This session is inspired by the Club Relays, a 4-person event which has been part of the fabric of the UK Triathlon scene for almost three decades.
The workout includes four sets, within each one you increase the effort from Tempo, through to Threshold and then (briefly) into VO2 Max, before a short recovery.
Repeat four times - one each to represent each team member in the virtual relay
