It's starting to get more winter like around these parts as of late, so on my ride this morning I was thinking about the one hour threshold. Has anyone else ever noticed that there can be a one hour threshold where anything after that and things start to get cold.
This didn't happen today or anything, I was just remembering my last 3 winters of riding and how this never gets mentioned on this forum. It should get mentioned because it is important personally to calculate and allow for this phenomena.
When we talk about what to wear, it is seldom taken into account how long it was worn for. For example, in the "what i wore" sticky the length of the ride is sometimes listed but probably not given enough attention.
From my experience, what works for 30 minutes may or may not work for 1 hour and 30 minutes. Often for me things start to try and go numb after one hour. This seems to happen on the hands and feet, when i am wearing something that is marginal for the given temp. My Lake Winter boots are a good example. They can be toasty warm at 15 F for 45 minutes, but ask me again, at 1 hr. and 45 minutes. I'd have a different answer.
