Featured Fighters
Some people choose to give 100%,
for others it’s their only choice.
Meet our 2026 Pedal the Cause Featured Fighters. They are members of the Pedal family – survivors, fighters, doctors, researchers and caregivers – for whom the fight with cancer is personal. Together, we can create a world without cancer – all cancers, for everyone.
2026 Featured Fighters
Dr. Sheila Stewart
Meet Dr. Sheila Stewart, a pioneering researcher at Siteman Cancer Center whose groundbreaking work is uncovering how aging influences cancer development, progression, and response to treatment. Dr. Stewart received one of the very first Pedal the Cause research grants in 2010, the inaugural year Pedal began funding cancer research. Since then, Pedal’s investment has helped fuel innovative ideas that might not have been possible through traditional funding sources, enabling her research to progress from foundational discoveries to promising clinical trials that are bringing new hope to patients.
Christine and Kim Marx
Meet 2026 Pedal the Cause Featured Fighters Christine and Kim Marx. As a married couple, they know firsthand how cancer changes lives—from surviving it to helping a loved one through it. Today, they're both two-time survivors, proud members of our Living Proof community, and ride together at Pedal the Cause to help ensure more patients have the chance to hear the words, "no evidence of disease." Their story is a powerful reminder that every breakthrough starts with research, every mile fuels hope, and every rider has the power to change the future of cancer.
