OK....my trip to Gunnison, Co. started out to be a road biking only deal but now I have decided to take the mountain bike for sure. I've looked at as many videos as I can find on the various trails around CB and 401 looks like THE one to do. I would call myself an intermediate-beginner as far as technical skills are concerned and there are about 3-4 little spots in the ride that look like they would give me problems unless I can get off and walk a little. At 65 I'm not old enough to know better but I'm also old enough to not press my limitations! These places look to be about half way around and they look like rivulets that have washed out and appear to be fairly narrow and possibly a little slippery to walk or ride. So, y'all tell me EVERYTHING you know about 401 and what I need to be aware of before heading out on a single track that doesn't allow for a bail out! Thanks again in advance for any help!
