I've never done a Backyard Ultra before and this was the perfect start! A simple format. Nothing too fancy, but well organised. Very friendly and enthusiastic organisers. Fun atmosphere. The 12-hour format worked really well as a first-time backyard race. Really enjoyed it!

I had an incredible experience at this event. The support staff were outstanding from start to finish, and the atmosphere throughout the day was electric. A special shout‑out to the massage therapist who worked her magic on me after four laps — she genuinely saved my race and made it possible for me to complete a fifth. The food was excellent, the fellow runners and crews were unbelievably supportive, and the venue itself was fantastic. The course was challenging but fun, and the whole event had a brilliant community feel. I’ll definitely be back next year.
