However, the 4% shoes need a new name. 2.7%.
That's from an article on Podium Runner that is pretty interesting. It talks about how Ward is working on helping Saucony close the gap. Apparently, they've already got a prototype out that is already really good.
That's the good news.
The bad news is it appears that Ward's 2:09 from Boston should be struck from the record books. Now we all know that won't happen but I'm not sure why no one at the IAAF is enforcing their new rule about pros only being allowed to run in shoes that are commercially available. Laura Muir's UK indoor mile record hasn't been stricken from the books either.
"Rule 143: Clothing, shoes and athlete bibs
- Any type of shoe used must be reasonably available to all in the spirit of the universality of athletics. Shoes must not be constructed so as to give athletes any unfair assistance or advantage."
