#22Inline skates on flat ground are technically "no external energy". And they can race a marathon in under an hour, so that's 26+ mph (42 kph)
The proposed device is predicted to allow almost double that speed. I think it’s pretty cool.

#25Naruto run. Don't even need to read the article.
"Without external energy (but with external device attached)" is ... a bit disappointing. At what point does it cease to be running and start to be run-assisted catapulting? Or catapult-assisted running? It seems like more than just running.

#26Isn't this why Oscar Pistorius was considered to have an unfair advantage by many?

The article says that the Paralympic running top speed is below the non-paralympic top speed.

No, this is a different sort of spring-loaded mechanism that allows you to put energy into it when you retract a leg, then unleash that stored energy when your foot next hits the ground.
"However, the current top speed of augmented running, 11 m/s, achieved using a spring prosthesis in series with the legs (13), is 10% below the top speed of natural running. A spring in series with the legs can mitigate collisional energy losses but requires the legs to provide a large force to support the body, unlike the wheel of a bicycle (10, 13, 14)."

#29Nike Vaporfly. I'm surprised it wasn't mentioned that 2 recording breaking marathon runs were by athletes wearing the Nike Vaporfly shoe. The shoe was ultimately banned due to the giving too much "bounce" (free energy) to the runners. https://www.reuters.com/article/us-athletics-shoe/nike-proto...
In fact, the shoe was not banned and it is one of the most widely used marathon racing shoes out there. Nearly all other running shoe companies followed suit and made more efficient racing flats with carbon plates and high energy return foams. Some restrictions did come out, including limits on the "stack height" racing shoes and more stringent restrictions on the track. The current generation of these, the alphafly 3, were just used to break a world record in the Chicago Marathon by Kelvin Kiptum. Those are unreleased as of yet.

Yes, skating is mentioned in a graph near the end.
