Regardless of your use of irregardless vs irrespective...
1) why would we ask a Brit...who cares. I'm Canadian...I can show you a different level of bad conditions if you want. Anyway we are talking a cross country race in PA. Conditions were muddy in some areas, but not as bad as I had expected.
2) Tuohy can race where ever she likes. Obviously she prefers NXN to FL. Yes she races fine in the cold, doesn't mean it's her favorite.
3) These pro's/runners signed up for the Club Nat's XC, they have been running XC for 10 - 12 years...pretty sure they are decent at preparing themselves. Not your best point.
4) So Tuohy would not have run better on the roads?...really not your best point
5) Not going to argue your point on core heat, but then again, these are pretty experienced runners and I'm sure they know when they are cold. Fairly certain I've seen Radcliffe hanging her belly out in the rain.
Was a good video, which was was definitely better than any point you made.
You're welcome in advance...
