Thought she was out this past xc season with injury but turns out it's a rare medical condition "popliteal artery entrapment syndrome". She posted about it on her instagram in the comments (https://www.instagram.com/p/BXxdnM6Fzie/?taken-by=trackmurphy)
Anybody else dealt with this? Any medical professionals to give feedback?
Wishing her the best recovery and that she'll be back to her former level soon!
