My Story

7 Jan 2026

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.

    A huge thank you to everyone who has supported my quest. Together we have raised over $7,500 and with your support I rode 574km’s this August. I was delighted to ride with my 8 year old great nephew Fionn who also joined the challenge. Thank you all for helping to beat kids cancers and supporting Sick Kids Hospital. Let’s keep up the fight. 💪🏻👊🏻🚴🏻‍♀️
