On today's Spotlight, we ask why runners are racing faster than ever? The same could also be said of cyclists, and we use an intriguing article by Amby Burfoot to explore and discuss the possible contributors, ranging from super shoes to the "Bannister effect". It leads us back to ground we've covered before (shoe tech, carbs), some areas we have yet to cover in detail (bicarbonate), and down some dark alleys that may contain the future (and possibly present) of doping methods.

We also talk about technology in sport, and about which sports have seen the biggest, fastest leaps as a result of innovation, taking a quick tour of some other devices that have 'recalibrated' sporting performances and human limits.

Finally, we discuss some of the science and performances in the Zwift Academy 2025, the latest iteration of a competition to identify and recruit aspirant cyclists into two professional cycling teams. We explore the tests used on the show, their value, and how hugely confounded the talent prediction is, even in a sport as measurable as cycling.
