4 Mile Run - North End to Charlestown & Back

Got out the door this evening as the sun was setting for a planned 4 mile run from the North End, into Charlestown and back. I programmed the Nike + Ipod for 4 miles and began my trek through the North End towards the bridge. I stretched near the good ol' Italian bocce courts then ran across the bridge, into Charlestown, along the water, past the USS Constitution, past the Naval Base, around the new high rise construction down on 5th st, before looping back. The run is here: http://tinyurl.com/hhqvo. I finished the 4.01 mile run in 31:56 for an average pace of 7:57 per mile with 540 calories.
