GG to BW
My husband and I have done the GG to BW from the beginning. The first year when there was not enough snow to do the whole route, we did the 25km untimed. Then we graduated up to the 50km and have been doing it ever since... We wouldn't miss it, although as Ryan (jokingly!) says, I wouldn't recommend it, but somehow we keep doing it every year!
It's really the climb up Jefferson Notch Road (9km) that is the toughest... the first 29km are a mix of terrain, and the last 12km are mostly downhill, but the slog uphill tends to tax me a bit... My finish has never been under 5 hours, but Ryan tends to finish around 4 hours.
For us, it's a great motivator to make us get out as often as we can through the winter and ski, and keep in shape in general. Plus, although there are times while I'm out there that I wonder what the heck I'm doing, I am always very satisfied with myself when we're done. I mean, hey, how many people ski in a 50km ski race with a huge 2000ft climb in the middle?! As for the timed vs. untimed thing... the first year we did the 50km option I did the untimed thing, but I found myself really wanting to know where I came in in the crowds, and decided that part of the accomplishment for me was knowing how much I could improve from year to year and seeing where I compared to others. I say I'm not competitive, but I guess I am
All in all, I would say it's a great event, very well-run and well-manned at the food stations with a great awards ceremony, and there is a great range of people who ski it, from the super fast people (how do they do it?!) to complete families (I think the best is the family that ranges from young kids up to their grandfather in his 80s who has skiied the 25km for the past few years). It can be competitive if you want it to be, but otherwise it can just be a great excuse to get out and challenge yourself!
Hope to see you out there!
