And that number is down from more than 9k last year. For comparison's sake, just 422 people ran in all the various races at the 2019 USA XC Champs.
From Fastrunning: "This year’s championships is the 131st edition of the senior men’s event, while the senior women race the for the 86th time, with 8027 runners entered across the 10 races. The figure is down on last year’s record figure of 9565 at Parliament Hill."
I guess it's just dead for the pros who largely appear to be afraid to race the Africans when they know they a) will get crushed and b) not make much money.
Hell, tiny Scotland, population of 5.3 million, is crushing the US in terms of entrants as they have nearly 1000 (970).
