Bespoke 1-2-1 Coaching

Our Philosophy

At T3, we don’t believe in one-size-fits-all training plans, and we don't hide our best support behind expensive premium tiers. Your goals require a fully committed, highly individual approach that integrates seamlessly around your career, family, and life.

For £200 a month, you get our full attention, daily schedule flexibility, and direct 1-2-1 access to a coach who lives and races the sport they're guiding you through. No compromises, and no hidden upgrades.

More than a training plan…

When you join T3, you're not buying an online spreadsheet — you become part of the team. Triathlon can be a lonely sport, but athletes progress faster, and enjoy it far more, when they train and race together.

  • The T3 Community: Instant access to a proper network of athletes of all abilities — swapping training data, debating gear on the team chat, or meeting for a coffee on the start line of a major race. You'll always have a team behind you.

  • Priority Camp Booking: Our UK weekends and annual Mallorca camps sell out fast. As a T3 coached athlete, you get first dibs before bookings open to the public.

How to get involved

Your coach builds a TrainingPeaks plan from scratch, around your physiology and your career and family commitments. No generic templates.

Step 3 — Your Bespoke Plan

Step 4 — Train & Adapt

Start training with real flexibility. We analyse your data, adjust in real time, and back you all the way to the finish line.

We pair you with the T3 coach who best fits your distance, experience and personality — not just whoever's free.

Step 1 — The Intro Call

A quick, no-pressure chat about your current fitness, your upcoming races, and whether we're the right fit to work together.

  • Everything we offer. You get a completely bespoke, week-by-week training plan delivered via TrainingPeaks that is built entirely around your career and family commitments. It includes unlimited communication (texts, calls, emails) with your coach, dynamic daily schedule changes, custom race-day pacing and nutrition plans, and full access to our T3 Team community and premium brand discounts.

  • No hidden sign-up fees and no locked-in long-term contracts. Our coaching runs on a rolling monthly subscription. We believe the quality of our coaching and the progress you see week-by-week is what will make you want to stay. If your circumstances change, you can pause or cancel at any time.

  • We coach all abilities. While our coaches have raced at the elite and professional levels, our athletes range from total beginners targeting their very first sprint distance to seasoned age-groupers chasing Ironman World Championship slots. If you are committed to turning up and doing the work, we can build a plan for you.

  • As often as you need to. We do not place caps or limits on text messages, emails, or phone calls. Whether you need a quick adjustment before a track session, a deep dive into your power data, or a phone call to talk through race-day logistics, your coach is fully accessible.

  • Because our coaching is completely 1-2-1, there is no "standard" T3 template. A typical week is built entirely from scratch around your specific life schedule, available training hours, and target race distance.

    We can know more once we jump on a call to discuss your needs. However, even then, it will be a constantly iterating process - developing and adapting in real-time as you progress within the sport.

  • While the team lives and breathes multi-sport, we also provide pure 1-2-1 coaching for individual running, cycling, and swimming goals.
