Do you downhill snow ski? If so, perhaps do something you can't do at home. South Lake Tahoe has the Heavenly ski area that is quite nice, among the best in the USA. I would not go if zero ski experience, it would be a waste to just run the beginner bunny hills. But if you ski, rent equipment at the hill and have a grand day. Not cheap per day for lift ticket and gear rental, but an especially good time. On top of the mountain will have a bit of altitude acclimation, but not bad if you are in shape from biking. I think the closest major airport is Reno NV. Driving from San Francisco or Sacramento CA is longer, and you'd need to make sure they put tire chains in the trunk in case you need them, going over the mountain pass to South Lake Tahoe.
