"I have already reached my 100 per cent for the challenge in community service but I wanted to add this on anyway as it is something I want to do."
She has always had a passion for cycling and ever since she was in year four she would ride a bike around the home until her father David brought her a road bike a few years later.
"I have always loved riding, I ride to school most mornings along the limestone from Haumoana and me and Dad do lots of rides together."
Lily said she was really excited about the ride on Saturday and would be wearing a Cranford Hospice shirt during the race.
"They have given me a shirt and donation boxes and are also looking for sponsorship from other places."
She has never done a ride like this before and was looking forward to achieving her challenge.
It would take her six hours to complete and she would ride around 150km.
Her mother, Erica Stephens, said usually you had to be 16 and over to enter the individual part of the USO ride but they were allowing Lily to do it at just 12, "which was great".
She has travelled the country already this year entering in a variety of competitions from the North Island Champs in Taupo where she got second to the New Zealand champs in Palmerston North.
"I just want to keep cycling and I create my goals as they come. I don't want to make it too competitive as I want to keep enjoying it," Lily said.
The ride on Saturday is extremely special to Lily and she hoped to raise $500 by the end of the race, which she could then present to the Cranford Hospice.
Cranford Hospice marketing fundraising manager Nathalie van Dort said they were very excited about having such a young person support Cranford in this way.
