TRI247 Workout Series: Marc Jenkins - Turning the Screw
Group Workout
Every Wednesday at 7:05pm UK-time, TRI247 present a triathlon focused workout brought to you by a guest 'coach.' This will include sessions by pro triathletes, coaches and notable characters associated with the sport.

The workouts are typically about 60 minutes long and designed to add variety and interest to your weekly training schedule.


This week’s session will be lead by Marc Jenkins (aka ‘Jinx’), one of the UK’s top professional triathletes for more than two decades, representing Great Britain at the 2004 Olympic Games in Athens. Marc was a British Champion, twice represented Wales at the Commonwealth Games (2002 and 2006) and represented Great Britain at multiple European and World Championships, ITU World Cup events and more. In 2015 he was presented with British Triathlon’s Gold Pin Award in recognition of his contribution to the sport.

Tonight's session is called 'Turning the Screw', as the main set comprises of six, four-minute intervals, but each will start at 85% FTP and then ramp up steadily to 120% before a short rest... and then go again!

The session was set by Marc’s coaching partner Rhys Jones at Jinx Sport ( a new window)


Zwifters line up in the starting area just like a normal event and once the event starts, workout mode begins. Everyone stays together regardless of power output. That's right, if you're outputting 100W and another Zwifter is outputting 400W you will stay in exactly the same position relative to each other. Only if you stop pedaling and fall 6 meters behind the group will the rubber-banding stop.


We highly recommend doing one of the FTP tests as the estimated FTP can be inaccurate and make the difficulty level of the workouts too high for your current fitness level.
