Race morning at 7am sees a chill in the air with temperatures averaging around 15.1°C and a slight chance of rain—about 1mm expected—with the trail feeling firm yet slightly soft underfoot, creating an invigorating atmosphere. The park's natural beauty enhances the experience as runners traverse through wooded paths and open meadows.
This event has been running since its inception in 2023, attracting over a hundred participants each year who come to support brain research initiatives led by The Brain Foundation. With both adult distances of 5k and 10k alongside virtual options that include medals or shirts for an added incentive, the race offers something for everyone.
The course venue is Burke Lake Park, featuring firm yet slightly soft trails that are well-marked throughout its layout. Participants can expect to start their journey from the park's main entrance on Little River Turnpike near the intersection with Lee Highway. The 10k route includes more expansive stretches while the 5k offers a shorter but equally scenic course.
