My Story
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.

Riding in the rain 🌬️🚴🏻♀️🚴🏻♂️💦
20 Aug 2025Families 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 💪🏻🚴🏻♀️🤞🏻

Michael Garron - an inspiration
13 Aug 2025Today is Kick Cancer’s Butt day for the Great Cycle Challenge. Each donation today will be matched up to $1,300,000 by the very generous Garron Family. Sick Kids and their fight against childhood cancers is very near and dear to the Garron family.
Michael Garron died at the age of 13 in 1975 of a rare form of cancer. Before he died, he told his mother that he was afraid he would be forgotten. “As long as I'm alive, no way will you ever be forgotten,” she replied. So on August 13th let’s all remember a remarkable little warrior. Thank you Garron family for everything you do to help healthcare 🙏🏻🙏🏻

Riding with Mika 🚴🏻♀️🚴🏻
5 Aug 2025Mika is my 11 year old neighbour who, when he heard about the GCC to help Sick Kids Hospital beat children's cancers, jumped in with both feet! "There are many people in my life that have had cancer, such as my mom, my grandma, and some of my friends. One of my best friends uncle just passed from cancer, and I want to raise money to find a cure." Wow, what a profound and powerful statement of commitment from a young man. I am honoured that the GCC has given me the opportunity to ride with my new young friend Mika. He is outstanding. I look forward to more rides with Mika.
Here is Mika's link if you would like to support his wonderful quest:

DAY 1 LET’S GO! Time to fight kids cancers. 👊🏻
1 Aug 2025On one hand today is day 1 of the Great Cycle Challenge but it is another tough day for the families with a loved one fighting cancer. Today, during my first ride, I thought about how very important it is for so many that together we help fund Sick Kids fight against cancer. I’m riding for my niece wee baby Julia, I’m riding for my Dad, I’m riding for friends. THANK YOU for helping me and Sick Kids kick cancers butt. LET’S GO!

New year, same challenge. Let’s fight kids cancers!
23 Mar 2025Although there is still snow on the ground, it’s time to start thinking about the Great Cycle Challenge and riding for Sick Kids! This year I have a secret goal to surpass 500kms … if the weather cooperates I’d like to pedal 10 kms for each year I’ve been blessed to celebrate on this beautiful planet. Time to start training!
