Yes, it is Cyclocross season and I have been training. But that's not what I am referring to. It's almost fall and after that winter. What happens in fall and winter? It gets colder? Yes of course. But more importantly, the angle of rotation of the earth with respect to the sun changes which effects how directly the rays of the sun strike the earth in North America. This causes colder temps for sure. But it also causes shorter days, more darkness and in the daylight that we do have, the rays of the sun strike the earth at a more acute angel. The results? Reduced UV B rays which our bodies use to synthesize vitamin D. It has become exceedingly clear in the past few years that this has profound effects on our health. The more north you live, the greater the effect. Reduced vitamin D synthesis causing deficiencies. These deficiencies make you more vulnerable to colds and flu. And long term, cancer and other diseases.

As a cyclist, your power output will be reduced, not just because of less ride time but because your muscle mass and other physical capabilities are reduced due to vitamin D deficiencies. What to do?
