  The Thousand Island Park 5K, or TIP5K, is a memorial footrace to honor the memory of General TJ "Demon" Costello, who served as a fighter pilot in the United States Air Force. This race started at a family reunion in 2013 and has grown to include the local community of TI Park. It's a small, family-oriented race that welcomes all levels of participation. Walkers and strollers are welcomed! Although, be advised that the course covers dirt roads, grassy lawns, and one trail. Also, the route will be poorly marked, open to traffic, and the timing crew will consist of a couple of teenagers with an iPhone. No timing chips here! So, your official time will likely be wrong, if it's recorded at all. However, I can guarantee a great scenic run, good times and camaraderie, and maybe a cold drink or two at the finish line.
