Arlington's warming weather signals it's time for fun under the sun, with Arlington Parks and Recreation throwing a bash to mark its centennial year – a 100-mile walking, running, and biking challenge that everyone's invited to punch their card in, starting May 3. This all-in Arlington Parks Centennial x TREK 100 Mile Challenge, with a kick-off shindig set for the lush environs of River Legacy Park's Elm Grove Pavilion, aims to rev up locals with grub and good vibes, according to the City of Arlington, Texas.

Frolics aside, those with a taste for tradition can savor a slice of cultural celebration at the Cinco de Mayo event tailored for the 50 and older crowd, rolling out the welcome mat on the same day at Dottie Lynn Recreation Center, with gratis entry to boot. On May 4, in a nod to the stressed and overworked, the folks at East Library and Recreation Center are doling out root beer floats alongside puppy cuddles - a quirky, sweet remedy for life's pressures.

For those looking to honor the maternal figures in their lives, Ventana Grille at Tierra Verde Golf Club dishes out a Mother's Day Brunch on May 12, with the kids getting their fill on the house if they're three or under, older guests footing a bill of $50 or half that for children aged 4-12. And for those eager to swing for the fences, Arlington Parks saves a homer with a Home Run Derby, slated for May 23 at Randol Mill Park's Green and Yellow Fields.

A century of community recreation is quite a milestone. It calls for a toast or perhaps, a well-swung bat for those inclined. With food trucks, booze, and music in the queue for the Derby, it seems like Arlington Parks knows just how to party – only the strongest slugger will take home the crown and the windfall with it. All the while, the usual suspects of vendors, yard games, and giveaways keep the ball rolling in the park's honor.
