weather on the cape today was unseasonably cool and dry - temps in the lower 60s and humidity in the 50-60% range, with a nice stiff breeze from the northeast. so a good day to try out the rail trail. the course was scenic and very easy to follow, and despite a late start it didn't really get crowded until the last 8 miles or so (mostly bikers). mileage came out to 26.8 so basically this is a somewhat flat road marathon with a bit extra on the ends for warmup/cooldown.
i ran unsupported with 2L of tailwind - probably didn't need that much but i didn't see any potable water sources along the route and prior runners had mentioned all the water spigots were off due to covid. considered running dry but wasn't brave enough. i saw about 10 ice cream shops along the route so i guess that's an option if you want to go supported and can stomach it...
