From my exeperience, you can actually go faster at 40 degrees, since you don't need to waste energy cooling off. However, this requires that you either take off one or two layers after warming up, or dressing lightly enough so that you're pretty chilly until you warm up. This varies greatly from person to person, but in general people tend to overdress in cold weather. The trick to cold weather is to remove layers before you get sweaty. _ Booker C.

If you wear tops with zippers, and headbands, the ability to expose more or less flesh in the critical areas of the neck, throat, chest, and head will make all the difference.

om... I'm OK riding in the colder weather, but it never ceases to amaze me how much more work it seems to be to make the bike go once it gets below 40 degrees. Just don't tell me it's mostly got to do with the density of the air... It takes much more effort for me to get warmed up, but in the end I feel stronger in the cold even as low as the 20's. In the cool to hot temps I have problems staying hydrated. I'm really happy that temps are coming down. Dave |

FWIW my personal experience is that I ride fastest and easiest when the temperature is between 80 and 90F. I'd probably be a happy guy living in New Mexico or Arizona, as I like it hot. Here in Minnesota there are only about six weeks of good warm weather a year, and 6 1/2 months of generally OK weather- and four months of generally annoying weather, at least from the cycling perspective. Sadly they've not been good months for cross-country skiing or snowshoeing for most of the past 10 years However, this requires that you either take off one or two layers after warming up, or dressing lightly enough so that you're pretty chilly until you warm up.

I'd agree with the practice you describe, as a way to prevent initial overheating and then getting cold when the insulation provided by your clothing is compromise by moisture, but not the underlying reason you propose. |

Based on what I've read: When it's hot, more blood is directed to the surface of the body, leaving less for the leg muscles. Because of this, heart rate increases about 1 beat for every degree above 75F. -- terry morse Palo Alto, CA http://bike.terrymorse.com/ |
