Walla Walla GRIT 45

Development Route

“Walla Walla is famous for its renowned road riding, but the locals have been venturing into the Blue Mountains for years to get their fix of first class gravel roads. This course (the 45) and its partner courses (the 65 and 95) stay together for the first 24 miles, which includes the iconic,and challenging, Cottonwood Creek climb.”

“All three courses have steep sections some might walk up without proper gearing. Courses are designed for experienced cyclists and are not for the faint of heart! Both the 45 and 65 courses are the roughest on the climbs and have relatively smooth gravel on the descents. 700×32 is the narrowest we would go, but a 40mm tire might just be perfect.” By Alegro Cyclery.

The Dirty Freehub Team has not ridden this course, thus, the designation as Training Route. If you give it a go, leave us a comment below.

    Thanks for the feedback, it really helps make the site better!

    I have updated the map and cue sheet to correct for the bridge.

    … just looked at that climb that begins at ~ mile 13. Yes, that is a “bugger”. About 5 miles in length, with 1600+ feet of climbing, with an average grade well over 6%. And yes, there are some really sustained up sections like you mention. We found out about gearing the hard way in Tasmania. A lot of steep climbs. I now ride at 32 X 34 for my smallest gear. 36 X 30 is strong!!! Wow!!!!

    Did this ride today, 6/29/20 and it is epic. A correction to the RWGPS route; there is NO bridge crossing from the bike path within the first 1K; this is just a water weir “bridge”. The actual bridge across Mill Creek is approximately 1.5 K from this point – it’s pretty obvious. I actually parked the baseball park on the N side of Mill Creek, right off Tausick Way, so eliminated this ghost bridge crossing!

    The 3rd gravel climb is brutal, so far the most difficult (grade and surface) of all the DFH routes I have done. The 3rd gravel climb is nearly 9K and has sustained segments between 15 and 20%. It is rideable , but perhaps with more than a 36X30! But!, the descent is amazing!!! Gravel is perfect, descent is steep and extremely fast, as fast as you want! Wash board today was minimal, so no issue there!

    The terrain and views were absolutely amazing! Wheat and bean fields were in full bloom, temp was perfect – not sure I’d what to venture out in mid July or later as there is little shade to be found!
