Retinitis Pigmentosa is commonly referred to as RP, much easier to say. What is RP? Retinitis Pigmentosa (RP) is an inherited, degenerative condition that affects the retina – the light-sensitive part of the eye. The retina consists of millions of light-sensitive photoreceptor cells, which transmit light to the brain via the optic nerve. RP causes some photoreceptor cells to fade gradually and die, losing the ability to transmit visual messages to the brain. RP usually begins to affect people in their teenage years. Most people with RP experience gradual peripheral vision loss (or “tunnel vision”). They also have difficulties seeing at night or in areas with poor illumination. Central vision is usually unaffected, so the person may still be able to read. However, this can also deteriorate and eventually lead to total blindness. Sourced from Guide Dogs NSW/ACT.

RP is with me all the time, I have lots of visual noise, similar to a TV that is not tuned into a station, it is an overlay to everything I see. In darkness it is most obvious to me and less so in daylight. With 20 degrees of peripheral vision I constantly scan, memorising my surrounds to make a complete picture. My central vision is reasonable although there are a some patchy spots. I have cataracts in both eyes. The functional implications of RP on me is detailed on my web page.

Essentially this blog is about one aspect of my life and running, and the influence of RP on this. I have a web page almost completed that has more of the permanent information about this, some more detail on RP and me, some things I’ve done and going to do, a video of an RP simulation of a trail run I do often. Importantly the main aim of this blog and web page is, by sharing an aspect of my life this may then inspire others to try something unexpected, uniquely challenging to themselves and share with the world.

Checkout my RP simulation video on either link, some feedback would be great.

Web page will be up soon. (Now up at)
Photos and updates on my events are in progress. Next will likely be about being a Bitumen is Boring Ambassador in the Salomon Trail Series Silvan event.

Thanks for reading.
