THE DREAM

About Waldo 100K — what makes it special

ABOUT THE RACE

A day you'll remember,
long past the finish line.

This is a 100K loop course starting at Willamette Pass Ski Area (elevation 5,120 feet), 70 miles east of Eugene, Oregon.

It crosses several peaks, including Fuji Mountain, The Twins, and Maiden Peak, before returning to the ski area.

Most of it is singletrack, with some remote stretches, and views of Waldo Lake open up repeatedly along the way.

Amy ChamberlainRan in 2023
“This year I wanted to leave it all on the trail. Waldo was both my first 100k and a notoriously challenging course.”

After withdrawing the previous year with an Achilles injury, the runner took on Waldo 100K. Solid training, cooler weather and efficient crew support helped them run their first 100K.

“This was the fourth time I’ve run and finished this race. It never gets any easier either.”

Heat and long climbs challenged the runner even on their fourth Waldo 100K finish. They kept moving late in the race to place 6th overall in 10 hours 36 minutes.

Where's Waldo 100K, which passes by Waldo Lake, began in 2002 when Bend-area ultrarunner Curt Ringstad stitched together several trails to create the course.

Legend has it that 37 runners took on the first race that September, and 4 of them left course on the first aid station and failed to finish.

It has since become one of Oregon's signature ultramarathons, serving as one of the few Oregon qualifiers for the Western States 100 Mile,

and as its popularity grew, entrants have been selected by lottery since 2015.

Course is a 62.5-mile (about 100km) loop course starting at Willamette Pass Ski Area (elevation 5,120 feet), about 70 miles east of Eugene,

climbing and descending several peaks including Fuji Mountain, The Twins, and Maiden Peak before returning to the ski area.

Most of it is singletrack trail, including fairly remote stretches, with a series of points offering views of pristine Waldo Lake from different angles.

With over 11,000 feet of total elevation change, it takes a heavy physical toll,

but is regarded as a course that rewards runners with the overwhelming scenery deep in the Cascade Range in return.

Typical race-season temperature: around 18°C (65°F)

Stations & transport near the venue

Getting to the start

No public transit; start/finish is the Willamette Pass Ski Area day lodge right on Hwy 58

Stations & transport near the venue

This is a remote mountain-pass venue with no bus, rail, or transit card of any kind.

Fly into Eugene, OR and rent a car for the roughly 1.5-hour drive up Highway 58;

there is no rideshare coverage this far out, so self-driving is effectively mandatory.

READY TO RUN

From race morning to after the finish.

Your start time, fuel and bag drop.
Know them ahead and the run feels easier.

The start is at 4:00 a.m. on Saturday, while it's still dark.

Time limit is broken down by segment — Charlton Lake at 2:00 p.m., Road 4290 at 3:15 p.m., and The Twins at 5:30 p.m. —

and each aid station must be passed before that time.

Aid station intervals are relatively tight, at 4.9 to 7.5 miles, and drop bags can be left at four locations —

Fuji Mountain, Mount Ray, Charlton, and Road 4290 — which must be submitted by 9:00 p.m. Friday.

The finish cutoff is 10:00 p.m. (18 hours total), and runners who come in within that time receive a commemorative finisher's hat.

Entry requires having completed a trail race of 50K or longer within the past two years, so newer trail runners will need to qualify through another race first.

Check-in is available from 4:30 to 9:00 p.m. the day before, and again from 2:30 a.m. on race day,

and a pacer is allowed to join starting from the Charlton Lake point.

Times are local to Oakridge. Check the latest official information before the race.
