You want to do a triathlon. You also have kids, work, and about seven minutes of spare time on a good day.

This is the post I wish I could hand every mum who's ever DM'd me at 10pm asking if she's "too old, too slow, too busy" to sign up for her first triathlon.

You're not. You don't need 20 hours a week. You don't need a garage full of kit. You need the right distance, three good sessions, and a plan that flexes when the school calls to say someone's just thrown up.

Here's how it actually works.

Step 1: Pick the Right Distance for Your Life

Not all triathlons are created equal. Signing up for a Half Ironman when you're two years old into motherhood with a full-time job is setting yourself up to fail. Start where you can actually finish.

Distance - Swim - Bike - Run

Sprint - 750m - 20km - 5km

Olympic - 1.5km - 40km - 10km

70.3 (Half Ironman) - 1.9km - 90km - 21.1km

For your first triathlon as a busy mum, do a Sprint. If you're already fit, an Olympic. Anything longer needs a life stage where you have more control of your time.

Step 2: Train Smarter. Three Sessions Beats Six.

The idea that you need to be swimming, cycling, and running six days a week is a myth from the pro world. It doesn't apply to your life.

For most mums training for a sprint or Olympic distance, three targeted sessions a week gets the job done. Any more is a bonus.

The three-session week

Swim (30-45 mins): One technique-focused session. Drills, then endurance.
Bike (45-90 mins): One interval or hill session, OR one longer steady ride at the weekend.
Run + brick (45 mins): One brick workout (short bike straight into a run). Best value session in triathlon training.

Strength training on top of that in 15-minute bodyweight blocks two or three times a week. That's it. That's the whole plan.

If you get a fourth session in some weeks, take it. If you don't, you're still training properly.

Step 3: Make It Fit Around the Family, Not the Other Way Round

The number one thing that breaks mum training plans is trying to train like you don't have kids. You do. Plan for that.

Early mornings. Not fun. Works. Get one session done before anyone else is awake and the day can implode without wrecking your training.
School run swap. If your partner or grandparent can do drop-off or pick-up once a week, that's one guaranteed session.
Turbo trainer in the garage / spare room. The single biggest gamechanger. No excuse about weather, safety, kit. Kids can play at your feet.
Kid-friendly sessions. Run with a running pram, ride with the older ones on their bikes, take them to the pool while you swim.
Batch it. A weekend long ride while your partner has the kids. Then you take over Saturday afternoon so they get their thing.

Have the conversation with your partner or support system before you start. This isn't a hobby you're squeezing in around them. It's a training block with a race date. Treat it that way.

Step 4: Fuel Yourself Properly

Most mums I coach are training on top of years of underfuelling. It shows up as tiredness, injury, cycles going sideways, and no performance progress no matter how consistent the training is.

The basics for triathlon training as a mum:

Carbs are not the enemy. They fuel your sessions. Eat them.
20-30g of protein at every meal. Especially post-session. Non-negotiable for recovery.
Fat. Avocado, nuts, olive oil, oily fish. Your hormones need it.
Hydrate. 2-3L of water daily. Electrolytes on training days.
Snacks in your bag at all times. Boiled eggs, oatcakes, protein bars, bananas, dark chocolate. Underfuelling on top of mum-life is what breaks people.

Don't diet while you're training for a triathlon. If body composition is a goal, that's a conversation for after your race, not during your build.

Step 5: Give Yourself Grace

Some weeks you'll nail every session. Some weeks the kids will be sick, you'll be running on four hours of sleep, work will be a mess, and you'll miss three sessions in a row.

That's not failure. That's normal.

Consistency is not "hitting every session". Consistency is "showing up over months, even when weeks fall apart".

If you missed a session, you didn't fail. If you missed a week, you didn't fail. If you show up the next week and get back to it, you're winning.

The Short Version

Pick the right distance. Sprint for your first as a busy mum. Don't be a hero.
Three sessions a week is enough. One swim, one bike, one brick. Strength in 15-min blocks.
Plan around the family. Early mornings, turbo trainer, kid-friendly sessions, partner support.
Fuel properly. Don't diet while training. Carbs, protein, fats, snacks in your bag.
Grace over perfection. Missed sessions don't matter. Missed months do. Keep showing up.

Sound familiar?

You want to do a triathlon but you can't see how it fits with the kids
You've tried generic training plans and they don't work with real family life
You need a coach who understands that missing sessions is part of the deal
You want female-specific, mum-specific coaching, not a generic plan built for someone with all day free

If you ticked two or more, this is exactly what my coaching is built for.
