Stretching out the distance

There are two weekends before my marathon on October 13 and I am running other races or have other plans.  So, I have to do my long runs during the week.  It was 90 something this afternoon, but I went out to the park and ran 2 miles on the park roads and 14 miles on the trails, for a total of 16.  Luckily, my knee held up okay.  I found 2 lost and dehydrated ladies in the back of the park.  I gave them directions and part of my water.  I barely had enough to get back to my truck and replenish before running another loop.  I assume that they made it back okay.
