On the island running front

I've been building up my distance lately as marathon day (or M-day) draws closer. Last Sunday I had a beautiful 10 miler out to the ocean and back, which you can see here on my map of my running route. I'll keep adding to this as my weekend runs lengthen. For my 20 miler, I'm thinking about going out to Siasconset, around to Polpis and back home. And maybe if I go totally insane, I'll run out to Great Point and back. But that seems unlikely.
