A memorial event paid tribute to first responders who died in the 2001 attacks. Participants climbed over 2,000 steps, equivalent to 110 flights of stairs. The climb was organized to honor the sacrifice of those who lost their lives.

Organizers noted that this year's event was particularly challenging due to the heat. Despite the conditions, hundreds of people took part in the climb.

Further details about the event are available from the source, including comments from a firefighter who has organized the climb in previous years.
