My Story

10 Jun 2025

This August, I am again taking part in the Great Cycle Challenge to fight kids' cancer!

Why? Because right now, over 1,700 children are diagnosed with cancer every year, and it's the biggest killer of children from disease in Canada.

Kids should be living life, not fighting for it.

So I am raising funds through my challenge to help these kids and support SickKids Foundation to allow them to continue their work in developing treatments and finding a cure for childhood cancer.

Please support me by making a donation to give these kids the brighter futures they deserve.

Your support will change little lives.

Thank you.

    Families with kids fighting cancer don’t get to “choose” good, sunny weather days … so Mika and I rode today despite Mother Nature insisting on keeping us wet & cold. Had we just waited 24 hours … ⛅️🙃🤷🏼‍♀️🤦🏼‍♀️ Glad we showed our true grit and determination. Thank you all for your help and support! I’m almost at 400kms … tomorrow 💪🏻🚴🏻‍♀️🤞🏻
