back to swimming. i looked up my salt water pool. it says it is a mixture of salt and chlorinated water. it is outdoors and is heated to 28 deg C and is 25m long. so 40 lengths would be a kilometre. i dont know how far people who swim in pools swim? but maybe i could do an hour or less a week. not much else to do there as it is only 1.4m deep at the deepest bit. since it is outdoors, i would be forced to do half on my front and half on my back to make sure i didnt get an uneven tan lol there is also the inlet near me which i am going to scope out for the summer hols as that really is salt water and the kids can play there. project for the summer exercisewise is try to do more swimming!
