Kick off the winter running season with River City Races' Polar Bear Grand Prix, an invigorating series of races designed to keep runners motivated through the chilly months. The first leg of this year's grand prix takes place on December 10th at Cherokee Park in Louisville, offering a scenic four-kilometer (2.4 miles) run and walk along the park’s picturesque Scenic Loop. This race is not just about hitting your stride; it’s an opportunity to embrace the festive spirit with fun challenges like the costume contest and Rudolph photo ops. Participants can look forward to age group awards, overall male and female winners, as well as masters and grandmasters categories. Each finisher will receive a commemorative medal that fits into the larger Polar Bear Grand Prix series finale. The entry fee includes a long-sleeve race shirt, free photography services with Rudolph, and access to post-race photos for sharing your memorable moments online or on social media platforms. For those who prefer the comfort of their homes, there's also an option to participate virtually from anywhere in the world. In addition to individual accolades, teams can join the Polar Bear Grand Prix Team Challenge across all three races in December, January, and February. This team event is open to 3-5 person groups in male, female, or coed divisions, with each winning squad receiving a special award for their efforts. The challenge adds an extra layer of excitement as teams compete not only against other participants but also within themselves. For those who wish to give back while enjoying the race, River City Races has partnered with the Olmsted Parks Conservancy. Participants can opt to donate or fundraise during registration; raising $150 or more will waive your entry fee entirely and contribute significantly towards maintaining Louisville’s renowned park system. Whether you're a solo runner looking for a spirited start to winter training or part of a team aiming for glory, the Reindeer Romp is set to deliver an unforgettable experience. Don't miss out on this chance to celebrate the season in style while supporting local parks and communities. Join us at Cherokee Park as we usher in the running/walking season with warmth and camaraderie.
