Kelsey Pfendler is almost there.
After weeks alone on the Pacific, she's closing in on Hawaii — and we've been cheering her
on every mile of the way.
Before she began, she stopped at Denny's for one last meal on land. Now our team wanted
to send some encouragement for the final push.
Watch the video and help us cheer You Row Kelsey across the finish line.
