Walking challenge - we can still make it!

When we started our walking challenge we thought that 400 miles for the four of us in two months, April 1st was the target date, would easily be doable. Then the treadmill broke and our challenge hit a snow bank so to speak. Yesterday it was finally nice enough to take a walk outside so we added a few miles to our total. Looking at our numbers we figured out that we can still make our goal of 400 miles. We have 341 miles to go meaning that together we need to only walk 48.5 miles per day or 12.1 each. Just don't see that happening.
