Race # 1  26th Mudslinger 4/6 presented by Peak Sports with stage race Sat/Sun










Since 1987 the Mudslinger has been a fixture in mtb racing and the Corvallis Community and the Northwest. Started by a local group of mountain bikers (Randy Pratt was the official ring leader) and cyclists, this event started out small with only the first person to cross the line to mark times down for the rest of the 20 or so people competing in 1987. I moved to Corvallis in 1990 and in 1991 co-produced the Mudslinger with Randy Pratt until I moved to Bend in 1996 when Jim Fisher took over the Mudslinger. When moving back to the area in 1998 I waited, and after the mudslinger did not happen in 2000, I moved this event to Blodgett the following year to keep the Mudslinger tradition alive. Now with the efforts of many to maintain trails on Starker Forest land with the local IMBA Chapter the Mudslinger is in its 26th year and to celebrate we are including a stage race with a Hillclimb and Super D on Saturday and the 26th Mudslinger on Sunday. Seeing old friends and making new ones is what the Mudslinger is all about and the course will provide many great memories to take it into the next 26 years of Mudslinger Fun!

This year to celebrate the 26th edition the Mudslinger will have 2 days of racing with a Hillclimb and Super D the Day prior starting at noon to add to your Sunday XC time in a Separate Dirt Stage race competition. This event is not part of the series but should be super fun for those that want to claim the title of  the Ultimate Mudslinger. 2014 will be even larger with a new super d course and new XC course as well! Don’t worry panama Canal is waiting! Make sure to come Saturday Night between 4 and 7 pm for the Peak Sports extravaganza with complimentary beer from Sky High Brewing and a presentation at 5:30 from IMBA and the BLM on the Alsea Falls Trail plan. A great way to meet other mountain bikers and meet your local IMBA Chapter Team Dirt.

Race #2 Bear Springs Trap  4/27/14 ST the day prior

Some decades ago Paul Thomasberg Jim Thornton and Petr Kakes designed a course that made racers cry after 50+ miles. Paul’s computer was miscalibrated by 40% and the first year PRO winner was out there for 4 1/2 hrs. The once who didn’t cry got lost . Actually they may have cried too- we just don’t know it.
OK let’s get serious. BST has lot to offer but the name Trap was used for a reason. The Bear Springs area has it’s beauty,  you just need to look at it instead of the wheel in front of you. Since we use portions of the OHV area we do have lot of intersections to deal with. Once you get of the moto trails the challenge will start. The race is known for it’s difficulty as well as for snow on the course whenever mother nature decides to send it in late March and April. As usually Petr and his crew will be there on time to remove the cyclocross sections of the course and welcome you at the finish with the Pilsner Urquell. Dont forget about the Short Track the day prior

New Course for 2014

Cat 2 Spring Thaw 2014 Cat 1 Spring thaw

Race #6 Sisters Stampede 5/25/14 (Registration capped at 600 riders) Last year they turned down 100 riders…please sign up early! Registration is OPEN!

The Sisters Stampede started in 2010 after a revised trail system in Sisters, Oregon called the Peterson Ridge trail. Through cooperation with the US Forest service, the Sisters Trail Alliance created a trail system which caters to all types of trail use including Mountain biking, running, hiking, and equestrian (separate trails).
With approval and cooperation from the US Forest service, the Sisters Stampede was then created to showcase the great trail system in Sisters, and create awareness of how cycling can change the way small towns look at tourism and recreation in Oregon.
A race that begins just steps from Thee Creeks Brewing and Five Pine lodge was just the ticket to get things started.. Throw it on Memorial day Weekend, and its a blast!
After a unique race start led out by a cowboy on horseback, the Sisters Stampede takes riders through a forest covered in Pine, Lava, and sunshine. Beginning with a few miles of double track road is key to stretching out the large fields of riders who have come to be a part of this event. Riders can enjoy two distances depending on skill, and endurance levels (12 miles, or 27 miles). After finishing the race, riders can recover with  food, music, and Three Creeks beer while watching the kids ride obstacles, and participate in their own race.
Register early! Only 500 allowed this year..

Race #10 Pickett’s Charge 6/29/14 (Sunday) YES a Double Series Weekend Final

I hope all of you can look at this as an opportunity, as the Forest Service looks at Saturdays being counted as first weekends so this makes the 7th the first Saturday in June and pushes Picketts to this new date.

Picketts charge started in 1994 as a dual race, part road race and part mountain bike race. It was located out of Meissner Snow Park. It is named for one of Oregon’s Mtn bike pioneers Tom Pickett. Tom introduced me to mountain bike racing in the early 80s. He went to the first US Nationals in Santa Barbara, Ca where a certain Steve Tilford won. 
It was only a dual race for one year. We stayed at Meissner for a few years. It was Mary McConneloug’s first mountain bike race, before her two Olympic visits. We were at Phil’s trail for a few years before we moved to Wanoga and the Steve Larsen trail. 
Our goal is to have the funnest course with the most single track and in 2014 the course will change again…stay tuned!
