Hey there! This is a little of a drive from the NS, but I'll put it out there anyway.
The Empire State Winter Games now have a winter bike race event. There's three races: XC, Enduro, and Bike Cross (like ski and boarder cross but on bikes). The event takes place at Mount Pisgah Ski Center in Saranac Lake, NY.
Here's the link.
It's a new event and open to anyone. Come race or at least help spread the word!
See you on the trail!
