The Next Loop Endurance Series - Busse Woods

The Next Loop Endurance Series at Busse Woods takes place on August 15, 2026, within Ned Brown Forest Preserve in Elk Grove Village, Illinois. The course uses a clearly marked 3.1 mile (5K) loop that returns each lap to a centralized start/finish area with a fully stocked aid station.

The trail winds through mature woodlands, open meadows, lakeside sections, and shaded forest canopy. The surface is primarily smooth crushed limestone and packed gravel with occasional paved connector sections. Terrain is mostly flat and non-technical, providing steady footing for repeated laps in a variety of conditions.

Distances offered include multiple loop totals, allowing participants to accumulate distance over time. Available distances:

• 5K
• 10K
• 15K
• 1/2 Marathon (13.1M)
• 18K
• Marathon (26.2)
• 50K

The event format has athletes start together and complete one 5K loop at a time. Participants may choose to continue after each loop; every completed loop is recorded and honored, and there are no mandatory cutoffs tied to distance. The site sits near the Chicago metro area and is noted for surrounding lakes, wildlife, and forest preserve views. Visit the organization's website for the most recent information.
