What's the furthest distance you've run?

I’m 23 years old and have always been an incredible endurance runner. When I was 8 my mom and I did a mock half marathon and did a 13 mile run. By the time I was 12 I could finish a marathon at 26.2 miles. Now my furthest distance is 54 miles as of Jun 2019. I do running during the Summer and Christmas Break mostly when I have time off University.

This is a question for everyone though I would like to hear from some people with experience in long distance running.
