Get ready for a spooky nighttime adventure on the Lawrence River Trails, where you can tackle either a 5K or 10K after sunset at 6:30 PM with some creepy surprises waiting for you along the way. Make sure to pack a headlamp, waistlight, or flashlight to light your path, and while costumes are totally encouraged, remember that you'll be running on trail terrain in the dark so choose wisely. The good news is the Lawrence River Trails offer a relatively flat course, though keep an eye out for staggered start times between the two distances closer to race day.
