I've run the NYC Marathon every year for the past 4 years.
Unfortunately, I didn't get in this year, but I plan to volunteer as an
interpreter. The following impressions are from memory, so some
distances are approximate.
The weather varies. I understand the temperature this year is expected to
be about 55 Fahrenheit.
The course starts on the bridge that links Staten Island to Brooklyn. We
then run about 13 miles through Brooklyn, to a bridge that links Brooklyn
to Queens. The crowd support in Brooklyn is tremendous. However, the
first few miles are quite slow. You might not settle into your pace until
4 or 5 mile mark.
We run a few miles in Queens. There is a nice table of food, coffee,
Gatorade, and other treats provided by one of the local running clubs. Then
comes a long, crowded, uphill bridge into Manhattan.
We hit Manhattan at about the 17-mile mark. Again, tremendous crowds.
We run through the cheering crowd for about 2-3 miles, up First Avenue to a
bridge that links Manhattan to the Bronx.
The Bronx is largely deserted. We almost immediately run across another
bridge back into upper Manhattan. The next mile or two are quite tough,
until we hit Central Park at the 23-mile mark. We run up a short, steep
hill, and then run the remainder of the race through the ecstatic crowds
in hilly Central Park.
It's a great race.
