The gist of it is that Brent (able-bodied) and Kyle (cerebral palsy) have been racing IMs, marathons, etc. together for years and they run a foundation (http://www.kylepeasefoundation.org) that helps disable kids participate in sporting events.
At Raleigh 70.3 a couple weekends ago, they were awarded a 2018 Kona slot, which has been their dream for years.
I was talking with my bike mechanic last week (the same guy who does all the work on their rigs) and he mentioned that they're going to have to raise a lot of money just to make the trip to Kona (themselves plus support crew). They also have to re-engineer their bike to make it lighter/faster (it weighs 75 lbs. now), and ship all of their equipment to Kona. If anybody's interested in making a donation their foundation's Kona-specific fund, you can do so here:
