  Join us for our annual 5K Walk-A-Thon in support of adolescent physical and mental wellness. This event helps raise funds for our 4-week summer camp serving students in 3rd through 8th grade. More than a summer program, this camp is designed to be a safe, active, and encouraging space for youth during the summer months.

  Led by a longtime Maywood District 89 educator with more than 30 years of service, this initiative is rooted in the belief that adolescents need safe spaces, positive structure, and opportunities to stay active for their overall health and well-being.

  August 23, 2026

  7:30 Start

  The Summer Trail Classic is the third of four events of the 2026 Dick Pond Athletics Darn Tough Trail Race Series.

  After galloping over the wide crushed limestone lanes at Chauncey’s in April and overcoming the hills on the wide grass/dirt pathways of Hickory Knolls in June, we are now venturing onto the twisting and turning single-track trails of Paul Douglas Forest Preserve in Hoffman Estates.

  Choose from three different distances – approximate 4 miles / 9.5 miles / 13 miles – for a true trail running experience!

  Date: August 23, 2026

  Start Time: 7:30am (all distances)

  Distances:

  Approximate 4 miles / 9.5 miles / 13 miles

  Walking-only participants are only allowed in the 4 mile distance, and support on all three courses will be removed at 12:00 Noon.

  Location: Paul Douglas Forest Preserve, Central Avenue (just west of Roselle Rd, and just east of Barrington Rd), Hoffman Estates

  Sponsors: Dick Pond Athletics, Mount to Coast and Darn Tough

  Beneficiary: Chicago Area Mountain Bikers (CAMBr)

  CAMBr is the Chicago Area Mountain Bikers, a volunteer organization of hundreds of riders who work to ensure that mountain bikers have diverse and challenging local opportunities to enjoy their sport. Our members have donated thousands of work hours to build and improve area trails.

  The mission of the Chicago Area Mountain Bikers is to educate bicyclists, promote responsible trail use, prevent trail closings, maintain and build multi-use natural surface singletrack and freeride cycling opportunities in the Chicago area. CAMBr seeks to promote trail and freeride bicycling through stewardship, environmental and social responsibility, education, and a spirit of cooperation among all trail users, the conservation community, and governing bodies.

  Please visit cambr.org if you are interested in finding out how you can get involved with CAMBr’s trail maintenance activities and/or cycling events.

  IMPORTANT: The Forest Preserve has very strict regulations in place regarding the trail use at Paul Douglas – if the trails are WET, the trails are CLOSED. If there is significant rain in the days immediately before race day and the Forest Preserve office deems the trails are not usable, we will shift the race to the asphalt bike path at the preserve. You will receive an email from us no later than Friday evening, August 21, notifying you of the change to the bike path with details about the course and race distances.
