Approximately 50,000 runners will participate in the New York City Marathon on Sunday, and like last year, they'll be treated to a high level of security.

According to CBS 2, organizers say procedures will be much like they were last year—bags will be checked, family members at the finish line and reunion area will be screened, bomb-sniffing dogs will be on hand and entrance and exit points around Central Park will be sealed, just like they were in 2013, post-Boston Marathon bombing.

There's some more new stuff this year, too, like giant Jumbotrons along the route and amped up tracking technology. This year's marathon is expected to usher in the one millionth finisher, and that lucky runner will be guaranteed entry for the rest of his or her life, a solid deal provided he or she is one of those maniacal serial marathoners.

It's also noteworthy, as reported earlier this month, that this marathon boasts far fewer charity runners than in previous years. According to the Wall Street Journal, some charities had trouble finding enough fundraisers since New York Road Runners guaranteed entry in 2013, 2014 or 2015 to all runners who were shunted by the post-Sandy race cancellation, regardless of whether or not they were able to raise money. Fewer organizations signed up for the marathon this year, and a number of them offered fewer slots for runners.

The marathon also has a refund policy and beefed up insurance in the wake of the Hurricane Sandy cancellation. NYRR reportedly lost $4 million that year thanks to refunds shelled out to runners and sponsors. "We now have a refund policy, and we have a lot of insurance,” Mary Wittenberg, chief executive of NYRR, told Crain's New York. “The good thing that came out of Sandy is that it was clarifying for us."

And for those New Yorkers/elected officials who are wracked with Ebola paranoia, the NYRR says no runners from the three Ebola-ravaged West African nations, Sierra Leone, Guinea and Liberia, are signed up this year.

The marathon kicks off in Staten Island early Sunday morning. Keep your eyes peeled for Bill Murray.
