It seems a better choice to go for a 4 mile run around here as it'll end up being longer than a targeted 5-miler. Street signs would help a great deal! Stay tuned for how tomorrow's marathon course run turns out. Plenty of pre-planning has gone into creating a map, logistics to arrive, along with backup options.
This morning's easy 5 miler time of 74 mins includes stops and walkabout golf club (discovered members only) that also has tennis and swimming. Best establishment I have seen in the area.
