OWASSO, OKLAHOMA -- Distance and perspective are two things runners have to figure out.
How far can you run and where are you going?
The Henrie family of Owasso always had the distance part figured out.
Father Danny, Mother Jill, and their three children including Danielle, they could run.
Even Danny trained himself to run for distance.
"I played baseball and football," he says. "So we didn't run unless we lost."
Their son Hunter and his little brother Hance were the fastest.
They all started running the Family Relay of the Memorial marathon as soon as the class came open.
For five years running the Henries didn't finish out of 3rd place.
They won the five person relay in 2008.
They were best when Hance ran the anchor leg.
"Hance was full of spirit," says Jill Henrie. "It always made sense for him to run the anchor leg."
The perspective part of running is what changed for their family.
In previous years running to remember always meant remembering the bombing victims.
But in 2011 the lost their anchor leg.
Hance was a passenger in a car hit by a drunk driver.
He died a short time later.
The Henries thought they'd run their last race.
"When we lost him we really thought we were finished," says Danny.
Race morning of 2016 and thousands of runners and families gathered in downtown Oklahoma City.
The Henrie family arrived ready to run another relay.
Jill says, "Those seconds of silence in the beginning, those really tug at your heart strings."
In fact, there were three different relay teams also running under the Team Hance banner.
Many of them were co-workers and friends who convinced Jill and Danny to change their perspective, to run because that's what Hance would have wanted.
"He wouldn't like us to just throw our hands up and do nothing," says Jill.
26 miles is a long way to run.
Most people can't do it alone.
They need support.
They need help.
That anchor leg seems a long way off.
But the finishers here know that perspective is important.
"We run to remember," says Danielle, "And we run because we remember."
Having a reason to run keeps the feet moving.
