Include them in the Olympics, but as a separate event
I agree with the posters who suggest that it's akin to doing a marathon in a wheelchair or racing on a bike: perfectly legitimate sports, just different from running.
So lets have some of these events such as blade running, wheelchair marathon and murderball in the regular Olympics alongside running and cycling instead of pushing them off to the far-less-televised Paralympics. It's not like there aren't a lot of sports already where equipment makes a big difference. It would also help to offset the ludicrous number of swimming medals awarded for doing essentially the same thing in arbitrarily constrained ways.
And if anybody thinks there isn't room in the Olympics for more events, I know that I would happily cut some of the ludicrous non-sports such as rhythmic gymnastics. Eliminate any event that is scored on artistic merit, performed in time to music, or requires waterproof lipstick, along with Synchronized Anything, and there will be plenty of room for the real athletes.
