We do love being active here in Wales. Rugby is the national religion, and we have proven time after time that the best way to deal with the excesses of a Saturday night is to get a good sweat on come Sunday morning. Well, maybe after the greasy breakfast, but that just provides more fuel for the fun. High-octane adrenaline activities, relaxing strolls or some good old-fashioned elite sport — there is plenty to do in Cardiff.
