Two World Records in Zurich: Alison dos Santos and Masai Russell / Femke Bol's Fascinating 800m Transition / Cycling We Haven’t Seen for Ten Years in The Vuelta

Chapters

1. 6:29Alison dos Santos takes Karsten Warholm's 400m hurdles world record with 45.80s, catching Warholm by the fourth hurdle. We get into stride patterns, why Edwin Moses ran 13 strides and Kevin Young 12, which leg leads on the bend, and how shoes may have interacted with fatigue to drive hurdles forward more than sprinting.
2. 15:59Masai Russell's 12.09 is the first 100m hurdles world record set without a following wind since 1986. She was anticipated as the next WR holder, and she delivered, with the promise of faster and an 11.xx on the horizon.
3. 24:35Femke Broders-Bol takes the 800m out from the front against Audrey Werro, and why the tactic was right for her even though it suited Werro perfectly.
4. 27:23Karsten Warholm on a chaotic calendar, with our thoughts
5. 34:57Bol revealed her LT and long run paces, to much amazement. But her coach Laurent Meuwly explained this in detail, and sets us up for a fascinating discussion on Bol's transition and ceiling. We talk about her statement that her endurance is "so bad for 800", why her 400m speed matters far more, and tee up our upcoming Applied show where we will dissect her coach's explanations to Citius Mag
6. 43:23The Vuelta without Tadej Pogačar, where tactical mistakes carry a cost again, and cycling as we haven't seen for a decade. Plus, Tom Pidcock's mountain bike win.
7. 52:11Novak Djokovic's US Open exit, and a physio who refused to treat Terence Atmane's cramp. Is cramp an injury, or a conditioning problem?
8. 58:22Aaron Donald returns to the NFL at 35, and how much conditioning an athlete loses.
9. 1:02:54Yomif Kejelcha's 56:51 half marathon, and who breaks two hours this autumn? Ross reckons two might do it.
10. 1:09:16Jeff Browning's heart attack at UTMB, and Jenny Simpson's collapse. Fitness is protective, but it isn't immunity, with David Epstein's terrific article
11. 1:13:35South Africa against New Zealand, and racing robots in China, where our advice is to stop short of a wall.
