Squad & Session Finder
Which sessions are actually for you — and what a realistic week looks like.
Triathlon has an intimidating number of entry points, and most people either pick the wrong one or do nothing. Tell us where you are and what your week genuinely allows, and this ranks the sessions that fit, in the order worth starting them — built around the days you have rather than the days a training plan assumes.
4 days a week to work with
Start with Beginner triathlon program — then build to 4 sessions a week
Ranked against your swimming, your goal and the 4 days a week you can genuinely hold. The order matters more than the scores: start at the top and add the next one when the first has become a habit, rather than attempting all of them in week one.
Read this first
Your race is in open water and your pool swimming is still developing. Book supervised open-water sessions rather than going down to the bay with a friend — cold-water entry and the absence of a wall are what catch people out, and both are survivable in a supervised session and genuinely dangerous alone.
How well each session fits you
Longest bars first. These are a ranking, not a scorecard — anything above about 60 is worth doing, and the top two are where to start.
View as a table
| Dimension | Score | Your answer |
|---|---|---|
| Beginner triathlon program | 90 / 100 | Structured multi-week program that takes complete beginners to their first finish line. |
| Supervised open-water session | 85 / 100 | Coach and support craft on the water. Sighting, starts and wetsuit practice in a controlled environment. |
| Learn-to-swim / technique squad | 82 / 100 | Small-group coaching for non-swimmers and stroke rebuilds. |
| Brick session (bike into run) | 72 / 100 | The bike-to-run transition rehearsed under fatigue — the session most first-timers skip. |
| Coached pool swim squad | 70 / 100 | Coach on deck, lane-based sets, technique correction every session. |
| Group ride | 70 / 100 | Bunch skills, sustained riding and route knowledge with the squad. |
| Coached run squad | 66 / 100 | Pace work and durability, coached, on legs that have already ridden. |
| Come & Try session | 45 / 100 | A free, no-commitment first session with a coach and other beginners. |
| Strength & conditioning | 40 / 100 | Injury-resilience work that keeps a build honest. |
| One-to-one coach consult | 40 / 100 | Sit down with a coach to turn a plan into your plan. |
What your week could look like
Built around 4 days. A week you actually complete beats a better week you abandon in February.
| Discipline | How often | Why |
|---|---|---|
| Swim | 2× a week | Your limiter. Both sessions coached, if you can — technique returns more here than metres do. |
| Bike | 1× a week | One steady ride, building the long one gradually. |
| Run | 1× a week | Keep it easy. Running carries several times the impact load of the other two. |
| Brick | Every 2–3 weeks | Run straight off the bike. Replaces one of the runs above rather than adding to the week. |
The order to add them in
Add one thing at a time and give it three weeks before adding the next. The most common way a promising start ends is committing to five new sessions in one week, holding it for a fortnight and then stopping entirely.
If you can only protect one coached session, make it the swim. It is the discipline where you cannot see your own technique, where the fault is invisible to you and obvious to a coach on the deck, and where the return per hour is highest for an adult learner.
Tri Alliance sessions that close these gaps
- Beginner triathlon program A structured multi-week route to a first finish line, rather than assembling one yourself.
- Supervised open-water session Sighting, cold entry and group starts are separate skills from pool swimming, and race day is the wrong place to meet them.
- Learn-to-swim / technique squad Swimming is the discipline where adults need instruction rather than effort, and it is the one thing that cannot be worked around.
- Brick session (bike into run) Running off the bike feels genuinely strange the first time. Doing it in training means it is not new on race morning.
The short answer
The right first triathlon session depends on swimming ability more than on general fitness, because swimming is the discipline where adults most often need technique instruction rather than more effort. A non-swimmer or someone who cannot cover 200m continuously should start with learn-to-swim or technique coaching before joining a lane-based squad. Athletes who can already swim continuously benefit most from a coached pool squad, where stroke correction happens every session. Anyone racing in open water needs supervised open-water sessions regardless of pool ability, because sighting, cold-water entry and group starts are separate skills. For a first race, three to four sessions per week is sufficient — typically two swims, one to two rides and one to two runs — and adding a brick session, where a run follows immediately after a ride, is the single highest-value addition once a base exists.
How to use this tool
- Say where you are now and what you are aiming at — the answer for general fitness is different from the answer for a 70.3.
- Be honest about your swimming. It is the discipline that decides where you start.
- Enter the days you can train in a normal week, not in your best week.
- Read the fit scores — the highest bars are where to start, not everything you should eventually do.
- Take the suggested week as a starting shape and book the first session on the list.
Common questions
Do I need to be fit before joining a triathlon squad?
No, but you do need to be able to swim. Squads are lane-based and run to a set, so a swimmer who cannot yet cover 100m continuously will spend the session out of their depth in every sense. Bike and run fitness genuinely does not matter — those sessions are structured so that everyone works at their own effort — but the swim is the one where arriving too early makes for a miserable hour. Learn-to-swim first, squad second.
How many sessions a week do I need for my first triathlon?
Three to four is enough for a sprint, and it is far better to hold four sessions consistently for twelve weeks than to manage six for three weeks and then stop. A typical first-timer week is two swims, one or two rides and one or two runs. Once that is a habit, the highest-value addition is not a fifth session of the same thing — it is a brick, where you run straight off the bike, because that sensation is the one thing no single-discipline session prepares you for.
What is a brick session and do I need one?
A brick is a run that starts immediately after a ride, with no meaningful gap. It exists because running on legs that have just cycled feels genuinely strange the first time — heavy, uncoordinated and slower than expected — and race day is a poor place to discover that. You do not need many: a handful over a training block is enough to make the sensation familiar. It is also the session most first-timers skip, and the reason so many people walk the first kilometre of their first run leg.
Can I train for a triathlon on my own?
You can, and plenty of people do. What you lose is stroke correction — you cannot see your own swimming, and no amount of solo laps fixes a technique fault you are not aware of — plus the accountability of somebody expecting you at 6am. A reasonable compromise is coached swimming, because that is where the technical return is highest, with the bike and run done on your own to a plan.
I have done a few races. Is a beginner squad going to be too easy?
Squad sessions are written with multiple lanes and effort targets, so the set scales to the athlete rather than the other way around. What changes with experience is not the session but what you use it for: a first-timer is there to learn how to swim a set at all, while an experienced athlete is there to hold prescribed paces off a controlled rest. If you already have thresholds and zones, bring them — the session is built to be run against your numbers.
