The Rock N Stroll 5K Fun Run/Walk kicks off at Broadway and Main Streets at 9 a.m. Saturday, May 29. Registration is on the North Shore River Walk under the Broadway Bridge. Advance registration is $30 for adults and $10 for children 10 and under. Registration on the day of the event is $35 for adults and the same for children. Participants receive Riverfest passes and a T-shirt for entering.

In addition to hosting one of Riverfest’s main stages, the Clinton Center is offering a number of special deals throughout the weekend. Since the center’s normal parking area will be cordoned off for Riverfest, Thursday through Sunday visitors should park at Verizon Arena (for free) and ride a shuttle. On Saturday and Sunday, admission to the library is $2 off. Forty Two, the library’s on-site restaurant, is also offering 10% off for diners who pay with Riverfest “River Bucks.” From 10 a.m. to 2 p.m. on Saturday, the center hosts “Build My Pins,” where local artists will work with kids to make decorative pins that, like those in the Madeleine Albright collection on display through June 1, send a message.
