BOISE -- Some call it the toughest half-marathon in the world, the Race to Robie Creek.
The race is always a great time, but the mood was a little different this year. Just five days ago, a bombing attack at the Boston Marathon killed three and injured dozens more.
Robie volunteers Lisa Harp and Barb Swanstrom met when they ran the Boston Marathon back in 2003, and have been friends ever since.
"Once you've done Boston, it never leaves you," said Swanstrom.
Which made the bombing at the marathon all the more heartbreaking for them, and another volunteer at the Robie starting line, Joe Zimmer, who ran Boston twice, said, "It was just terrible."
It was even more terrible for Ray Mullenax, who finished this year's Boston Marathon about an hour and a half before the bombs went off. But Saturday morning, something was different.
"It's wonderful. It's great," said Mullenax. "It's a great feeling right now."
Feeling great because while the attack is a tragedy, it's not nearly enough to shake the resolve of this country, or even keep these people off the road.
"What it shows is the spirit of the people, runners and non-runners alike, they just come to support, and it's really cool," said Zimmer.
The solidarity with the people of Boston was written on shirts and bibs, or shown with blue ribbons.
"It's very nice to see all the people wearing their Boston gear," said Mullenax.
Even people who have never run the Boston Marathon, like Richard King, were wearing ribbons. But they felt some sort of connection, even thousands of miles away.
"I think it's a tight-knit community here, "said King. "I see a lot of blue ribbons out here, and people are supportive."
Because for the people of Boston, Boise, and really everywhere, healing happens one step at a time, even if you're running.
"You just remember that for all of the bad, there's even more good," said Swanstrom.
