I think the change of seasons is very good for runners. In the colder weather, your body is able to train faster (its not encumbered by heat induced diminished performance). During the warmer seasons your body learns to perform and acclimates to warm temperatures. Heat dissipation improves.
In CNY the hilly terrain may be an additional positive factor.
That is totally idiotic. Performance is hindered in cold temperatures. Ideal distance temps are no lower than about 38 degrees at the absolute coldest. We are talking about subzero temperatures in the winter here, not a cool day in Seattle.
This is what the research says:
"When French researchers analyzed the finishing times of 1.8 million marathoners over a 10-year period, they found that a race-day temp of 43.2Â°F produced the quickest times overall. But faster runners, who generate more heat, benefited from cooler temps, with the top one percent (green line below) peaking at 38.9Â°F. Midpackers (red line) do best in the mid-40s.
The reason seems simple: all else (e.g. body size) being equal, metabolic heat production is proportional to VO2, and VO2 is proportional to running speed. A marathoner running 2:05 is consuming more than twice as much oxygen as a 4:00 marathoner, and thus generating more than twice as much heat -- so of course you'd expect the faster runner to prefer a cooler day."
Syracuse has a greater proportion of its days closer to the range than many other areas of the country. Yes the winter temperatures months are colder than that but you have to look at temperatures for the whole year.
