My Story

1 Sep 2025

I take pride every year to participate in this challenge. Last December I was struck by a DUI driver that caused me injuries. I thought I wouldn’t be able to participate this year, but here I am, less of a riding goal this year, but I’m here.

My Legacy

Here's my personal impact over 6 years to fight kids' cancer and save little lives.
