The 13.1-mile Race To Robie Creek is billed as "the toughest race in the Northwest." In September, hardy souls like Matt Green will get the chance to cover 26.2 miles on that course.
Sept. 28 will mark the inaugural Double Robie, which will consist of running the Race To Robie course, then turning around and returning to the start. The 16.6-mile Aldape Challenge, a run from Fort Boise to Aldape Summit and back, will be the same day.
"Robie is a rite of passage in Boise, and the Double Robie sounds a little more nuts, so I had to do it," said Green, 42, who has already entered.
Green has not run the Race To Robie Creek since 2008. A battle with a foot injury kept him from running seriously until nearly two years ago - Green said he hasn't run in a marathon since. But the Double Robie was just what he needed.
"I really hadn't found anything to motivate me, but now I have the perfect excuse," Green said. "I've kind of always wanted to do it. I know people who will start at the finish early, run to the start, then do the regular Robie, so it will be cool to have a full marathon on that course."
Race director Bart Davis, a Boise native, moved back into the City of Trees earlier this year after nearly 20 years away. He recently served as the director of the Long Beach Marathon in Southern California, which had more than 20,000 entrants.
"Everyone loves Robie, so it's kind of something where you want to take it to the next level," Davis said. "It's kind of something I've always had in mind."
Green said he's sought out races that were "above his head" when he signed up, but pushed himself to train to complete them - he couldn't swim the length of a pool when he signed up for his first triathlon.
"When you think of it, it sounds really tough, but there's time to train, and if people put in the time, they can do finish it - and that will be a pretty good accomplishment," Green said.
There is another perk to the two new races - most of the last half for both will be downhill.
"That will be nice," Green said. "And you'll finish right in town. Won't need to take a bus back."
