PB&J Fuel Run 5K/10K/13.1 DENVER/AURORA

The PB&J Fuel Run 5K/10K/13.1 DENVER/AURORA returns to Aurora, Colorado on October 31st. The event offers a variety of distances including the popular 5K and 10K runs alongside a half-marathon option for those aiming for an extra challenge or distance. Participants can also join in the Family Fun Run covering just one mile.
Race morning finds participants gathering at Aurora Municipal Park, situated along East Colfax Avenue near downtown Aurora. The atmosphere is laid-back with smooth vibes and sweet energy, perfect for runners of all paces and ages who are looking to enjoy a stress-free run or walk alongside friends and family. This event has been running since 2015, supporting local community initiatives through its participation fees.
The course venue offers a mix of paved paths and well-maintained trails within Aurora Municipal Park. Runners will start from the park’s main entrance, wind their way through lush greenery, and finish back at the same spot. There are no timing chips required—participants can track their times using personal devices or let coordinators assist them if preferred.
Weather on race day typically ranges between 6 to 21 degrees Celsius, with an average of about 44% humidity. The wind is usually light but could be a factor for those running in the early morning hours when temperatures are cooler. Precipitation risk is minimal given the dry autumn weather conditions expected in Aurora.

The PB&J Fuel Run offers five distances: the 10K, 5K, Family Fun Run (1 mile), Half-Marathon (21km), and a Virtual option for those who cannot make it to the race location.
