Boston Marathon Tips

Hi! I just ran the Marine Corps Marathon this past weekend and joined my first Endorphins shakeout run. I’m excited to start joining the Boston runs with you all. This was my first marathon and I found out last night that I got a bib for Boston this year. I have never run in the winter and I’m a big skier and am feeling very intimidated by the winter training. Does anyone have any tips for keeping up with training in the cold/snow? Or tips for being able to ski and get long runs in? Thanks!
