Update Monday afternoon
The first 2,100 bib numbers for the annual half marathon went on sale at noon, and sold out in 10 minutes, according to race officials. To enter a second-chance drawing, see details below.
The Race to Robie Creek half marathon is brutal, with an uphill climb and a downhill finish.
The rush to register for the 13.1-mile race is just as tricky.
The registration process for the 39th annual Race to Robie Creek — the unofficial kickoff event for the Boise area running season — starts at noon Monday. The first 2,100 runners and walkers can register at robiecreek.com for $50 (plus $3 in fees).
Those bib numbers are expected to sell out in less than an hour, according to race officials.
A second-chance drawing, for at least 200 more spots, starts Monday afternoon and continues through 5 p.m. Sunday. Cost is $7; more detailed information is available at the race website.
The Race to Robie Creek starts at noon on Saturday, April 16. The course starts at Fort Boise (elevation 2,725 feet), climbs over Aldape Summit (elevation 4,797) and finishes at Robie Creek campground (elevation 3,065).
