Alan Nawoj (San Diego, California) is excited to represent the USA in the 2025 World Marathon Challenge (WMC) aka "777", an extraordinary endurance competition that takes runners around the globe to each of the 7 continents in 7 consecutive days to run a full (26.2 mile) marathon on each continent.

Considered one of most difficult endurance races on the planet, runners must complete 183.4 miles of running while traveling over 40,000 kilometers across numerous time zones in weather conditions ranging from extremely cold and windy to very hot and humid over the course of the week. Most of the recovery time from each marathon will take place on the plane while traveling from one continent to the next.

This will be the 10th anniversary year of the WMC and will feature a full-field of 62 runners from 20 different countries. Click here to view a complete list of the 2025 competitors. To date, less than 200 runners have successfully completed the 777 challenge.
