Red Bull and fitness app Strava has teamed up to challenge users to commit to workouts for as many days as possible within a 28-day period.
The 'Zero Missed Workouts' challenge is due to run through 6 February.
The companies, in an announcement, said the launch coincides with Quitter’s Day on 9 January and will offer support and motivation as participants log activity, earn badges via the Strava app, view fitness content from Red Bull athletes and encounter surprises.
Strava users who log activities seven out of 28 days will be eligible to claim a can of Red Bull Zero; those who log 14 out of 28 days will receive a motivational video from a Red Bull athlete; and those who log 21 out of 28 days will have the chance to submit for the opportunity to participate in any HYROX race of their choice.

Zero Missed Workouts is said to be 'inspired' by Red Bull Zero, which provides the same "wiiings" as Red Bull Energy Drink but with zero sugar (instead it uses monk fruit extract and other sweeteners).
The energy drinks firm said Red Bull Zero (8.4 fl oz) is now NSF Certified for Sport® and free from 290+ substances banned by major athletic organizations.
The Recap
- Red Bull launches a 28-day Strava challenge called Zero Missed Workouts.
