Do you have what it takes to race around the world? Yes. Yes, you do.
Runners are always looking for their next big challenge.
This month, 1,500 runners took off on the ultimate challenge: a 25,000-mile race.
This is not your average run. No race bibs. No timing chips. No bananas at the finish. In fact, there's not even a starting line. Say what?!
It's called Earthathon, and it's a worldwide digital relay race.
Runners from all over the world register for free, join one of 10 teams, and run wherever and whenever they please. Each participant logs their miles on Twitter using their team name and the hashtag #earthathon. Then the teams, each around 150 runners strong, can see their rankings and duke it out on the Earthathon website.
More than a race, Earthathon is basically a sweaty support group for life.
As runners tweet their mileage, their international teammates offer plenty of virtual support and motivation.
Since running is so often a solitary sport, Earthathon provides the chance for athletes of all abilities to come together and work toward an ambitious goal.
Dave Spencer, Earthathon founder, told Runner's World Newswire, "It goes way beyond running. The people doing it have created a group of friends from around the world."
And some of the runners are putting in miles to bring extra attention to important issues, too.
To them, the race is much bigger than a simple workout. One team, known as #HeForSheRunners, is "a derivative of the #HeForShe solidarity movement for #GenderEquality."
Others run for loved ones or combine the program with existing fundraisers for medical research or charities.
The race is long, and getting to the finish is all about teamwork.
The 25,000-mile journey usually takes teams five to six months to complete, and when one team finishes, its members join other groups to help them across the finish line, too. It's basically a 21st-century version of this:
The third Earthathon is going on now, and you can still sign up.
This is a unique opportunity to join a community of fellow athletes, runners, joggers, and walkers from around the world ... and to raise awareness for causes that matter to you! If you're ready for the race of a lifetime, register online, lace up your shoes, and hit the road.
