Estes Park's Annual Frost Giant 5K and 10K races mark their 33rd anniversary during the winter season in this mountain community on January 29.

About 350 participants are expected to take off from the Estes Park Town Hall, 170 MacGregor Ave., before running the course that travels through MacGregor Ranch pastures before returning to the starting point. Ten age groups will participate, beginning with children up to eight years old. Seniors over 70 also have their own competition.

The 5K race gun goes off at 11 a.m.; the 10K race starts at noon. The Frost Giant is held regardless of weather conditions. In the event of truly vicious winter conditions, only the 5K may be run. Professional medical staff will be on site.

Trophies will be presented to overall male and female first and second place winners with a medal being presented to the overall third place runner. First and second place runners in age divisions receive medals while third to fifth place runners will be awarded ribbons for their efforts. Additionally, there are drawings for gift certificates and prizes.

Chip Salaun, world class triathlete, mountaineer, author and environmentalist, was co-founder of the Frost Giant. He created the name, drew the original logo, laid out the course, pulled the first start trigger and was the catalyst behind the success of the winter mountain run. In late April 1985, Salaun vanished on New Zealand's Mount Cook.

Registrations received by 5 p.m. Jan. 27 range from $25 for one race only to $33 for both races. Registrations on race day range from $30 to $38.
