The Morton Arboretum is debuting its first-ever endurance challenge in May during National Physical Fitness and Sports Month. The Firefly Race Series starts on May 3 with a 3K fun run and walk at sunset, followed by a post-race glow party. The challenge continues on May 4 with a 10K race along a USATF-certified course through the Arboretum’s rolling terrain.

“This is the Arboretum’s first endurance challenge and one of the few two-day race series hosted in Illinois,” said Arboretum Special Event Planner Kate Fitzgerald. “The 3K is an approachable race for beginners, and a great warm-up to the more challenging 10K course for more seasoned competitors and those training for half or full marathons.”

The 3K sunset run and walk at 7:30 p.m. is an after-hours Arboretum experience that concludes with a neon-themed, deejayed post-race party under the stars, with snacks and refreshments from local establishments Bubblehouse Brewing and Go Brewing. The 10K race at 8 a.m. winds through woodlands, marshes, lakes, prairie and ornamental tree collections famous for their floral displays.

Registration includes Arboretum admission, a Firefly Race Series finisher sticker for all finishers, a neon quarter-zip pullover for the 10K and a long-sleeve T-shirt for the 3K, and a free alcoholic or nonalcoholic beverage from Bubblehouse Brewing or Go Brewing.

Cost: 3K is $50 for members and $55 for guests; 10K is $60 for members and $65 for guests. Registration for both races is discounted at $95 for members and $105 for guests through April 23. Virtual participation options are also available at $40 for members and $45 for guests for the 3K; $50 for members and $55 for guests for the 10K; and discounted through April 23 at $80 for members and $90 for guests for both races.
