Joseph Tebutt and Miya Pirini have battled their own health issues and are now spearheading a fundraiser to help others facing medical emergencies.
The two Dargaville friends, 9 and 10, plan to participate in the Selwyn School cross-country run to raise funds for the Northland Emergency Services Trust.
What is remarkable about their sporting pledge is Joseph uses a wheelchair permanently, due to a multitude of congenital issues, and Miya is only able to do minimal physical activity as she builds her strength and recovers from a life-threatening bout of rheumatic fever.
But both will finish the 2.5km course at the annual cross-country day next Friday atop a stretcher carried by six teams of volunteers. The two battlers are looking forward to the challenge.
Joseph was sure he would be encouraging his carriers around the course. "I want them to go fast but not too fast," he said.
