No snow over here in Korea (at least where I live). Just cold. So scratch cross-country skiing. Swimming is a great idea but I swim like a beer bottle as they say in Korea. A good reason to practise I suppose. I still get into the gym for weight training twice a week and run once or twice a week but I really need the aerobic rides of at least 1 1/2 hours per session at least 3 times a week.
