The inaugural Sturdy Dirty Enduro Series kicks off the second leg of this world's-first women's only enduro series in Oakridge Oregon. We are stoked to be shredding the iconic Alpine Trail in true Sturdy Dirty fashion. The challenge in racing Alpine Trail is not necessarily in it's technicality - but rather the sheer duration of this 15-mile journey through iconic PNW goodness.

There are six timed segments:

STAGE 1: Sourgrass Meadow to NF-1912 crossing (*** descending in ** miles)
Start your ride off in stunning fashion with a "is this real life?" blast through Sourgrass Meadow on fast rocky (and narrow!) singletrack before descending into iconic Alpine Trail flow with occasional roots, bumps, and several tight switchbacks. We could say this for all of our timed segments: you will get cookin', so be sure to look ahead and be ready for sudden and abrupt switchbacks.

STAGE 2: Jedi to NF-1912/Windy Pass crossing (*** descending in ** miles)
Ever wanted to ride like Leia? Pump and bump your way through a section of Alpine locals refer to simply as "Jedi" - a nod to the old-growth trees that the trail twists and berms its way around. Smile and shout-inducing berms and quick techy changes in direction are key features on this segment.

STAGE 3: Vista Meadow to NF-683 crossing (*** descending in ** miles)
After you stop for a couple of selfies with your friends and drink in the absolutely ridiculous views of Transition 3, get ready to start your engines again (after catching your breath). There are several tight switchbacks along this section, so check yo'self before you reck yo'self!

STAGE 4: Buckhead Shelter to NF-5828 crossing (*** descending in ** miles)
One word describes this segement: FAST AS HELL! Okay, that was three words...but you get the point. Long corridors of straight-ish trail allow you to pickup crazy amounts of speed. The exposure may give you pause to take it down a notch, and there are several sections of loose shale to test your handling skills.

STAGE 5: Rowdy techy downhill to NF-5828 crossing (*** descending in ** miles)
Stage 5 is short and sweet! This trail is steep and technical with rock-filled slalom turns which favor riders who don't mind getting a little rowdy.

STAGE 6: Jurassic Park to Westfir Portal (*** descending in ** miles)
No, a T-Rex may not be chasing you...but if one was....you could probably pick up enough speed in this section for that tiny-armed fella to eat your dust. This segment basically follows the mountainside one direction before a sharp left brings you back down the other way. Short punchy ups keep you on your toes until you get the once-in-a-lifetime experience of throwing down the hammer as you finish course in an all-out-sprint along the fire road which brings you right on back where it all started with a screaming crowd of your #1 fans and of course, cold beer!

Join us for a Sturdy Dirty pre-ride day of lady shred Sunday, July 23rd to check out the entire course (see website for details). We will also be holding practice shuttles $10 a person on Friday before the race.
