Frosty Bottom Marathon & Half Marathon

The Frosty Bottom running race returned in 2018 after a one-year hiatus and for the first time was extended to the marathon distance!
Held simultaneously with the Frosty Bottom bike race, but with some separate elements of organization, the Frosty Bottom MARATHON travels point-to-point from Kincaid Park to the Hillside Trailhead (adjacent Abbott Road) and is capped at 100 entrants.
In 2020, The Frosty Bottom HALF MARATHON is being added. It travels point-to-point from Kincaid Park to the Northern Lights Bridge (near Goose Lake Park) and is capped at 100 entrants.


The MARATHON course will be simplified in 2020 by eliminating the two add-on loops of the previous two years in Bicentennial Park.
It starts 1/4-mile down the hill from the Kincaid Chalet (same as the bike race) and then follows the Raspberry Road multi-use path to Raspberry Trailhead. From there, runners take the Middle Earth singletrack trail to where it intersects the Coastal Trail a mile from Kincaid Chalet. Then it follows the bike course on the Coastal Trail, Chester Creek Trail, Tour of Anchorage trail and Hillside multi-use trail to the finish at Hillside Trailhead adjacent to Abbott Road (this is a NEW finish line; it ended in recent years at Hilltop Ski Area). The marathon course includes 1,371 feet of elevation gain and according to GPS measures 26.08 miles.
Here is a Garmin interactive map of the marathon course:.

The HALF MARATHON course starts 1/4-mile down the hill from Kincaid Chalet and takes the Coastal Trail about 9 miles. Then it turns right (east) on the Chester Creek Trail about 4 miles to the finish just across the Northern Lights Bridge. A short access trail then leads to the Goose Lake Park parking lot.
This distance according to GPS measures 13.12 miles and includes 281 feet of elevation gain. Here is a Garmin interactive map of the Half Marathon course:

Course Markings

For the MARATHON, the Raspberry Road multi-use and Middle Earth singletrack will have signs and pin flags as needed. Once the course joins the coastal trails, runners will follow bike race markings the rest of the way.
The HALF MARATHON runners will follow bike race markings the entire distance.

Aid Stations

The MARATHON will have aid stations at Airport Park off E. Northern Lights Blvd. at mile 10.7, at the Northern Lights Bridge (near Goose Lake Park) at mile 17.5 and at the Hillside Trailhead finish line.
The HALF MARATHON will have an aid station at Mile 6.5 at Airport Park off E. Northern Lights Blvd. and at the Northern Lights Bridge finish line. (near Goose Lake Park).
All aid stations will have water, sports drink and sustenance (sugary and salty snacks).
Water will be available at Kincaid Chalet before the start.


This is a winter race! Be prepared for inclement weather, sub-zero temperatures and wind (particularly on the Coastal Trail).
Dress in layers appropriate for the conditions. Recommended items include a windbreaker, neck gaiter (Buff), chemical hand and foot warmers, and a water bottle or Camelbak (test your hydration system in the cold to make sure it doesn't freeze up).
Runners in both races should give right-of-way to bikers who are traveling much faster than foot travelers, as well as recreational skijorers, skiers and other trail users.
Be alert for wildlife, particularly moose, and consider carrying bear spray. Buddy up and bushwhack around wildlife if necessary.
Headphones are allowed but not advisable (because they can impact your awareness of your surroundings).
We love dogs but they are not allowed for this race, sorry.
