I am going to ride from West Yellowstone Montana to Grand Tetons Wyoming in mid to late Feb 2015, anyone know how many miles?

Coming up again next week for a ride and want to go from Amos to Matagami. Just woundering how fast that trail is, i know its about 200k but how many hours is it. Hoping to go from Rouyn to Matagami in a day. What are the conditions like, here there is a ton of snow. any input is great cheers
