Zwift Duathlon – Starts soon
On 17th February this year, Zwift starts their Duathlon race series.
These might be described as mini-duathlons and certainly favour the cyclists over the runner. It’s a 6-week race series in a ‘league’ format
The race format itself is pretty straightforward.
35 minutes – cycle as far as you can from a mass start, non-drafting is system-enforced and you can use a standard TT bike or one you have ‘earnt’.
10 minutes – rest and transition as easily as you can!
15 minutes – run as far as you can.

My favourite kit and nutrition
- Maurten — the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
- Garmin 90-degree charging adapter — the small adapter that keeps your charging cable tidy at the stem. Essential for race day.
- Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session.
- Ravemen FR300 — front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters.
- Garmin Varia RTL515 — radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch.
- Stryd — the footpod that brings running power to your Garmin. The single most useful running upgrade I have made.
- Favero Assioma Pro RS2 — the power meter pedals most serious cyclists end up choosing. Accurate, easy to move between bikes.
