Luckily the weather ended up being not too hot (until the last couple miles) and the trails were not very muddy. I carried about 14 SiS energy and two filter bottles. I refilled my water at the stream at ~5.5mi, the spigot at the Washington Monument, and the spigot at Gathland State Park. I don't know if there is a spigot in Harper's Ferry but if there is then I highly recommend filling up there if you make this attempt. Even though you only have a few miles to go after Harper's Ferry those miles are almost all uphill and hard with some exposure. I lost a lot of time in those miles but with enough food onboard and a water refill that could have been avoided.
I am very happy to get the FKT! Hopefully someone can go and knock it down a bit more soon... good luck!!!!
