2023 Brisbane 7 Day Challenge

Help me support kids in need

We all should give back to the society. Riding bikes for a cause and creating awareness about a disease or issues is giving back to the society which we live. 

My Updates

My personal fundraising goal is $6000

Hello! I need your help please! 


I have challenged myself to cycle over 1000 kilometres in 7 days on a tour of South Island New Zealand in March as part of the 2023 Chain Reaction Challenge. This event raises much needed funds for kids in need. The children's charity targeted for the event is AEIOU. My efforts are to support children on the Autism Spectrum Disorder.


This is a personal effort for me as I have a daughter with Autism living her best life. This Chain Reaction Fundraising event can help me respectfully give back to the charity and creating awareness about Autism (ASD). My personal fundraising goal is $6000. I would be grateful if you could help me make a difference and donate to my fundraising page
