I ' m kinda chuckling at bearable being applied to the NYC Marathon . It was in the mid 50 s this year . I ran in a shortsleeved tech shirt and capris ! It was really optimal and I know I ' m lucky , but since 2000 , the average high for the race day has been 57 degrees . In general , you need less clothing than you might think to keep yourself warm while running since you are generating so much heat . Last year was my first fall of running , and I used Dress My Run to help me figure out what to wear . You don ' t need much gear for cold weather . The long sleeve and short sleeve tech shirts you usually wear can be great base layers , then you just add an outer layer and some coldweather accessories and you ' re good to go . Generally , I like clothes that are slightly adaptable so that I can make adjustments as I warm up during my runs . The Saucony U l t i M i t t g l ovesunisexsauconyultimitt 530044 sa 90508 . html is great ! I have a jacket that zips all the way for ventilation and it ' s got pockets , so that I can stuff in gloves or hats after a mile or two . My jacket and hoodie also have not just thumb holes , but also an additional little flap that can cover my entire hands to keep them warm . I have no idea what these are called and I tried to find an example but I can ' t . I have a pair of Sugoi tights , but a lot of times I ' ll wear capris and maybe crew socks if it ' s slightly chillier . I don ' t have special shoes for the winter , but if it ' s rainy or snowy , I ' ll definitely wear merino wool socks . As you ' re getting used to training outside for the half in the cold , you ' ll probably find that winter NYC temperatures won ' t really inhibit your performance in a very noticeable way . Most of the time , the winter weather here is optimalor close to itfor running . It ' s the summer training for the marathon that ' s gonna get you .
