Ok you're off the deep end. Just ride. When it rains lube more often. Always wipe excess off. The chain may not last the trip or exceed the trip entirely according to the conditions on the trip. 500miles of grit and mud could equal 3000 miles of dry riding. If you measure a stretched chain replace it but replacing a chain "whether it needs it or not" makes as much sense as replacing your bike, whether you need it or not.
