Building on the success of the inaugural challenge, this year's 5x50 event will see groups and individuals from Scotland to Spain and Austria to Australia, embark on a 50 day activity-based challenge that is suitable for everyone. The 5x50 event challenges you to run, jog, walk or cycle 5 km (or participate in alternative activity i.e rowing for 30 minutes) EVERY day for 50 days. Participants are supported by an online community that brings everyone, from couch potatoes to marathon runners, together to achieve a healthier and happier lifestyle.

Personalities from sport and entertainment, including Olympic athlete Sally Gunnell and TV Presenter & marathon runner Jenni Falconer, have lent their support to the Challenge, recognising it as a clear way of changing exercise habits for a lifetime.

The 5x50 Launch day will see challengers complete their first official 5 kilometres on the 31st March . Participants are supported via a website to complete their daily 5k individually or in groups. The online community will allow users to register for the event, link with other challengers, receive training advice and importantly, motivate one another to keep going over the 50 days. On the 19th May 2013, participants will come together, celebrate and complete their final 5 kms at locations across the UK and select international sites.

To participate, a minimum registration fee of £5 is required, which will go towards supporting the 5x50 challenge's charity partner, Comic Relief. After registration, participants have the option to raise funds for a charity of their choice.

The core team behind 5x50 come from different backgrounds and have varying levels of fitness. A group of friends that quickly realised they shared a passion for improving fitness. They were inspired by co-founders, Kelly Mason's and Raymond Wallace's efforts to complete a similar challenge in early 2012. This shared passion resulted in the creation of the 5x50 core team.

Throughout the challenge, the 5 x 50 core team aim to motivate participants by sharing stories, training tips and encouraging participants to get together for their daily 5k. Founder Kelly Mason comments "This challenge started with a vision to make sport part of everyone's daily life. Not everyone will run a marathon, however anyone can complete the 5x50 challenge and experience the physical and psychological benefits that come from taking part".
