Productive time in London but the downside was little to no sleep and last night was no different. I woke up around 4:30am and did some emails until about 5:30am. Was considering going back to bed but decided to venture out for a run. The mission was to run down to Fulham's Craven Cottage and back. Not a very speedy run but I was still feeling good about it until the 3 mile mark when my calf started giving me trouble. It knotted up and hurt all the way down my Achilles. Thankfully I was close to the hotel and limped back the last half a mile.
