How AI has greatly enhanced  the way I coach age group County, Regional and National swimmers

If you’d asked me a few years ago what coaching swimming looked like, I’d have said: stopwatch, laptop, whiteboard, instinct, and experience. That was the craft. And it still is, at its core.

But now?  AI has fundamentally reshaped how I coach, not by replacing me, but by amplifying everything I do. It's like having the most eager, brilliant and insightful assistant coach at my side. 

From Seasonal Guesswork to Precision Planning

One of the biggest shifts has been in annual and macro planning.

I now map out the season with far greater clarity, aligning training blocks to competition demands, physiological development, and athlete readiness. Using structured calendars and planning tools, I can see exactly how a swimmer progresses from 

September aerobic work to a championship taper.

That long-term structure used to live partly in my head. Now it’s explicit, dynamic, and constantly refined with eqse. I can connect a Tuesday night session in October directly to a race in May—and justify every metre in between.

Even something as detailed as training zones is no longer just theoretical knowledge. I actively apply models of aerobic capacity, threshold, and lactate tolerance to ensure sessions hit the intended physiological targets. And I do this with charts using 

Designing Better Sessions, Faster

Session planning has become sharper and more purposeful.

Take a typical P2 session: I’m designing sets that deliberately target A2 aerobic development, pacing discipline, and skills under fatigue—not just “a hard set,” but a clearly defined outcome.

AI helps me:

  • Generate variations of sets aligned to specific energy systems

  • Check progression across a week or cycle

  • Balance volume, intensity, and skill focus

What used to take hours of manual thought, I can now iterate quickly—and more importantly, improve. I’m not starting from scratch each time; I’m refining a system.

Individualisation at a Completely New Level

Where technology has really transformed my coaching is in individual athlete work.

I can now build detailed profiles of swimmers that go far beyond times. Using structured frameworks like the Person → Athlete → Performer model, I’m looking at:

  • Behaviour and mindset

  • Physical and technical development

  • Race execution under pressure 

For example, when analysing a swimmer who is a National Qualifier, I’m not just noting that they have strong IM and butterfly. I’m identifying:

  • Aerobic gaps in distance freestyle

  • Opportunities to convert near-miss qualifying times

  • Behavioural patterns like consistency and training habits 

AI helps me synthesise all of that into clear, actionable priorities.

It’s like having an assistant coach who can process everything instantly—yet the decisions remain mine.

Solving Problems More Effectively

Coaching is constant problem-solving.

Why is a swimmer plateauing?

Why are they dropping stroke length under fatigue?

Why are they missing race execution?

Previously, those answers relied solely on experience and reflection. Now, I can interrogate those problems more deeply:

  • Compare training data against expected adaptations

  • Generate hypotheses quickly

  • Explore alternative approaches

Even reflections—like when a session doesn’t quite land—become more useful. I can analyse what happened, adjust communication, or redesign sets with more clarity.

Race Planning and Performance Detail

Race planning has also evolved massively.

Instead of vague instructions like “go out strong” or “build the back end,” I now create detailed race models:

  • Split targets

  • Stroke-specific cues

  • Tactical intentions

For a swimmer, that might look like:

  • Controlled fly → build back → precision breast → aggressive free

  • Exact split expectations across each 50

This level of detail transforms how swimmers understand performance—and how consistently they can execute it.

Supporting Younger Swimmers More Effectively

Technology hasn’t just helped with top swimmers—it’s arguably even more impactful with younger athletes.

For 10–12-year-olds, I can design structured progression plans where:

  • Every session has a clear objective

  • Skills are reinforced consistently

  • Confidence is deliberately built

For example, an 18-session gala preparation plan ensures that every swimmer understands starts, turns, and race skills—not just fitness.

That level of consistency is hard to maintain without support. AI helps me stay disciplined in my own coaching.

Becoming a Better Learner Myself

Perhaps the most important change is how technology has affected me as a coach.

I’m no longer limited to what I already know.

Alongside formal learning through the Institute of Swimming, I’m constantly:

  • Exploring new coaching ideas

  • Testing different physiological models

  • Reflecting on my own behaviours and decisions

The expectation now is continuous development. The Optimal Coach Development Framework reinforces that coaches must be students of the sport, always evolving and refining.

AI accelerates that process. It challenges my thinking, fills gaps, and sharpens my approach.

The Balance: Technology + Coaching Instinct

Despite all this, one thing hasn’t changed.

Coaching is still about people.

It’s about:

  • Reading a swimmer on the poolside

  • Knowing when to push and when to hold back

  • Building trust and belief

Technology doesn’t replace that. It enhances it.

The best way I can describe it is this:

AI gives me better questions, better structures, and better options. I learn on the fly; just in time, at the point of need. 

But the coaching—the judgement, the relationships, the environment—that’s still human.

And always will be.

Day One Summary – Senior Club Coach Training (Loughborough)

Visible to anyone in the world

Fifteen years ago, I gave up my fledgling swim coaching career to join the OU.

I was in the process of completing my Senior Coach Accreditation, with courses in Nottingham, Manchester and London. The OU called, stating that I am working at the business school and need to complete an MA in Open and Distance Education. I learnt a great deal from the course. I learnt how to learn. I know how to apply creative thinking. And I learnt the value of reflection, which brought me here. 

It helps to take notes. It helps to summarise these notes and reflect on what you have learnt. And it helps them to plan the next steps. So here I am, fifteen years on, once again on the Level III Senior Swimming Coach course with Swim England, once again keeping notes. 

Core Theme: Be Curious

Ask why at every stage: purpose of sets, purpose of models, purpose of recovery.

