Bend and Central Oregon is considered to be one of the capitals of mountain biking in the US and for good reason. To grasp the amount of trails available there are approximately 262 miles of continuously linked single track
trails that can be accessed from the west side of Bend. There is another 222 plus miles in less than an hour and a half drive from town. Most of these are smooth and fast on pumice soils. Lots
of towns claim extensive mountain bike trail mileage that in reality
contains a lot of dirt roads or atv trails. Some of
the trails elsewhere in Oregon like in Oakridge or on the North Umpqua
are on steep hillsides with blind corners where going off the trail at full
speed is going to involve some air time and big trees. For most of the
trails in Central Oregon, your speed is only limited by your cornering
ability. Although the majority of the trails are technically easy and
not too strenuous, they are far from boring if you ride them fast
enough. If it is any indication of the quality of cross country riding in Central Oregon, three of the four top pro men finishers in the 2008 USA Cycling Mountain Bike Nationals were from Bend.
The risk averse or those in the DWI (dads without insurance) category will be glad to know that the few rocky technical sections are generally short and easy to walk. For those who are looking for technical challenges, there are increasing numbers of optional man made features popping up. Extensive free ride parks are in the works like the Funner and Tiddly Winks trails. If you are planning a vacation and are really into man made features head to Post Canyon in Hood River. Although there are some technical rock features here and there with some trails having more than others, Central Oregon does not have anything like southwest "slick rock".
There are a couple of other things that make Central Oregon riding great compared to say, a lot of five star trails in the Rocky Mountains. The trails here are not part of any cattle range except for Gray Butte so you don't need fenders to keep the crap off your Italian shoes or ride trampled mud that has dried. There are horses on a small portion of the trails but except for some of the Sisters area rides the horse traffic is pretty light. Also, these trails are not shared with ATVs like so many in the Rockies are. ATVs have a separate trail system here.
Most of the trails are pumice soils. Except for the very early season, where the ground is thawing on top and frozen underneath, there is generally no mud and if it rains the trails become firmer. Later in the year, on heavily used trails, the pumice gets ground into a fine dust (moon dust) which on group rides can be an issue. For the most part, the trails are maintained and, in many cases built by the Central Oregon Trail Alliance (COTA). The Forest Service does clear some trees on some trails but thanks to legacy of our beloved ex "environmental president" and his appointed cronies, they have less and less funds every year, and rely heavily on COTA.
GEAR: Cross country full suspension mountain bikes are more than adequate. The trails are easily smooth enough for hard tails. Due to the nature of the trails, single speed and cyclo-cross bikes are becoming increasingly popular. Leave you downhill body armor in the car, you won't need it here and you will look very out of place. That said there is a about a hundred yard freeride park about a hundred yards from the Phil's trail head and the small new Lair freeride park where body armor might be appropriate.
CAMPING: Despite the amount of public land that surrounds Bend, there are pathetically few campgrounds close to town other than Tumalo State Park. (There must be some type of conspiracy with the abundant local hotels.) There are campgrounds near most of the high lakes west of Mount Bachelor but they are at least half an hour from most of the local trails, and town. There is some great riding up near the high lakes it just depends on what you want to do in the area when you are not riding. You can stay anywhere in the National Forest for two weeks, unless otherwise signed. The vast majority of trails are on Forest Service land and this land starts close to town. If you do camp outside of a campground, pack your garbage out and keep the area clean. Public showers can be had at the Juniper Fitness and Aquatic Center which also has a sauna, hot tub and steam room!
WEATHER and GEOGRAPHY: Central Oregon is frequently referred to as the high desert. Most of the Bend area is in a rain shadow of the Cascade Mountains and is, consequently, pretty dry and sunny. However, being in the transition zone from the temperate rain forest of the western part of the state, and the deserts of the east, there is a great deal of variety in the climatic zones of the rides within relatively short distances.
Most of the rides, especially at the higher western elevations will be in snow until pretty late in the spring but there are some rides in the desert which can be ridden practically all year if you're so inclined.
Note: If you open the above Google Earth page with Firefox and do not already have the Google Earth plug installed you may get an error message that reads something like "Google Maps API key was registered to a different site". This is a bogus error and you just need to install the plug in. Open the same page with Microsoft Internet Explorer and you will be directed to a site to install the necessary plug in. This is only slightly less time consuming than installing the desktop Google Earth and you do not have the control that you do with that. As this becomes more common more people will have the plug-in installed and it will be more seamless to have Google Earth as part of a page.
