing the original release does not say needs to be stated plainly: the professional focus of the course is coaching methodology and how to deliver open water skills, rather than refining the technique of any individual athlete. There are no split data, no stroke rate, no distance per stroke, no underwater time. Any technical statement here is pedagogical and descriptive only. The technical content that genuinely transfers falls into four groups: pack swimming, drafting, feeding and starts. These are skills the pool does not teach, and they are exactly where most pool coaches are least confident.

The bottleneck in grassroots open water lies with the teacher: there are too few coaches confident and skilled enough to take athletes into the sea. A strong pool coach can teach flawless technique in a lane, but taking an athlete to the sea forces them to handle a new set of variables: currents, temperature, waves, the gaps between competitors, drafting tactics, and above all safety. The Bali course places safety and risk management among its highlight topics, and that is no accident.

From a governance angle, an open water certification course is first and foremost an upstream quality-control tool. As federations increasingly require open water certification as a condition for sanctioning events, coach training becomes a soft governance lever. It shapes safety, ethics and athlete-welfare standards without regulatory force. This is the kind of change that draws little attention but carries long-term reach.

Data does not judge, but it points me to the questions others forget. Looking at the tiered certification architecture with the CORAL online platform attached, the first thing I asked myself was not how good the course was, but whether it can scale. A blended online-and-in-person model has low marginal cost. If it works, World Aquatics can reach coaches in federations that have never had the means to send anyone to train. The most important systemic point here is distribution, not depth.

I once misread a player's name at a World Cup, and from that I rebuilt the whole way I watch a match. I tell this story not to talk about myself, but to talk about the logic behind a course like the one in Bali. After my mistake in 2026, I realised perfection has to come from a system, not from memory. An open water coach is the same. You cannot rely on instinct in front of the sea. You need a framework: position, responsibility, weakness, and a risk process written down before entering the water.

Some findings do not come from luck, but from being willing to read the movements the crowd overlooks. Here, the movement worth reading is that the course merges two things that have been kept apart. Pool swimming and open water share a common physical and technical base, but differ in tactics and risk management. Merging them into one training programme reflects a market reality: the Olympic 10km marathon swim and age-group open water events are growing, creating demand for coaches who can bridge both environments.

Seen on the global development map, Australia's technical influence in open water shows clearly through Tantrum's role. One country acts as the technical expert, while the governing body sets the standard and distributes it. A cohort of twelve nationalities and seventeen scholarships points to a strategy of widening the coaching base beyond traditional powers. The message that "no single country or system has all the answers" is a diplomatic signal: World Aquatics is deliberately decentralising open water expertise rather than anchoring it in one place.

Here we must pause on the most-cited figure: 94% of eighteen evaluation responses said the course exceeded expectations. That sounds very good. But it is a satisfaction survey, not a measure of training effectiveness. The sample is only eighteen people, self-selected, mostly on scholarships — three factors that together tend to push positive sentiment above reality. Scholarships remove the cost barrier, a common source of dissatisfaction, so the satisfaction score is hard to keep from being inflated.

More importantly, the true measure of a coach-training course is not how learners feel right after it, but what happens in their programmes two to eight years later. The programme's own material acknowledges that the ultimate measure is what coaches take back to their athletes and clubs. But the release provides no data at that level. So the claim that the course raises global coaching standards remains unverified.

There is a constructive signal in the feedback. Participants asked for more open water practicals, more race simulations and more real-life coaching scenarios. This shows the practical component was valued but under-supplied relative to demand. For a first-run course, this is a common finding: theory takes a larger share than learners' appetite. This is the most valuable kind of feedback data, because it points straight at what to adjust next time.

An injury is where every analytical model must bow, and also where I have learned the most. In open water, the analogous variable is not injury but environmental risk. A course that teaches safety and risk management admits that the sea cannot be fully controlled. That is why training open water coaches is vital: a certified coach can be the difference between a safe open water event and an incident.

Looking at the industry ripple chain, the main impact is upstream: raising the number and quality of certified coaches improves the input into athlete development, with effects appearing years later. In the middle, coaches and their programmes are the transmission channel. Downstream, age-group open water events and mass-participation movements benefit indirectly, because better safety opens the door to more events.

On finance and equity, there are two systemic risks. First, seventeen scholarships create a dependency on the governing body's budget. Second, relying only on in-person courses caps reach at those who can attend or be funded. The lever to overcome this limit is the online learning platform, which lowers the marginal cost of reaching coaches in developing federations.

It is worth remembering that the news hook of the event lies in the word "first". Remove it, and this is just a routine programme update. A first-run combined format usually faces a go-or-no-go decision: to scale or not. And that satisfaction survey is, in the end, the evidence for making that decision.

For a first-run course, the question is no longer whether it was good or bad. The question is whether this combined format will be repeated and expanded, and whether it will be judged by outcomes rather than by satisfaction forms. If World Aquatics can track what coaches take back to their athletes, this may become one of the highest-leverage investments in the sport. If not, it will remain just a fine week in Bali.
