Billy suffered a slow and regressive stroke at the age of 17. Every day he woke up he couldn’t do something he could the day before; type on a keyboard, tie his shoes, brush his teeth, run. After about 4 weeks the episode finally ceased and left him with a full left side hemi paresis state.

Having been an athlete his whole life the burden of losing the ability to take part in sports was a tremendous strain to cope with. For many years he simply survived with his disability but in his words he was “only surviving life, not living it”.

Then in 2011 he attended a Paratriathlon camp for the Challenged Athletes Foundation, and got on a bike for the first time since he was 17 years old. Since then he’s been living life to the fullest!
