All 2025 GLER Races and Course Loops will begin and end at our GLER Race HQ's Start/ Finish lines located at Tulip Hill Picnic Area on the northeast corner above Green Lake.
The course has a widely varied trail surface that includes well maintained single and double track trail, grassy single track, dirt roads and a bit of asphalt too, on a course that is extremely "runnable" as trail courses go.
- Each fixed distance (100K/50K/25K) race lap or loop is almost exactly 8 miles long.
Two ascents and one long descent traverse the upland forest. These steep shaded trails have some roots, ruts, and stones. The trails in the upper meadows are mostly dirt, grass, rolling, and unshaded.
- The uppers meadows are referred to as the Serengeti. The 3+ miles of running around the Serengeti per each course loop can make for a challenging summer ultra if Mother Nature offers a warm sunny day.
- The lower lake section of trails are shaded, have a few roots and are generally flat.
- Overall, the course lends itself to quick running without technical hikes.
- The 100K race is 8 total course laps and the 50K race is 4 course loops. The 25K race is 2 course loops. - The 12 Hour timed race course is different than the 100K/50K/25K loop. The 12 Hour timed loop will be run in a clockwise 3 mile loop around the Green and Round Lakes only. All timed racers will continually circle only the lower, lakes portion of the course as many times as they can.
Course Time Limit
The Race clock will be a full 15 hours with the 100K starting at 0600AM. The 50K race starts at 0700AM. The GLER 12 Hour Race starts at 7AM and finishes at 7PM. The 25K race starts at 0800AM. All fixed distance racers (100K, 50K and 25K) will have until 9:00PM to complete their race. All fixed distance racers must start their final course loop by 6:45PM. Any racer starting their final course loop after 6:30PM must have their own light before they start their final loop. A racer may have a "running buddy" for their final loop when starting at 6:45PM or later. Running buddies may not "mule" food nor beverages for the racer they are running with.
The 12 Hour race clock will start at 7AM and finish at 7PM. All 12 hour racers have the full 12 hours to complete as many loops in that 12 hour period as possible. Any Final loop completed after 7PM WILL NOT COUNT.
