Led by a teenage cancer survivor, nearly 5,000 people cycled their way to charity on Sunday, participating in the annual CN Cycle for CHEO and garnering a collective $570,000 to help support kids with cancer.

The start line move to the National War Museum excited organizers with the large turnout.

"Registration is up," said Kevin Keohane. "The move downtown seems to be extremely well-received; people seem to love that."

But for the people straddling bicycles, it came down to helping out rather than looking for recognition.

Fourteen and cancer-free

"It makes you feel good because it's helping a lot of kids," said Lauren MacLeod, the cancer survivor.

"It's scary and horrible to go through it, so as much as they can help to make it better, it's awesome."

Just a day shy of 14 years old, MacLeod is part of the McDonald's Dream Team this year. After two and a half years of treatment for leukemia, she's now cancer free.

It was a birthday present for her to remember as she led the way for the 35-kilometre trek.

"It's been fun to be a part of this. CHEO was always great through my treatment, so it's a good experience. I want to help and give back."

Ronald McDonald House and Candlelighters will also benefit from the event.
