Nike Zoom VaporFly 4% / sub-2h marathon / #fake-news

 

 

 

I wasn’t sure which title I should use... what do you think?

 

 

• Kipchoge is the best marathon runner in the world... regardless of his shoes!

 

• When marketing contaminates science 

 

• * Zoom Vaporfly 4% ?  #Maximum1%   #PlaceboEffect  #ShowMeTheEvidence

 

• 4% energetic cost = 3% time improvement = many runners should’ve already gone under 2h01!

 

• New marathon world record by the one and only Eliud Kipchoge !

 

• Marathon Under 2h00 #GoodIdea #NoCheating #Pleaseplayby-IAAF-rules 

 

• CAD $330 / USD $250 / 250 Euros : Whaaaaattt??? ... for an actual production cost of Under $30 ?

 

• Do not let marketing influence your perceptions! That’s also valid for elite athletes! 

 

• Every 100g of running shoe mass can decrease oxygen consumption by 0.7-1.0%... for the rest, beware of #fakemeds

 

• AdidasBoost, ZoomVaporFly4% or any other shoe with the same mass = similar performance (less than 0.5% difference)
