You may think you're a runner, but you probably don't run 15 or 20 miles every day!
One group has been running that much or more for the past week or so.
One step at a time, these runners are making their trek from Boston to West Palm Beach.
Their goal? To help kids realize the importance of exercise and eating right.
Billy Sheenhan is a runner, but he helped to organize the trip.
"Our goal is to bring attention to raise money and bring awareness to the issue of child obesity and youth fitness," said Sheenhan.
Trek USA Team is a non-profit organization who's mission is to inspire the next generation of children to set goals, fulfill their dreams, and to lead a healthy lifestyle.
"We are trying to send a message out there that this is equally important to prepare younger generations to be physically fit," said Sheenhan.
Each runner averages 15 to 20 miles a day and when it's all said and done they'll have gone through nine different states in just 11 days, and the most amazing thing is they did it all on foot.
David Salem and Amory Rowe ran the Boston marathon last week. Now they're part of the Trek Team making their way through Savannah.
" We do this to inspire children in a particular under the age of 18 to start small whether it's five steps or fifteen steps at a time. Whatever just get going cause it will make feel great," said Salem.
With two days left in the Trek relay, the 20 runners are just taking it one mile at a time.
The group has already raised over 100 thousand dollars. If you would like to donate or learn more about the organization you can visit their website at www.trekrelay.org
