If the temperature drops 49degrees, my speed will drop 20mph, based on a starting speed of 20mph. It just ain't go'ta happen!
same thing happens if temps rise over 30C 85F for me ... bike is parked. luckily it is at most 2 days a year like that.If the temperature drops 49degrees, my speed will drop 20mph, based on a starting speed of 20mph. It just ain't go'ta happen!
^^^^Aero drag is directly proportional to air density, so if you increase density by 10% (temperature drops by 49F or 27C) you will slow by about 1 mph (using 20 mph as the starting point).
Over many years of riding a weekly 10 mile time trial, I found that the fastest conditions (for me anyway) was 80F (27 C) and high humidity. The high humidity reduced the air density a little further, but above 80 the heat was too much to take for an all out effort. I suppose that if I lived somewhere dryer than the Great Lakes region, I could have taken higher temps but I never got to run that experiment.I aways go for my KOM's when it's hot. Figures.
That's not much of a ride window he suggested.Cardiologist introduced me to the 80/40 rule. After the heart attack I was not supposed to ride if the temperature was outside this parameter. I had tuned him out so I don’t really remember the reasons
I solved the problem by ignoring the 80 side and moving south to take care of the 40 end. I don’t miss going out when the temperature is in the 20s
why not? seems to describe our climate in this PNW region, actually. Though I will ride down to maybe 35F .. and mountain bike down to 25F, but it rarely gets that cold here and also maybe 5 days a year does it pip over 80F. My hard limit if 85F, that's getting into miserably hot imho. 70F for mountian biking.That's not much of a ride window he suggested.
I understand your post but have no idea what CSN ?
That's probably more obscure than trying to resolve ridge's posts.
Somehow CSN went over my head as do many acronyms. Now if you had said CSNY, that would have rung a bell. Don't ask me why?Lol, OMG, WTF. CSN Crosby, Stills, Nash. I assumed knowing the age of so many cyclist in every club I've ever joined, somebody would catch the reference.
