Most of the United States’ eastern seaboard is preparing for the impact of Hurricane Florence, a Category 4 storm. And one group of athletes prepares to race in front of it.

Participants in the Shenandoah Tough, a part of the Adventure Racing World Series, are preparing today to compete on a 250-mile wilderness course that traverses Virginia.

More than 1 million residents along the coasts of the Carolinas and Virginia have been ordered to evacuate inland. Hurricane Florence is packing winds over 130 miles per hour. Forecasters expect it to strengthen before making landfall sometimes Thursday.

It’s a scary storm. But for a group of adventure racers, it’s another element to outrun.

The Shenandoah Tough race, which was scheduled to start on Thursday at 8 a.m., has now been moved 12 hours ahead. It will kick off at 8 p.m. today. Organizers hope the earlier start and expected track of the storm will allow racers time to complete the course before heavy rains inundate the region.
