I ran the manhattan perimeter loop. The time was 4:09:46 as shown on my strava but there was a gps glitch on the map so I did a brief extra run to add that extra bit to make sure my effort counted in case the map glitch matters even though it adds a couple minutes to my time. [Note: The gap between the start and end points on Lisa's GPS track is about 20m, so not significant.]
I ran with a hydration vest and my own gels and snacks. Friends and family filled my bottles along the way and gave me more snacks, so it was supported.
