The big draw is a 26-mile run through the Inner Harbor, Federal Hill, Fells Point and a handful of other scenic neighborhoods (including the zoo!), but if you’re not up for that much of a race, there’s also a half-marathon, a 5K and a Team Relay, even .1- and .2-mile Fun Runs, for kids 12 and under. There’s no charge for standing along the course and cheering on the runners. The marathon and the Team Relay start at 8 a.m. Saturday at Paca and Camden streets, with the 5K starting a half-hour earlier and the half-marathon at 9:45 a.m., both at Light and Pratt streets. Start times for the Fun Run are 9:20 a.m. and 9:30 a.m. at Rash Field, 201 Key Highway. The cost to run ranges from $20 for the Fun Run to $280 for the Team Relay. thebaltimoremarathon.com.
