Is this old news? I just noticed that Hasay and Sisson both racing the USATF 20K championships on Monday in CT. Aliphene Tuliamuk is also in it. Have Hasay and Sisson ever raced head-to-head? Probably, but I can't recall. Given a build-up prior to Chicago, my guess is that Hasay might be racing on 'tired legs.' Same for Rupp on the men's side - but suspect he will still come away with the win. I'm not sure who is winning on the ladies side - both Hasay and Sisson have been running very well, and I'm not sure about Tuliamuk at all. Any thoughts?
