What I coach

Whatever your goal, let's get you there.

Every athlete gets the same personal plan, TrainingPeaks setup and unlimited WhatsApp support, whatever the goal.

01

Get fit

Never trained before or getting back into it? A simple, realistic plan to build fitness and habits that last.

 02

Running

From your first 5K to a faster 10K or half marathon. Structured run training that keeps you healthy.

 03

Marathons

Build the endurance, pacing and fuelling to finish strong or chase a new marathon PB.

 04

Cycling

Get stronger on the bike with power or heart-rate based sessions, indoors or out.

 05

IRONMAN 70.3

Swim, bike and run balanced for the half distance, from sprint and Olympic tris up to 70.3.

 06

Full IRONMAN

The big one. Long-course volume, nutrition and race-day strategy to get you to the finish line.
The coaching

Built for you.
Not a template.

From your first 5K to your first IRONMAN. A coach who races at the top level, writes every session herself and actually answers your messages.

A plan written around your life.

Swim, bike, run and strength built from your schedule, experience and race goals. Work trip, sick kid, bad sleep? The week gets adjusted, not abandoned.

∞

Unlimited WhatsApp

No message caps. No monthly check-in. Just ask.

Live workout feedback

Every completed session syncs to TrainingPeaks and gets reviewed, so your plan responds to how you're actually going.

No BS, honest coaching

Straight talk on what's working and what isn't. Clear targets and sessions you can actually stick to.

Race-day ready

Pacing, fuelling, transitions and taper. The details I use as a pro, passed on to you.

Powered by TrainingPeaks

Your training, live in your pocket.

Every session lives in the TrainingPeaks app with exact targets. Train, sync, and I see it. Here's how a week works.

  • 1
    Your week lands in TrainingPeaks

    Structured workouts with clear targets for pace, power, heart rate and swim intervals, scheduled on your calendar.

  • 2
    Workouts sync to your watch

    Sessions push straight to your Garmin, COROS, Wahoo, Suunto or Apple Watch, or to Zwift for indoor rides. Just press start.

  • 3
    Completed data uploads automatically

    Finish the session and it syncs back. Each workout is colour-coded green, yellow or red to show how closely it matched the plan.

  • 4
    I review it and reply

    Comments on your workouts, plus a WhatsApp if something needs a chat. The plan is adjusted live, not at the end of the month.

  • 5
    Track your fitness over time

    Training load, fitness and fatigue trends show you're building toward race day, and help time your taper perfectly.

About Bridget

I'm a professional triathlete from South Africa, racing the IRONMAN Pro Series.

I started in short-course racing, competing for South Africa on the World Triathlon circuit and on Africa Triathlon Cup podiums, before moving up to the 70.3 distance.

In 2026 I raced the IRONMAN 70.3 World Championship in Nice, finished 4th at IRONMAN 70.3 Krakow and won the South African Cross Triathlon Championship.

I know what it takes to balance hard training with real life, and I coach the way I'd want to be coached: personal, honest and always reachable.
