Steamboat Springs If you're still considering registering for the 20th Annual Steamboat Marathon, you'll have to do the first 20 miles on your own.
While the 26-mile race has already been booked full, there is unlimited space for those still wishing to compete in the 6.2 mile race.
The half-marathon, or 13-mile race, also is sold out, said Judy Wiesner, marketing director at the Steamboat Springs Chamber Resort Association.
About 1,400 individuals are scheduled to compete in the marathon and half-marathon, including 900 people in the half marathon.
The 6.2 mile race, or 10K race, can be signed up for until June 2, Wiesner said.
The events take place June 3.
The 6.2 mile race, which also is called the 10K Run and Fitness Walk, begins and ends in front of the courthouse downtown and costs $20 to enter.
The 10K course goes through Strawberry Park and Old Town Steamboat Springs.
The marathon begins at Hahn's Peak Village and finishes at the courthouse.
The half marathon starts at the mid-point of the marathon course, known as Moonhill, and ends at the courthouse.
With the addition of online registration for the competitions, Wiesner said the 2001 marathon and half marathon sold out faster than ever before.
The marathon was sold out March 1 and the half marathon was booked full as of March 13.
About 60 percent of the participants registered online, Wiesner said.
There also will be a half-mile "fun run" for children, which will be held downtown during the June 3 events.
Entry deadline is June 3 at 11 a.m.
