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.
