tickets are now live for bigmoose ultra fun run 2026.

after an unforgettable 2025 ultra fun run – where thousands of you came together to run, walk, and fundraise – we’re back for 2026, and it’s set to be our biggest and most impactful year yet.

at bigmoose, and with your help, we’re creating a future where everyone can access the mental health support they need, when they need it.

whether you run, walk or jog, you will save lives. simply choose a distance which works for you – 5k, 10k, half marathon, marathon, or a 50km ultra marathon.
