Rio Bravo Rumble

Competitors take on the 20-mile bike race during the annual Glinn & Giordano Rio Bravo Rumble.

More than 550 participants and 100 spectators are expected to turn out for the 2018 Rio Bravo Rumble on Saturday, Jan. 13.

In its 14th year, the challenging mountain biking and running event attracts participants from throughout the nation, said Brian Monroe, event coordinator and race director. Monroe noted that most 5K and 10K runners are from within a 3-mile radius of Bakersfield, while most mountain bike and duathletes are from out of town.

“The uniqueness of this event is due to the location. It is held on private land at the mouth of the Kern River Canyon. You cannot access this amazing piece of property any other time,” explained Monroe, adding his thanks to Rio Bravo Ranch and the Nickel family for allowing use of the property. “We have permission for this one day only, so no preriding the course is allowed.”

Competition will be held in the following categories: individual duathlon: 10K run, then a 15-mile mountain bike race, $50; team duathlon: 10K run, then a 15-mile mountain bike race, $80; solo events: 5K run/walk, 10K run, challenging 15-mile mountain bike race, $40; ultra half-marathon, 15-ish-mile run on fire roads and cow trails, very challenging, $50; youth (18 and under) in the above adult races, $20 with paying adult; and short kids races, one for under 8 and one for 9-12, registration will be on the day of the event, free. A $15 late fee will be charged for registration after Jan. 6.

“The (Rumble’s) route has changed over the years to create new challenges, but also in part due to Mother Nature washing out areas with rain,” Monroe said. “Rain is good for filling the river, but bad for race course design.

“I anticipate the course being the same this year, as last year, but one heavy rain in a day can change that,” he said. “The final course is set a week before the event.”

The annual event is presented by Glinn & Giordano Physical Therapy, with support from Clifford & Brown, Leo Mark Hinds, Guinn Construction, Wonderful Pistachios, Fiji Water, POM Wonderful, Paramount Citrus, the Halos and Multi-Business Systems.

Bicycles should not be allowed in any natural area. They are inanimate objects and have no rights. There is also no right to mountain bike. That was settled in federal court in 1996: . It's dishonest of mountain bikers to say that they don't have access to trails closed to bikes. They have EXACTLY the same access as everyone else -- ON FOOT! Why isn't that good enough for mountain bikers? They are all capable of walking....

A favorite myth of mountain bikers is that mountain biking is no more harmful to wildlife, people, and the environment than hiking, and that science supports that view. Of course, it's not true. To settle the matter once and for all, I read all of the research they cited, and wrote a review of the research on mountain biking impacts (see ). I found that of the seven studies they cited, (1) all were written by mountain bikers, and (2) in every case, the authors misinterpreted their own data, in order to come to the conclusion that they favored. They also studiously avoided mentioning another scientific study (Wisdom et al) which did not favor mountain biking, and came to the opposite conclusions.

Those were all experimental studies. Two other studies (by White et al and by Jeff Marion) used a survey design, which is inherently incapable of answering that question (comparing hiking with mountain biking). I only mention them because mountain bikers often cite them, but scientifically, they are worthless.

Mountain biking accelerates erosion, creates V-shaped ruts, kills small animals and plants on and next to the trail, drives wildlife and other trail users out of the area, and, worst of all, teaches kids that the rough treatment of nature is okay (it's NOT!). What's good about THAT?

To see exactly what harm mountain biking does to the land, watch this 5-minute video:

In addition to all of this, it is extremely dangerous: .

The common thread among those who want more recreation in our parks is total ignorance about and disinterest in the wildlife whose homes these parks are. Yes, if humans are the only beings that matter, it is simply a conflict among humans (but even then, allowing bikes on trails harms the MAJORITY of park users -- hikers and equestrians -- who can no longer safely and peacefully enjoy their parks).

The parks aren't gymnasiums or racetracks or even human playgrounds. They are WILDLIFE HABITAT, which is precisely why they are attractive to humans. Activities such as mountain biking, that destroy habitat, violate the charter of the parks.

Even kayaking and rafting, which give humans access to the entirety of a water body, prevent the wildlife that live there from making full use of their habitat, and should not be allowed. Of course those who think that only humans matter won't understand what I am talking about -- an indication of the sad state of our culture and educational system.
