Need a new ride?
From 10 a.m.-4 p.m. this Saturday, check out the Fall Brooklyn Bike Jumble at Old Stone House/Washington Park, (336 3rd St., Brooklyn). New and used wheels for adults and kids will be on sale at this bike-themed flea market, and biking nonprofits and frame-builders will be there, too.
Exercise for a cause
The 22st Annual Komen Greater New York City Race for the Cure is a 5K taking place this Sunday in Central Park. Visit www.komennyc.org for more info.
Pure Barre, the insanely difficult ballet-inspired workout that city-dwellers flock to in droves, has opened a second location in Union Square (78 5th Ave., 4th floor). New to class? The new student special offers a month of unlimited classes for $150. Check out www.purebarre.com for more info.
Fitness to boot
Interested in getting in on the boot camp craze, but not ready to make a six-week commitment? Tim Haft, who we've written about before as the face behind the Greenpoint 5K training group and the city's Punk Rope gym classes, is offering a free trial class of his Beastanetics interval training program today and tomorrow, at 6:45 a.m., 8 a.m. or 9:15 a.m. in Williamsburg's McCarren Park soccer field. Like what you try? The full six-week series starts next week. Visit http://punkrope.myshopify

Get outside while you still can
Head to Wanderlust Yoga in the City, an urban retreat being held this Sunday (1-6 p.m.) at Hudson River Park's Pier 63 Lawn, for gratis yoga classes led by some of the industry's biggest stars. There will also be fitness and nutrition seminars with Health magazine editors and skin care samples from Elizabeth Arden. Registration is free, but you have the option to donate to Yoga Aid World Challenge when you sign up, which supports charities that espouse the teachings of yoga.
