In 2013, i did the New Jersey 600k thinking they always did the easy route through the pine barrens. It turned out that ride was the route through the catskills, which is very climby. One feature of that ride was a group intervention with a rider that was going to dnf with less than 20 miles to go (and very little climbing left). I was thinking about doing their 600k this year and hoping they do the pine barrens route. But I might end up with DC or Eastern PA instead.
I think iTrod and I will do the Million Meters of Chocolate Milk 1000k
