Standard water locations:
The 424 8 mile water stop is traditionally just a bit past the entrance to the Crofton Park on the right side of the road, off the sidewalk about 8 feet, and slightly BEFORE the 8 mile mark on the road.
The 10 mile marker on Reidel road is slightly past the golf course, on the right side of the road just off the sidewalk.
Most of the time there is also water at 596 Pinedale Drive (near the top/end of Pinedale), which is a left turn after you turn onto South Haven from Truman Parkway, and just after you pass under the bridge that is Highway 50. Pinedale is one mile in and one mile out. I keep water there most Saturdays if you ever want to use this for some extra mileage on a fairly quiet street with some good hills, and where you can easily manage the road slant by going to either side of the road. Water here is on the right hand side by the blue mailbox.
