 With temperatures projected to make a dramatic increase in this week's forecast, runners around Boston have to deal with different obstacles, including melting snow. We spoke with Boston University's professor and an athletic trainer to discuss how the changing weather will affect their exercise daily routines. This is called a climatization where your body kind of gets used to being in different temperatures, whether it's cold or warm. And so when you go from really cold to really warm in a quick period of time, you can have some people have some troubles with dehydration and overheating and those types of things, so making sure that you're well hydrated, making sure that you're really paying attention to how long you're participating for and trying to do it in the cooler parts of the day actually is a better idea than going out in the high point of the afternoon when it's really starting to get warm. We caught up with local runners on one of Boston's most popular routes to hear their perspective on running during New England's unpredictable weather changes and the upcoming heat wave. So I will hydrate more. I also, you dress with shorts and a t-shirt or a loose running shirt and you bring water with you. Usually I don't when I run in the cold weather, but when it gets really hot you get dehydrated and you need to have some fluids. I mean, I guess it's just like pulling out some of my spring gear and running in that a little earlier than I anticipated. Take a few more stretching measures before leaving and then just like definitely layer a lot. We are here today at the Esplanade where Boston Hunters are excited to be back on their track after temperatures are supposed to get up into the 60s at the end of this week. Runners have to prepare their bodies differently because hydration is a key factor in making sure they're okay on their run. The Groundhog may have predicted six more weeks of winter, but the spring in New England seems to be coming early. For BUTV News at Noon, I'm Rachel Blauner.
