Has anyone done it before on a SUP, or got info from doing it before?
Would ya use an inflatable or custom shape a full kevlar stick? with flip up spring loaded fin/s?
what size board would ya use?

Is this idea completely ridiculous?
how would you take the rapids? on the knees or lying down skeleton style?
134km over 2 days doesn't sound too bad.
Maybe a SUP Team challenge entry (share the ride with 4 ppl) sounds like a better idea?

team effort for sure!

You would have to be sponsored, the board, paddle and personal carnage would be epic.

There you go Rob your next feature!

Thanks for posting that video - unreal. It looks like a lot of fun if a tad dangerous at times.....the rocks being the main thing that would scare me.

I have done the Avon Descent the last 3 years in a row. I am also a keen SUP surfer and downwinder. My opinion is that it is not worth doing the Descent on a SUP. The tea trees are a huge issue hard enough in a kayak. Rocks also would be very dangerous falling from a standing position toward a myriad of rocks above and below the surface would mean wearing a lot of protective gear. Also you would not be able to wear a leggie as it it also dangerous and would be snagged very quickly and as already mentioned the last 20 odd kms is upwind. It may be possible but would just not be much fun you would trash your gear and it would take a really long time (possibility of being timed out).
However, down river SUPing is obviously possible and there are other races that may be suitable. One that comes to mind is the Northam to Toodyay race which is a lead up race to the Descent. Wind direction is obviously always a factor and also water levels. I like to kayak rivers and may try and SUP some sections but will pick the sections and the conditions so its fun.
