In fact simple science indicates just the opposite: anybody who wore the Vaporfly shoe should be recognized for a PR equivalent to having run a flat course. Ritchie's decision was a pragmatic one. If you calculate the leg speed velocity required for his run and chart it along the angle of declination of the CIM mostly downhill course, you'd see that the spring effect of the 4% shoes would actually cause his lead leg to be off the ground for TOO long before his foot hits the pavement. This critically inefficient overstriding caused by too long in the air between footfalls as a result of the spring effect would actually have caused him to run SLOWER in the Vaporflys. As to the other runners, in this case two wrongs really do make a right, as the Vaporflys would slow them down roughly equivalent to the same amount that the net downhill sped them up, leading to a time equivalent to that they'd run on a flat loop course.
sorry seems to be the hardest word wrote:
Mr. Ritchie wins the CIM without stooping to the level of many others who attempted to gain unfair advantage by wearing the should be illegal Nike Vaporfly 4% with the controversial carbon fiber plate in the midsole that many of his fellow runners wore.
Anybody at CIM who wore these shoes that feel like they have a spring in the heel should have their results voided.
immediately.
