GLER 2025 Race Notes

Team GLER is looking forward to executing our best race ever this coming August.
We are happily, excitedly, and proudly announce the addition of our newest race, the GLER 12 Hour Race.

We are maintaining our four age groups for all four races; Open (39 and Under), Masters (40-59), Senior Masters (60-69) and Ambassadors- 70 and older.

ANNOUNCING OUR NEW GLER 12 Hour Race

The GLER Team is pleased to announce that we have add a 12 Hour Timed race- our own GLER GALEFORCE 12 hour timed event to our roster of races. We’re calling it GLER GALEFORCE (right now…) because we fully expect people to be running like the wind on this course.
– The GLER 12 Hour course sticks to GLSP’s lake level; racers and runners have 12 hours to complete as many 3 mile clockwise loops as they can around the Green Lake/ Round Lake Loop.
– We are very exited to offer and present this new this 12 hour timed race to the ultrarunning community.

Description

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.
