I did the full Montauk Century last year. It was great, the weather was perfect. It was my first century ride.
I "might" be riding it again this year. My girlfriend had a minor surgical procedure last week so she is not sure if she will be ready to ride it. Since there is another Montauk Century two weeks later, June 2nd we might ride that only if my friend feels that she cannot ride the first one.
I will keep you posted if I ride it, you never know who you pass or meet up at the rest areas or even the dinner at the end
