Wisconsin Trail Assail National Watermelon Day Run Hartford, WI   Aug 1, 2026

Did you know the world record length for spitting a watermelon seed is 75 feet 2 inches? Did you know the world’s heaviest watermelon weighed in at 350.5 lbs! Did you know the record for most watermelons crushed with a persons head in one minute is 43? Did you know, that the National Watermelon Day race at Pike Lake is one of the most spectacular and challenging trail races in Wisconsin? Well, now you know the facts.

Come join an amazing trail run/walk at Pike Lake, and yes, of course, there will be watermelon! Pike Lake is a technical course with roots, ruts, rocks and a couple “rolling” hills. Ok, it’s one of the most challenging courses in the Wisconsin Trail Assail Series. The 5K course is long. Also note that GPS watches vary greatly on this course. We have measured it with multiple devices many time and it can vary up to 1/2 mile on the half marathon course. Check out the free, fresh fruit, finish line aid station. Sure beats stale bagels and green bananas!
