Luckily there is a train between the two but my Wk8 R2 was in the early hours and included a run down 5th Avenue, around the Empire State building and through the most polluted streets I've run in, but with amazingly tolerant pedestrians and taxis who stop to let you run across the avenues. The excitement of knowing you are running around such an iconic city takes the pain away and the 28 minutes fly past.
Just did Wk8 R3 this morning, from Capitol Hill to the White House and around in several confusing circles until I found my way back to the rented condo - much tougher to run here in Washington than in NYC as traffic was heavy and it involved lots of running on the spot waiting for lights to change, but again the amazing views took the pain of the first 20 minutes away - the last 8 were hell, out in the boring suburbs and no great views to ease the leg cramps and ankle pain from uneven sidewalks.
But who cares? I'm done, and Friday I go into Wk9, and then fly home to complete the last two runs around Harrow park - not quite so glam but its progress.
