1	A new sub‑2 h marathon barrier is being broken	“stockresearcher: 3 people beat the previous world record in this race! This is some combination of improved tech and extraordinarily good weather.”
2	Super‑shoes and carbon‑plate technology are reshaping elite performance	“adzm: Looking this up, fastest human is still Usain Bolt at 27.78mph (at one point in a 100 meter dash).”
3	Elite marathon times are now seen as attainable by many	“PaulDavisThe1st: My predicted half time is under 2 hours and I was sedentary for years before starting to run 9 months ago, and I'm 40 years old.”
4	Massive carbohydrate intake & gut training are essential	“nradov: The leaders were burning a lot more than 100kcal per hour. I think you mean 100g of carbohydrates per hour.”
5	Doping suspicions and ethical debate surround the results	“ap99: Like, if we find out the top two finishers here doped very few would be surprised.”
