Run for Resilience is a community walk/run in London, Ontario, held in Springbank Park in October.

All routes stay inside the park, keeping the event contained and easy to follow. Runners, walkers, families, and supporters share the same event day, with a focus on participation at every pace. The race also raises support for accessible mental health care for neurodivergent individuals, giving the distances a purpose beyond finishing.

Tails on Trails is a dog-friendly charity trail race at Bechtel Park in Waterloo, run in late spring and hosted by Run Waterloo with the Humane Society of Kitchener Waterloo & Stratford Perth. Runners can choose a timed 5K race, a 2.5K fun run or walk, or a 200m Pup Run for kids and puppies. The main distances are open to solo runners and human-dog teams. The course uses Bechtel Park trails beside Waterloo's dog park. The loops are short enough for walkers, first-timers, and canicross teams, as well as people aiming for a faster run. The first edition raised $16,000 for the Humane Society and had over 200 dogs running with their humans. Entry includes snacks, a shirt, a finisher medal, and swag. Medals are awarded to runners and canine teams, ribbons to Pup Run kids, and extra fundraising options are available for individuals or teams.

The event begins in the morning and is designed for families and regular runners alike, featuring shorter distances alongside the longer road races. The 10k course consists of two loops on paved roads and bike paths, while the 5k is a single loop on similar surfaces. The 2.3k route utilizes the roadways in the west end of Springbank Park, and the Kiddy Trot covers the final 300 meters of the race path. All routes follow the park’s paved pathway system alongside the river, are traffic-free, and are clearly marked and marshalled. Costumes are a key element of the day: participants are encouraged to wear costumes while racing, with costume awards exclusively for those running in their outfits. Additionally, every child completing the Kiddy Trot receives a goodie bag at the finish line.