Test assumptions: myths vs. evidence, context specificity.

Reflect: Does this work for my swimmers in my environment at their current stage?

Sports Physiology Insights (Craig Robertson, PhD)

Don’t fear fast kids – intensity is not bad, but it must be age-appropriate.

Myths in swimming – volume, lactate, technique, aerobic capacity: all are context-dependent.

Aerobic base is non-negotiable – supports recovery, health, and resilience.

Volume progression in pre-pubescent swimmers – they produce lactate, but in smaller amounts; avoid overloading them with high-intensity work.

ATP-PC system analogy – like a match (9–12s) lighting a firework (90s glycolysis), before tumbling into a bonfire (sustained aerobic).

Energy Systems & Training Models

1: Energy System Model – ATP-PC, Glycolysis, Aerobic.

2: Critical Swim Speed (CSS) – sustainable training pace.

3: Ultra Short Race Pace Training (USRPT) – precise, high-rep, short-rest.

4: Polarised Training – 80% low intensity (A1/A2), 20% high (AT/VO2).

5: Skill/Technique Model – sometimes the proper focus is not intensity, but how well they swim.

Planning & Periodisation

  • Microcycle – typically 7–10 days, defined by the coach.

  • Mesocycle – typically 4–6 weeks (adaptation phase), but flexible.

  • Macrocycle – work back from the most important meet (Club Champs → Counties → Regionals → Nationals, depending on swimmer).

“Pick one thing to fix until it sticks, then add more.”

Set Design Principles

Training Quality = Before, During, After (Plan > Execute > Reflect).

Set = Distance × Intensity × Rest × Repeat.

Long passive rests = essential for true anaerobic work.

Keep it simple – swimmers remember one or two key tasks, not long scripts.

Example takeaway: A2/AT sets, such as 50×100m descending intervals (P1/P2), are not about entertainment, but rather about pace discipline and resilience.

Swimmer Development

  • Pre-puberty: aerobic volume and skill focus.

  • Youth: balance aerobic + introduction to anaerobic, technical consolidation.

  • Senior: Add full race-specific training and manage recovery/stress balance.

  • “All models work, with the right athlete, in the right environment, at the right time.”

Reflection for My Coaching Practice (PC1, C2, P2)

PC1 (10–12 years)

Build aerobic base, fun technical fly work (their known weakness).

Keep sessions simple (≤1500m), with clear focus points they can remember.

Emphasise pacing, skill mastery, and enjoyment.

C2 (14–16 years, County-level)

Already skilled, so focus on A1/A2 aerobic conditioning.

Manage rest/recovery – don’t overload anaerobic too soon.

Keep them curious – involve them in why we’re doing a set (build ownership).

P2 (12–14 years, County/Regional, 2 Nationals)

Sessions already demanding (e.g. 5.8km aerobic, 90-minute EMT, etc.).

Need balance: skill focus (starts/turns/kicks) + energy system development.

Link training to competition calendar  – September Club Champs → County Qualifiers → Christmas Cracker → Regionals.

Individualise: RS4 (near-Regional back/free), AS6 (Regional all-rounder), FS5 (National distance, inconsistent attendance), ES4 (Sprint Fly + Distance Free, emotionally fragile).

Personal Learning Reflections

🟢 What I do well already:

Session design with clear A2/AT progressions (seen in P1/P2 test sets).

Focus on technique threads (turns, skills under fatigue).

Building attendance and accountability across squads.

🟡 What I need to improve:

Use rest more intelligently for anaerobic sets.

Avoid overcomplicating sets; strip back to key objectives.

Bring in new models (CSS, Polarised Training) by January as tasked.

Check swimmers’ understanding of intensity zones (do they know what “A2” feels like?).

🔴 Challenges:

Managing individual differences in a mixed group (P2 spans County → National).

Supporting motivation and well-being (e.g., ES4’s anxiety, FS6’s bravado).

Balancing volume, intensity, and recovery in line with age/stage.

Post every day?

Visible to anyone in the world
Edited by Jonathan Vernon, Thursday 3 November 2022 at 06:46

Post at all! There was a time, here included, where I posted something every day. I still had this hangup going back decades that a diary, like bedside prayers, is something you do every evening without fail. I must have done if for 20 years on paper and for a decade online until I realise it wasn't getting me anywhere; it didn't achieve anything.

Is reflection supposed to 'get you anywhere'?

The mistake in a way was to ever imagine anyone would read this except for me.

Anyway, from time to time towards the end of a month, or in the first few days of a new month - and especially at New Year, I think (like tens of thousands of others), 'should I keep a daily diary?'

Frankly I am too busy doing, too exhausted to care to. I'd have to give up the end of day ritual of an hour of TV/Streamed drama. I'd have to give up my Scrabble App. And writing down the day wakes you up rather than sends you to sleep - it will impose itself on you and expand like foam of a can.

On verra.

I did a lot yesterday. Up at 5.00am something to create and post social media for someone, a bit more sleep then out early to walk the dog and track down the source of a local stream (for a blog/social media), then to volunteer the morning and early afternoon to a class of primary school children visiting the River Ouse. After which I had two swim coaching sessions to write, then deliver ... which took me to 9:30pm when I got home. I'm enjoying 'The Empress' right now about the Hapsburg Royal Family in Austro-Hungary in the 19th century.

And while here I looked at Free Online Courses on the Environment, and looked at post graduate study too. My time spent with Friends of this, or that or the other, on planning and environment committees with the Town Council (I'm an elected Green Councillor here in Lewes) has me thinking if I can revisit my undergraduate degree (Geography) and build on that.
