It's hard to run a marathon. We need to train for months to run 42 km. However, marathons seem easy for the 32-year-old Australian runner Erchana Murray-Bartlett. She just ran one every day for 150 days. She ran 6,300 km over five months from the top of Australia to the bottom. She beat the previous world record of 106 marathons. Ms Murray-Bartlett is a professional runner. She did not qualify for the Tokyo Olympics, so she did the marathons instead.

Murray-Bartlett broke the world record to raise awareness of species extinction. Australia is rich in biodiversity, but many animals are dying out. She raised $70,000 for a wildlife charity. She said the marathons were very hard, but she knew she could do them. She said she was "covered in sweat and flies, and everything ached". She kept telling herself to, "go 500 more metres". She said lots of tiny goals means you can do it. This is a lesson for all of us.
