Susan Marshall is back home and earning a well-deserved break after running from 6am to 11pm.... for 50 days.
She was the first woman - and fifth overall - across the line in the Sri Chinmoy Self-Transcendence race in New York.
The race is 3100 miles long - 4988 kilometres - and participants have 52 days to finish - which is basically the equivalent of running two marathons each day.
Susan is just the ninth woman to complete the race in 26 years. So would she do it again?
