Mrazek Tr32 is one of the best trails in the Bend area, offering fast terrain over a long riding season.
Mrazek Tr32 wanders 15mi to Metolius-Windigo Tr99, so is long enough for a destination OAB ride, and is one of the best downhill segments in the Cascade Range.
As with other Bend area trails, the terrain is moderate, enabling long distance rides.
With a judicious amount of fireroad use, Mrazek Tr32 can be combined with the Phils Tr42 trail system, however there is enough terrain in each trail system to fill a day.
A 24mi (2150' ascent, 4500' descent) Bachelor to 'Bend' option is to combine Flagline Tie Tr40.1, Flagline Tr40, Metolius-Windigo Tr99 and Mrazek Tr32, with the moderate ascent and great views of Broken Top leading to the long Mrazek downhill, covering terrain which holds up well over the season.
Aside from the usual OAB ride, there are two lollipop loop options which cover terrain unique to Mrazek Tr32, and so are not just a redo of some other ride.
Both of these loops rely on Metolius-Windigo Tr99 as a connector.
The first is a 38.5mi (5300' ascent) CW lollipop, with Mrazek Tr32, Farewell Tr26 and North Fork Tr24.2.
To minimize user conflict (i.e. bikers running down hikers), North Fork Tr24.2 is only open to bikers as an uphill trail.
Just as well, since the 1300' Farewell Tr26 is easier to handle as a downhill trail.
The lower half of Farewell Tr26 has a loose, rocky trail surface, so is technical in either direction.
The second loop option is a 40mi (5600' ascent) CCW lollipop, with Mrazek Tr32, Swampy Lake Tr23, South Fork Tr25 and Farewell Tr26.
The Swampy Lake Tr23 descent is rugged enough to justify the 1300' mid-ride Farewell Tr26 ascent.
This may be the best way to ride the upper section of Swampy Lake Tr23.
