BOISE -- If you want to run the toughest half-marathon in the Northwest, you first have to get through a very competitive registration process.
Registration for the 36th annual Race to Robie Creek started Monday at noon, and was over in just 13-and-a-half minutes, according to race organizers.
Only 2,436 racers are allowed and there are always a lot of people hoping for a chance to test their mettle in the grueling 13.1 mile half-marathon that features a lot of ups and downs (mostly ups).
The race begins at Fort Boise, where the elevation is 2,275 feet and ends at Robie Creek Campground at elevation 3,065 feet.
The theme for this year's race is Robie, or Not to Robie -- a nod to Shakespeare's Hamlet.
There will be a second chance to register on beginning at 8 a.m. Tuesday when an additional 200 spots will be available for the race. The winners will be selected during two drawings next week.
