Many people could not run a marathon. They would need to train for months to be in shape for the 42-km run. However, marathons are no problem for Australian runner Erchana Murray-Bartlett. She just ran one every day for 150 days. The 32-year-old ran 6,329 km from the top of Australia to the bottom. Her five-month coast-to-coast running is a world record. It's the most consecutive daily marathons ever run by a woman. She smashed the previous record of 106. Ms Murray-Bartlett is a professional runner. She could not qualify for the Tokyo Olympics, so she did the marathons challenge.

Murray-Bartlett ran her marathon number of marathons to raise awareness of species extinction in Australia. The country is rich in biodiversity, but many animals and plants are dying out. She raised $70,000 for a conservation charity. She said the record was an incredibly tough five months. She knew she could do it. She said: "Even though sometimes you are covered in sweat and flies, and everything ached, I thought: 'No, I can go one more kilometre' or: 'No, I can go 500 more metres'. If you keep stringing together little tiny goals, you can make it." This is a good lesson for all of us.
