Introducing Chris Hall's 107 for 107 challenge and special edition jersey

He's doing pretty great so far. Every week he's been riding 749km - that's the distance from London to Geneva, Switzerland.

He'll be doing that for 15 weeks in a row all in all, and fitting a full-time job somewhere in there too!

So why's Chris doing all of this?  To raise awareness of 107 very special children, the students at the Pace Centre. The Pace Centre is a school which transforms the lives of kids up to the age of 18 with motor disorders such as cerebral palsy.

Completely self-funded, it's founded on the firm belief that every child has the ability to learn and make progress.

 As well as being physically taxing, this challenge is a constant mental battle for Chris too. The support from his mates, and the strangers, who turn up each day and lend him a wheel to sit on are his driving force.

Chris also wanted a piece of kit not only to commemorate this challenge, but something to help give him that extra boost of motivation when the going gets tough.

After chatting and riding with Chris, we had an idea, and got to work creating the Attacus + 107 Jersey. A reminder of those 107 children. A reminder that while he may be struggling, we all struggle.

Together with Cardiff-based designer Jo Ward, we created a bold monochrome print which represent a cluster of roads. With 107s fixed within the geometrics - so Chris only has to glance down if his motivation momentarily dwindles.
